INTRODUCTION This is the adopted standard describing the software functions and interfaces of the Brush PRISMIC Power Management System (PMS). The PMS equipment consists of a PRISMIC, which is a rack mounted, microprocessor based control system with interface modules specifically designed for power system control and load shedding applications. Associated conditioning equipment provides an isolated interface to the power equipment and a Human-Machine Interface (HMI) system provides the operator interface. The equipment is mounted in a free standing Power Management Panel (PMP) with the HMI equipment either supplied in the panel or loose for remote desktop mounting. A Human Machine Interface (HMI) communicates with the PMS and displays all data and operational presets contained within the PMS. Presets may be changed and commands may be issued by the operator via the HMI. The HMI consists of Brush software running under the latest Windows operating system on an appropriate PC. The HMI is used as a graphical interface only it contains no control algorithms algorithms and the PRISMIC will function as normal even when the HMI is switched off. All control algorithms are located within the PRISMIC system itself, not the HMI.

1.1

Dual Configuration

1.2

Not applicable. Definitions

1.2.1

Circuit Breaker Status A generator generator is considered to be on-line and running if its normally open auxiliary contact is closed. All CB closed status signals need to be inhibited when the CB is not in the service position. Discrepancy Monitoring: CB N/O and N/C auxiliary contacts monitoring is included for main power sources.

1.2.2

Master Fault Any primary source of power power (generator (generator or grid incomer i ncomer)) who’s loss could result in fast acting load shed is monitored by a normally closed fault input from a protection relay. The operation of this relay will be an indication of imminent opening of the respective circuit breaker.

1.2.3

Auto/Manual The PMS only controls generators that are selected for auto control. This is indicated to PRISMIC by an auto/manual signal (one for each generator). This signal usually passes through an auto/manual switch on the front of the Generator Control Panel (GCP) or PMP, the governor/AVR units and any other essential control equipment. PRISMIC only takes control when all items are selected for remote or auto operation.

1.2.4

Isochronous The PMS controls generators to achieve an isochronous power system by adjusting the governors and and AVR’s of parallel sets to eliminate the inherent droop. Governors and AVR’s are selected to droop modes, if selected to isochronous then the respective controller sets the reference and PMS control for the power group must be disabled.

1.2.5

Generator MW Capability The MW capability of each machine is preset (adjustable from the HMI). DELETE IF N/A A manual selected generator i s deemed to have a MW capability equal to its MW output; i.e. i .e. manual generators have zero spinning reserve.

1.2.5.1

Automatic Capability Compensation Based Upon TCP/UCP Analogue Signal (Option) PRISMIC utilises an analogue signal that directly indicates capability in MW. The engine manufacture calculates capability within the Turbine Control Panel and this is conveyed to PRISMIC via a 4-20mA signal or via a DCS comms link.

The engine manufacturer will take into account temperature, fuel type etc and as a result PRISMIC will not require these additional signals. 1.2.5.2

Automatic Capability Compensation Based Upon Temperature (Option) PRISMIC utilises an analogue temperature input to modify engine capability. The engine manufacturer supplies a graph relating engine capability to either ambient or turbine inlet temperature. Using the temperature signal PRISMIC is then able to calculate capability. The resultant capability is used within the power sharing, set management and load shedding software, as appropriate, to optimise utilisation of the facility and minimises load shedding without incurring overload.

1.2.5.3

Capability Capabilit y Modificati Modification on Based Upon Fuel Type PRISMIC utilises a digital input to determine current fuel type, (normally gas or diesel). Capability can then be modified in accordance with this fuel type. This can mean simply switching to an alternative preset capability or using an alternative capability/temperature graph. Alternatively, if an automatic digital signal is unavailable, unavailable, the operator operator can select fuel f uel type from the HMI.

1.2.5.4

Manual Capabi Capability lity Modification (Option) In addition to the capability modifications described above, PRISMIC provides a manual de-rate facility. This is in the form of a preset, which has the range of 0 to 100%. This can be used to reduce capability in situations where full capability is unachievable. Capability is calculated as follows: Modified Capability = Capability x De-rate preset. Manual de-rating can be achieved in one of two ways. Either the operator can adjust the preset directly, changing it from say 100% to 95%, or alternatively alternatively the preset preset can be left l eft at the de-rated value at all times and the operator selects de-rate ON/OFF via a command from the HMI or DCS.

1.2.5.5

Peak Capability (Option) In addition to normal capability, each t urbine has a ‘Peak capability’. Peak is higher than normal capability and can be used for short periods. It is used in fast acting load shedding situations, e.g. when a generator trips. When a generator trips, PRISMIC will use the Peak capability when calculating the amount of load to shed to protect the remaining sets. If the remaining sets are left running at a loading greater than normal capability but less than Peak, PRISMIC will start the gradual shed timer. Eventually, when the integrating timer expires, PRISMIC will shed load to below the normal capability level. This gives the operators time to start another set or reduce loading manually.

1.2.5.6

Step Load Limited Capability (Option) The turbine has a limitation on sudden step load application. Many turbines define a ‘step load limit’ which is the maximum amount of load that can be dumped onto the turbine in a single sudden step. This ‘step load limit’ is used to calculate the capability for fast shed situations (i.e. when a generator trips resulting in sudden application of load onto the remaining sets). Step load limited capability is calculated as the current MW loading plus the ‘step load limit’ preset.

1.2.6

Generator MVAr Capability The MVAr capability of each machine is preset (adjustable from the HMI). A manual selected generator generator is deemed to have a MVAr capability equal equal to its MVAr output; i.e. manual generators have zero spinning reserve.

1.2.7

Targets The term ‘Target’ is used throughout this document to describe a calculated or preset value that defines the desired operating level of the associated equipment. All auto generators have a target value for MW, MVAr, Voltage and Frequency. These targets are continuously calculated at all times for all modes of operation including sharing.

Power Groups PRISMIC considers adjacent bus sections to be interconnected if connecting bus couplers or interconnectors are closed so that an electrical connection exists. A group of generators, grid incomers and loads connected to a bus or interconnected buses is known as a Power Group; a power group must contain at least one power source.

1.2.9

Power Group MW Capability For each group of interconnected generators, the sum of the MW capabilities is referred to as the ‘Power Group MW capability’.

1.2.10

Power Group MW Load For each group of interconnected generators, the sum of generator MW loading is referred to as the ‘Power Group MW load’.

1.2.11

Power Group MW Spinning Reserve For each group of interconnected generators, power group MW spinning reserve is the difference between the MW capability of a power group and the total MW load in that power group as defined above. When the power group contains a grid incomer, the spinning reserve is calculated both including and excluding the grid capability and load.

1.2.12

Power Group MVAr Capability For each group of interconnected generators, the sum of the MVAr capabilities is referred to as the ‘Power Group MVAr capability’.

1.2.13

Power Group MVAr Load For each group of i nterconnected nterconnected generators, generators, the sum of generator MVAr loadings is referred to as the ‘Power Group MVAr load’.

1.2.14

Power Group MVAr Spinning Reserve For each group of interconnected generators, power group MVAr spinning reserve is the difference between the MVAr capability of a power group and the total MVAr load in that power group as defined above. When the power group contains a grid incomer, the spinning reserve is calculated both including and excluding the grid capability and load.

1.2.15

Grid Incomer The site is connected to a grid that is assumed to be an ‘infinite’ system. By this we mean that the voltage and frequency of this system are ‘stiff’ i.e. unaffected by fluctuations in site l oad and import/export of MW or MVAr. When a site bus is connected to a grid incomer, PRISMIC abandons voltage and frequency control of any generators connected to that bus, (unless the grid incomer contains a tap changer).

1.2.16

Grid MW And MVAr Capability The MW and MVAr capabilities of each grid incomer are preset (adjustable from the HMI).

1.2.17

Presets The word ‘Presets’ is frequently used throughout this document. Presets are operator adjustable settings that are used within t he real time embedded part of PRISMIC but displayed and edited via the HMI. Presets are stored in 3 locations, RAM, Flash and within the code (known as defaults). For control purposes, PRISMIC always regards the RAM presets as being current and uses these values within the control algorithms. When the operator changes a preset on the HMI, it is sent from the HMI to the embedded part of PRISMIC. Here it i s put into RAM presets. When the operator is happy with these new preset settings, he or she should store these in Flash. This is a non-volatile memory and values will be retained after a power down. On power up, PRISMIC will transfer Flash presets into RAM.

During the power up, PRISMIC will check that the Flash presets are valid and not corrupted. If an error is detected, Flash presets are ignored and instead PRISMIC will load a full set default presets into RAM. Default Presets are hard coded by the software engineer during development and commissioning. At the end of commissioning, default presets settings are programmed to be equal to the l atest site settings.

FUNCTIONS OF THE PRISMIC

2.1

Introduction

2.1.1

Generator / Grid / Interconnec Interconnector tor Power Measurement

Page: 9 of 51

The MW loading of each power source is monitored by a single phase sensing CT and the appropriate bus-section VT signal. The signals are fed into PRISMIC via isolating CTs and VTs and the power output derived by instantaneous multiplication. PRISMIC utilises the same sensing CTs and VTs for MVAr load measurement (where required), introducing a 90º phase shift in sensing volts. The system voltages and frequencies are directly monitored from bus VTs. Alternatively: The MW loading of each generator and grid is monitored by transducers (supplied by others) mounted within the switchgear. The transducers provide 4-20mA signals that represent MW and MVAr. 2.1.2

Security Of Output Signals The following measures ensure that a single fault within the PRISMIC cannot lead to spurious output signals: a) The PRISMIC is designed designed with with outputs that must be be energised to cause change change and close contacts to shed loads. b) PRISMIC software monitors a number number of conditions conditions every 10 ms. Only if all conditions conditions are healthy, does PRISMIC issue a pulse to the watchdog circuit. If this circuit does not receive a pulse for approximately 20 ms, the watchdog circuit ‘drops out’ de-energising all the PRISMIC digital outputs. After correcting the fault, the PRISMIC microprocessor system must be reset using a pushbutton mounted in the PRISMIC rack. The PRISMIC indicates the healthy/fault status of each of the monitored conditions using a series of LEDs. c)

During the initialisation period period after power power up, the input signals used used to monitor the power system are scanned and memory is updated before any output signal is enabled. This prevents spurious outputs being given caused by incorrect data.

Output signals such as load shed trip and generator generator start are f itted with guard relays to prevent accidental outputs should an output circuit fail to an ON state. The guard relays are arranged to be on separate modules to the relays they are guarding, thus ensuring one hardware fault cannot give a spurious output. For an output to be given the guard relay must be de-energised before the output signal is issued. 2.1.3

Governor And AVR Adjustment

2.1.3.1

Operation When Connected To A Grid/Utility PRISMIC treats a grid/utility as an infinite bus. Therefore it ceases voltage and frequency control for any power group which is connected to a grid/utility. Load shedding and inhibit start is handled in the normal manner when connected to a grid/utility; that is, the grid capability and load are included in the calculation. Starting and stopping generators will generally only be automatic when in “Grid Target” mode in which case the steady state grid capability becomes the set target i.e. the grid has no spinning reserve. Note load variations are taken by the generators thus impacting the local spinning reserve. If the grid rated capacity is low compared to the site load then generator automatic start and stop may be applicable to generator target mode. Power flow to and from the grid/utility can be controlled according to the modes of operation as described in Clauses 2.1.3.5 and 2.1.3.6.

Governor And AVR Operating Modes In order to control power flow, both active and reactive, PRISMIC expects generator governors and AVRs to operate in droop mode. Droop mode is defined as a characteristic where, internal to the governor or AVR, the target control frequency or voltage value is reduced in proportion to increasing generator load. Thus, generators may operate in parallel in a stable manner. PRISMIC or an operator may then issue raise/lower signals to the governors and AVRs to alter the power flows, VAr flows or power factors of the generators and the frequency and voltage of the busbar. Other governor or AVR modes may be accommodated by special arrangements.

2.1.3.3

Power Group Frequency Control PRISMIC maintains the steady state frequency for a power group at a frequency demand setpoint by adjusting the governor setpoints using raise/lower pulses issued via volt free contacts in the PMP. When the frequency is outside i ts deadband deadband (demand level ± deadband deadband level), PRISMIC issues i ssues a raise or lower pulse accordingly. The length of the pulse is proportional to the size of the frequency error. The length of the pulse for a given error can be adjusted using the frequency attenuation preset. The preset has a range of 1 to 50; a higher number setting gives a shorter pulse. The period between the leading edge of successive pulses is known as the governor slug and can be adjusted using the HMI. Frequency control is closely linked to MW control (Clause 2.1.3.5) in that frequency and MW raise/lower signals are combined to produce a single raise/lower output for each generator.

2.1.3.4

Power Group Voltage Control PRISMIC maintains the steady state voltage for a power group at a voltage demand setpoint by adjusting AVR setpoints using raise/lower raise/lower pulses issued via v olt free contacts in the PMP. When the voltage is outside its deadband (demand level ± deadband level), PRISMIC issues a raise or lower pulse accordingly. accordingly. The length of t he pulse is proportional proportional to the t he size of the voltage error. The length of the pulse for a given error can be adjusted using the voltage attenuation preset. The preset has a range of 1 to 50; a higher number setting gives a shorter pulse. The period between the leading edge of successive pulses is known as the AVR slug and can be adjusted using the HMI. Voltage control is closely linked to MVAr control (Clause 2.1.3.6) in that voltage and MVAr raise/lower signals are combined to produce a single raise/lower output for each generator.

2.1.3.5

Generator Power Control PRISMIC calculates a target MW value for each auto generator and attempts to maintain this value by adjusting the governor setpoints using raise/lower pulses issued via volt free contacts in the PMP. The target MW value is calculated depending upon the mode of operation, as described below. When the monitored MW value is outside its deadband (target MW ± deadband level), PRISMIC issues a raise or lower pulse accordingly. The length of the pulse is proportional to the size of the MW error. The length of the pulse for a given error can be adjusted using the MW attenuation preset. The preset has a range of 1 to 50, a higher number setting gives a shorter pulse. The period between the leading edge of successive pulses is known as the governor slug and can be adjusted using the HMI. MW control is closely linked to frequency control (Clause 2.1.3.3) in that frequency and MW raise/lower signals are combined to produce a single raise/lower output for each generator.

2.1.3.5.1

MW Modes Of Operation Several types of power control are possible. These are described in detail below.




Issue: A

Page: 11 of 51

a) Setpoint Target Mode (Also Known As Base Load Mode) In this mode the generator is held at a preset target. This can be in MW or a percentage of capability. Non-target Non-target machines will take up the fluctuations in site loading. If t he non-target non-target machines reach maximum or minimum loading levels, the target machines will relax their targets to prevent overload or reverse power situations. b) Sharing Mode This is the most common mode of operation. Any machine that is not in Target mode is deemed to be in Sharing mode and will simply share load, in percentage terms, with other sharing machines. c) Cable Setpoint Target Mode Not applicable. d) Platform/Site Setpoint Target Mode Not applicable. e) Grid Incomer Setpoint Target Mode In situations where PRISMIC has control of generators on a site that is connected to a grid, it is possible to control the grid power import or export to a preset target. The target would normally be in MW. In the case of multiple grid connections, each grid will have a MW target. These targets are summed together if multiple grids are connected in parallel. Whilst in this mode, individual sets can also be selected for base load mode as described above. Provided sufficient machines are left in non-target (sharing) mode PRISMIC will maintain both the individual base load targets and the incomer setpoint target. Selective targets (i.e. incomer or generator) will be relaxed to prevent overload or reverse power of the machines. Note: When Incomer Setpoint Target Mode is selected, this also applies to the VAr control. f)

Group Setpoint Target Mode In situations where PRISMIC has control of generators on a site that is connected to a grid, it is possible to control the t otal site generation to a preset target. The target would normally normally be in MW. In the case of multiple grid connections, each grid will have an associated group MW target. These targets are summed together if multiple grids are connected in parallel. Whilst in this mode, individual sets can also be selected for setpoint target mode as described above. Provided sufficient machines are left in non-target (sharing) mode PRISMIC will maintain both the individual generator setpoint targets and the group setpoint target. Selective targets (i.e. group or generator) will be relaxed to prevent overload or reverse power of the fluctuating machines. Note: When Group Setpoint Target Mode is selected, it also applies to the VAr control.

2.1.3.6

Generator Reactive Power Control PRISMIC calculates a target MVAr value for each auto generator and attempts to maintain this value by adjusting AVR setpoints using raise/lower pulses issued via volt free contacts in the PMP. The target MVAr value is calculated depending upon the mode of operation, as described below. When the monitored MVAr level is outside its deadband (target MVAr ± deadband level), PRISMIC issues a raise or lower pulse accordingly. The length of the pulse is proportional to the size of the MVAr error. The length of the pulse for a given error can be adjusted using the MVAr attenuation preset. The preset has a range of 1 to 50; a higher number setting gives a shorter pulse. The period between the leading edge of successive pulses is known as the AVR slug and can be adjusted using the HMI.

MVAr control is closely linked to voltage control (Clause 2.1.3.4) in that voltage and MVAr raise/lower signals are combined to produce a single raise/lower output for each generator. 2.1.3.6.1

MVAr Modes Of Operation Several types of reactive power control are possible. These are described in detail below. This description assumes that tap changers are not involved. Tap changer control is described separately. There are two main modes of operation. The first is sharing mode and the second is setpoint target mode. Setpoint target mode is also subdivided into VAr setpoint target mode and PF setpoint target mode. a) MVAr Setpoint Target Mode In this mode the generator is held at a preset target. This can be in MVAr (VAr setpoint target mode) or a percentage of MW loading, (PF setpoint target mode). PF setpoint target mode is only selectable if the machine is already selected for MW setpoint target mode. When in PF setpoint target mode the derived VAr target is calculated as follows: VAr target = MW setpoint target x Tan (Cos-1 PF target) Non-target machines will take up the fluctuations in site loading. If the non-target machines reach maximum or minimum loading levels, the target machines will relax their targets to prevent overload or reverse power situations. b) MVAr Sharing Mode This is the most common mode of operation. Any machine that is not in Target mode is deemed to be in Sharing mode and will simply share load, in percentage terms, with other sharing machines. c) Grid Incomer MVAr Or P.F. Setpoint Target Mode Note: When Incomer Setpoint Target Mode is selected, this applies to both watts and vars control. In situations where PRISMIC has control of generators on a site that is connected to a grid, it is possible to control the grid reactive power import or export to a preset target. The target can be in MVAr, P.F., or both, (operator selectable). When in Incomer PF setpoint target mode, the derived VAr target is calculated as follows: VAr target = Incomer MW setpoint target x Tan ( Cos-1 Incomer PF target ) In the case of multiple grid connections, each grid will have a MVAr target, (either preset or calculated from desired PF). These targets are summed together if multiple grids are connected in parallel. Whilst in this mode, individual sets can also be selected for MVAr setpoint target mode as described above. Provided sufficient machines are left in non-target (sharing) mode PRISMIC will maintain both the individual generator setpoint targets and the incomer setpoint target. Selective targets (i.e. incomer or generator) will be relaxed to prevent overload or reverse power of the fluctuating machines. d) MVAr Or P.F. Group Setpoint Target Mode Note: When Group Setpoint Target Mode is selected, this applies to both watts and vars control. In situations where PRISMIC has control of generators on a site that is connected to a grid, it is possible to control the total site generation to a preset target. The target can be in MVAr or P.F. or both, (operator selectable).

When in Group PF setpoint target mode, the derived VAr target is calculated as follows: VAr target = Group MW MW setpoint target x Tan (Cos-1 Group PF target ) In the case of multiple grid connections, each grid will have an associated group MVAr target, (either preset or calculated from desired PF). These targets are summed together if multiple grids are connected in parallel. Whilst in this mode, individual sets can also be selected for MVAr setpoint target mode as described above. Provided sufficient machines are left in non-target (sharing) mode PRISMIC will maintain both the individual generator setpoint targets and the group setpoint target. Selective targets (i.e. group or generator) will be relaxed to prevent overload or reverse power of the fluctuating machines. 2.1.4

Load Shedding, And Inhibiti Inhibition. on. PRISMIC is capable of tripping load feeders to avert cascade failure of the generation system. Load shedding occurs due to the following reasons: a) Sudden loss of a generator/grid leading to a system overload. overload. b) Sudden loss of a bus-tie or interconnector. interconnec tor. c)

Gradual increase in load leading to a system overload.

d) System under frequency. frequency . The sequence of load shedding is defined by a shedding priority table configured via the HMI. 2.1.4.1

Load Shedding Prioriti Priorities es The HMI provides a table that contains all sheddable loads. The first load to be shed is at the top and the last to be shed at the bottom. The order may be changed using an edit facility. If the power system is split into separate power groups and an overload occurs within only one power group, PRISMIC sheds loads on the overloaded power group only. The loads are shed in the table order but only appropriate loads are shed. The load shedding priority table is stored in non-volatile memory within PRISMIC and is restored after a power down.

2.1.4.2

Load Shedding Signals The MW values of all sheddable loads may be monitored using transducer inputs or may be user-defined presets from the HMI. During a load-shed sequence, PRISMIC does not attempt to trip a feeder more than once if it fails to open at the first attempt. Other load feeders are tripped instead. This guards against a fault in the tripping circuitry. Once a trip signal has been issued, the feeder is not available for further trips until the shed status is accepted via the HMI. The load shed outputs are coupled with a load shed guard signal, which is de-energised to allow load shedding to occur. The load shed guard output is i nterlocked with the shed outputs in the PMP to ensure that loads are not shed spuriously due to a single hardware failure.

2.1.4.3

Generators In Manual Control Generators selected for manual control when in parallel with generators in automatic (PMS) control will have a capability equal to their load. However, when all generators in parallel are in manual control the load shedding calculation is changed to enable utilisation of the capacity available under drooping characteristic, as follows: •

•

•

Gradual Overload: The generator capability equals compensated capability as for automatic control/shedding. Fast Acting Load Shedding: The generator capability equals compensated capability as for automatic control/shedding. Under Frequency: This mode is disabled because of the drooping frequency when in manual control.

Fast Acting Load Shedding The following actions cause the fast acting shed software to be invoked: a) Any of the generator breakers opening b) Any of of the generator fault inputs becoming true. c)

Any grid breaker opening.

No other breaker operations can cause fast acting load shedding to be invoked. It should be noted that it is assumed that the generator fault inputs come f rom the protection relays and may arrive at PRISMIC a few milliseconds before the breaker status signal changes state. Once a breaker opens or a fault input becomes true, PRISMIC recalculates the power group capability. The new capability i s compared with the pre-disturbance power power group load. If there is a capability shortfall, PRISMIC trips sufficient loads to remove the overload. The loads are shed in priority table order. After a preset period (MW Overload Recovery Time), PRISMIC determines determines if an overload still exists. The time delay allows the system to stabilise. Further loads are then shed if there is a remaining overload. When a bus-tie or interconnecting cable opens or trips on f ault, the system may be split into two separate groups. At the instant of separation PRISMIC may shed load in either group to protect the now isolated generation. Prior to the system splitting, PRISMIC will monitor the power flow through the bus-tie/interconnector to allow the calculation of the local group load on either side of the relevant breaker. 2.1.4.5

Gradual Overload Load Shedding If a power group’s load increases above its capability, an integrating counter is started. The count rate is proportional to the magnitude of the overload and is calculated as a percentage of the capability of the power group. A preset gradual overload limit is set-up via the HMI. If the overload is maintained for a time such that the integrating counter reaches the preset gradual overload limit, load shedding is initiated. If the overload is removed at any point, the integrating counter is reset to zero. PRISMIC trips sufficient loads to remove the overload. Loads are shed in accordance with the priority table and rules specified in Load Shedding Priority section. After a preset preset time period (MW Overload Recovery Time), PRISMIC determines determines if an overload still exists. The time delay allows the system to stabilise. Further loads are shed if there is a remaining overload.

2.1.4.6

Under Frequency Load Shedding Load shedding is initiated when the power group frequency falls below the preset ‘Under Frequency Load Shed Level’ for the duration of the preset ‘Under Frequency Load Shed Time’. A preset block of l oads is shed when the timer expires. This block of loads is specified from t he HMI as either a number of loads to shed or a minimum MW value by which the power group load must be reduced, or both. After the preset preset ‘Under Frequency Recovery Time’ the t he f requency requency is compared with the preset preset ‘Under Frequency Recovery Level’. If the frequency has not recovered sufficiently, another block of loads is shed.

2.1.4.7

Cable Overload Load Shedding Not applicable

2.1.4.8

Load Feeder Inhibit Inhibits s Inhibit start signals are issued to prevent the starting of feeders whose preset starting power level is greater than the power group spinning reserve. Each load feeder is assigned a preset MW start level, which is adjustable via the HMI. The inhibit is in the form of a volt free contact that is opened in the inhibit condition thus allowing a start in the event of the PMS being off.

The HMI provides an override facility, which enables the operator to cancel all inhibits, thus allowing all loads to be started. Note: In contactor control circuits the latch contact will need to be across the inhibit. 2.1.4.9

Generator Set Management PRISMIC may be configured to m anage the starting and stopping of generators. generators. This feature is known as “generator set management”. Clause 0 defines all set management functionality for each set.

2.1.5.1

Duty Selection The HMI provides a duty table containing the names of the relevant generators which defines the order in which generators are automatically started. The order may be changed using an edit facility. The first generator to start is displayed at the top and the last to start at the bottom.

2.1.5.2

Starting Generators Prime movers can normally be started locally at their respective control unit. This action is completely separate to any start sequences performed by PRISMIC. Generators can be started automatically by PRISMIC or start sequences can be operator initiated via the HMI or DCS. PRISMIC can start generators in two ways: single stage or two stage. The two stages are starting and synchronising and the single stage approach combines these into a starting/synchronising process. Single stage starting does not require a running signal to be input into PRISMIC and has a single fail to start/synchronise alarm. Two stage starting has separate fail to start and fail to synchronise alarms. This project utilises single or two stage starting.

Single Stage Starting (Option) If all of the conditions above are satisfied, PRISMIC will issue a start/synchronise signal and initiate a software fail to start/synchronise start/synchronise timer. If the t he breaker closes before before the timer expires, expires, the software soft ware timer is stopped and the generator is deemed to be online and ready to accept load. If the timer expires however, PRISMIC issues a fail to start/synchronise start/synchronise alarm. The alarms are reset via the HMI. If a generator fails to start or synchronise, PRISMIC immediately attempts to start the next available duty generator. This only applies if the generator was started automatically; manually initiated start sequences are terminated as soon as the alarm is issued. The conditions upon which PRISMIC starts generators are described below.

2.1.5.4

Two Stage Starting (Option) If all of the conditions above are satisfied, PRISMIC will issue a start signal and initiate a software fail to start timer. If the running input is received before the timer expires, the turbine is deemed to be ready to synchronise. The timer is stopped and PRISMIC issues a synchronise signal. This initiates a synchronise sequence. If, however, the timer expires before the running signal is received, PRISMIC issues a fail to start alarm and no attempt at synchronisation is made. When the synchronise sequence sequence is initiated, i nitiated, a software fail to synchronise synchronise timer is i s started. If t he breaker closes before the timer expires, the timer is stopped and the generator is deemed to be online and ready to accept load. If the timer expires however, PRISMIC issues a fail to synchronise synchronise alarm. The alarms are reset via the HMI. If a generator fails to start or synchronise, PRISMIC immediately attempts to start the next available duty generator.

Minimum Generators To Run This is a preset, user-adjustable from the HMI. If less generators are running in the power group than the minimum required, PRISMIC attempts to start the generator with the highest position i n the duty table, which is not already running, in order to meet this target. This requirement overrides the stopping of generators due to high spinning reserve (Clause 2.1.5.5.1).

Manually Manuall y Initiated Starting PRISMIC provides the operator with a method of manually initiating a start from the HMI. This is in the form of a menu from which the operator selects the name of the generator to start.

2.1.5.5

Stopping Generators Prime movers can normally be stopped locally at their respective control unit. This action is completely separate to any stop sequences performed by PRISMIC. Stop sequences can be operator initiated via the HMI or DCS. When stopping a generator, PRISMIC issues governor and AVR lower signals to offload the Watts and VArs. When the generator approaches zero loading, PRISMIC issues a breaker trip signal. Whilst offloading the generator, PRISMIC constantly monitors the state of the spinning reserve. If it appears that the loading has increased such that the remaining generators in the power group would be overloaded, PRISMIC aborts the offload process and the generator will revert to its previous control mode. m ode. Option 1: PRISMIC deems the opening of the breaker to be end of the offload sequence. Cooling and stopping of the turbine is handled by the Turbine Control Panel. Option 2: After the breaker has opened, opened, the t he machine is allowed to run on for a preset period to allow the prime mover to cool down. When the run-on timer expires, expires, a stop signal is issued. The stop sequence is terminated when the running signal is removed. The conditions upon which PRISMIC stops generators are described below.

2.1.5.5.1 2.1.5.5. 1

Stopping Due To A High Spinning Reserve If the t he power power group spinning reserve rises above a preset level for a period greater than a preset time, PRISMIC will offload the generator in the power group with the lowest duty selection; see duty selection above (Clause 2.1.5.1). Both the stop level and the timer are adjustable via the HMI.

2.1.5.5.2 2.1.5.5. 2

Manually Initiated Stopping PRISMIC provides the operator with a method of manually initiating an offload from the HMI. This is in the form of a menu from which the operator selects the name of the generator to stop. Upon receipt of the stop command, PRISMIC checks that there is sufficient spinning reserve to allow the generator to be offloaded without the remaining generators becoming overloaded.

2.1.6

Tap Changer Control PRISMIC may be configured to manage one or more tap changers. PRISMIC issues raise and lower signals to adjust the tap position. Tap raise will increase the transformer turns ratio. Tap lower will decrease the transformer turns ratio. Various modes of operation are possible

2.1.6.1

Voltage Control When a platform/site has no local generation, PRISMIC adjusts the tap to maintain the bus v olts within an associated voltage deadband.




Issue: A

Page: 18 of 51

VAr Control When two platforms/sites are connected via a cable and tap changer(s), PRISMIC can distribute VArs between the two sites sites by adjusting the tap(s). VAr distribution adjustment using a tap changer is relatively coarse (when compared to AVR control) and as a result a separate VAr deadband is provided for the tap changer. Assuming that the tap changer converts from bus voltage to a higher v oltage, a tap raise signal will increase the HV side of the transformer and lower the bus voltage. PRISMIC will maintain the bus voltage at nominal by issuing raise pulses to the AVRs. This will result in an increase in VAr generation on this bus. As a result, a raise tap signal will increase VArs generated on the local bus and vice v ersa.

2.1.6.3

Nominal Tap Position Control When the tap changer is disconnected, PRISMIC will tap to a nominal preset position. The preset can be adjusted to allow voltages to be matched either side of a breaker to allow faster synchronisation.

Bus Tie / Group Synchronisa Synchronisation. tion. The following facility is be used in conjunction with an independent proprietary automatic synchroniser synchroniser to enable e nable synchronising of multiple generators across Bus Ties, or Interconnectors when reconfiguring the power system. When a synchronise command is issued by the operator, PRISMIC will issue a synchronise initiate signal to the appropriate synchroniser. This is used by the synchroniser relay logic to route the appropriate VT signals onto the synchroniser. The synchroniser then issues raise/lower raise/lower frequency and voltage signals into PRISMIC which in turn responds by adjusting the appropriate targets. When the running and incoming supplies are synchronised, the breaker is closed by the synchroniser. A software fail to synchronise timer is started when when group synchronise synchronise is initiated. If the breaker fails to close before the timer expires, the synchronise sequence is aborted and a fail to synchronise alarm is issued.

Commissioning Commissioni ng Mode PRISMIC enters commissioning mode in response to an operator request via the HMI after first correctly entering the Maintenance password.

WARNING: On entering this mode, PRISMIC clears all digital outputs and stops performing any control functions. This mode allows the operator to set or clear any digital output without any hardware guards, software protection or safety checks. If this mode is selected when operating with a live system then all digital outputs must first be inhibited or disconnected. PRISMIC continues to read inputs in the normal manner for display on the HMI. 2.1.10

Power System Alarms These alarms indicate possible problems with the electrical system that PRISMIC is controlling. These alarms are active for the duration of the problem. a) Gradual Overload Load Shed This alarm indicates that load has been shed due to a gradual overload situation. The alarm is reset from the HMI, providing the overload has cleared and the MW overload re-trip timer has expired. b) Fast Acting Load Shed This alarm indicates that load has been shed due to the sudden loss of capability, i.e. the loss of a generator or grid/utility breaker. The alarm is reset from the HMI, providing the overload has cleared and the MW overload re-trip timer has expired.

c) Under Frequency Load Shed This alarm indicates that load has been shed due to an under frequency situation. The alarm is reset from the HMI, providing the under frequency situation has cleared and the under frequency re-trip timer has expired. d) Low Spinning Reserve If the MW spinning reserve of any power group falls below the low spinning reserve alarm level for the duration of the timer, PRISMIC issues this alarm. This alarm will clear automatically when the power group spinning reserve exceeds the alarm level. e) High Spinning Reserve If the MW spinning reserve on any power group exceeds the high spinning reserve alarm level for the duration of the timer, PRISMIC issues this alarm. This alarm will clear automatically when the power group spinning reserve is less than the alarm level. f)

Generator Failed To Start If PRISMIC issues a start signal, it expects to receive a running signal within a preset time. If the signal is not received PRISMIC PRISMIC issues this alarm. The alarm is reset using the HMI.

g) Generator Failed To Synchronise If PRISMIC issues a synchronise signal, it expects the breaker to close within a preset time. If the breaker does not close PRISMIC issues this alarm. The alarm is reset using the HMI. h) Power Sharing Mismatch This alarm is displayed if the generators are not sharing power within the sharing deadband for more than a preset time. This alarm is automatically reset when power is being shared within the deadband. i)

VAr Sharin Sharing g Mismatch This alarm is displayed if the generators are not sharing VArs within the sharing deadband for more than a preset time. This alarm is automatically reset when the VArs are being shared within the deadband.

j)

Grid / Generator Generator Targets Targets Unachievable Unachievable This alarm is displayed if the target MW, MVAr or PF cannot be achieved for either Grid Target Mode or Group Target Mode for more than a preset time. This alarm is automatically reset when the actual MW, MVAr or PF levels within the deadband.

2.1.11

PRISMIC Watchdog Alarms These alarms indicate a possible problem with the PRISMIC system itself. Watchdog alarms are critical and result in the watchdog dropping out inhibiting all output relay operation. These can be cleared only when the problem has been corrected and PRISMIC has been reset either by switching off and on or by pressing the reset push-button on the front of the PS-UW on the PRISMIC rack. The PS-UW card has diagnostic LED indication associated with some of the following alarms these are normally illuminated when healthy and extinguished on fault. The LED number is indicated were applicable. Utilities LED 1 5 2 6 3 7 4 8

a) 24V Supply Failure - LED 1 This alarm is displayed if the 24V DC auxiliary power supply has dropped below (14.75V). PRISMIC watchdog is operated. b) STE Bus Bus Timeout Fault - LED 2 If a PRISMIC card fails to respond to an access request from the PRISMIC processor then this alarm is issued. PRISMIC watchdog is operated. c) Busbar Voltage Measurement (VT) Fault - LED 3 PRISMIC determines which buses should be live from the status of the generator breakers. If a VT signal is not present for a bus that PRISMIC regards as being live, the watchdog drops out and the alarm is issued. d) Diagnostics Diagnosti cs Error - LED 5 This indicates an error in the PRISMIC control software such as a divide by zero or an unexpected interrupt. This would normally not occur in proven software. This fault is also associated with an error code as displayed by the red LED on the main control processor. The code is given as a series of long and short flashes. PRISMIC watchdog is operated. e) Frequency Transducer Card Fault - LED 6 The PS-FT card has its own self-contained software. If the software stops cycling, the watchdog drops out and the alarm is displayed. f)

Main Loop Code Not Called - LED 7 Every 10ms an interrupt routine is called that increments a count. In addition it also checks the status of a flag t hat is only set to true in the main loop. If the flag is true it indicates that the main loop code is still functioning. The flag is then immediately cleared along with count. If the flag is false, the count is compared with a constant. If the count is greater than the constant it indicates that the main loop code has not been called recently. This alarm is displayed and the watchdog is operated.

g) Busbar Frequency Measurement Fault - LED 8 PRISMIC determines which buses should be live from the status of the generator breakers. If a frequency reading is zero for a bus that PRISMIC regards as being live, the watchdog drops out and the alarm is issued. 2.1.12

PRISMIC Microsys Microsystem tem Alarms These alarms indicate a possible local memory problem when changing adjustable control parameters or on power up. a) Unsuccessful Flash Write When the operator saves parameters to non-volatile FLASH memory, PRISMIC checks that the values have been saved correctly. If an error has occurred, this alarm is displayed. b) Unsuccessful Flash Read On Power Power Up, Defaults Loaded When PRISMIC is switched on, it checks that all values stored in non-volatile FLASH memory are uncorrupted. If the values are OK, PRISMIC copies the FLASH values into working memory stores. If, however, the FLASH data memory has been corrupted, PRISMIC copies default values into working memory stores. When this occurs, PRISMIC displays this alarm to indicate that FLASH memory is corrupted and defaults are being used.

c) Unmatched Presets (FLASH vs. RAM) PRISMIC checks that the presets stored in ordinary RAM match t hose stored in non-volatile FLASH memory. If there is a mismatch, this alarm is given to warn the operator that the revised presets (set up via the HMI) have not been stored in FLASH memory and hence will be lost on power down. W hen presets presets are changed, changed, the th e operator should use the ‘Write nonvolatile Memory’ facility to make sure that new preset values are stored in FLASH memory and will thus be restored after the next power down. d) Unmatched Load Shed Priority (FLASH vs. vs. RAM) RAM) PRISMIC checks that the priority table stored in ordinary RAM matches that stored in nonvolatile FLASH memory. If there is a mismatch, this alarm is given to warn the operator that the revised priority table (set up via the HMI) has not been stored in FLASH memory and hence will be lost on power down. When the priority table is changed, the operator should use the ‘Write non-volatile Memory’ facility to make sure the new priority table is stored in FLASH memory and will thus be restored after the next power down. 2.1.13

External Communica Communication tion Interfaces The PRISMIC control system provides a number of interface ports for connection to other systems as follows.

2.1.13.1

PRISMIC To PRISMIC Connect Connection ion Not applicable

2.1.13.2

Deterministic Ethernet Network Not applicable.

2.1.13.3

Human Machine Interface (HMI) Connection A communications communications port is configure c onfigured d as a Modbus slave allowing a PC running the Brush HMI software to be connected for commissioning and general operator interface work. This interface generally operates at 38.4kb/sec.

2.1.13.4

Event Logging Interface A communications communications port is configured for transmission transmission of digital event logging information and time stamps. The data is encrypted condensed format that is interpreted by the Event Logger application. Changes of state of digital inputs to and outputs from the PRISMIC system are continuously logged to a daily file for local or remote analysis as required. The Event Logger application runs independently of the HMI application and uses a separate comms port. This interface generally operates at 9.6kb/sec

2.1.13.5

DCS/SCADA Link A communications communications port is configured as a Modbus slave allowing a DCS/SCADA to communicate with PRISMIC. Data may flow in either direction. This interface also allows certain preset values to be adjusted and/or certain control modes to be initiated from the DCS. This interface generally operates between 9.6 and 115kb/sec selected to suit the master DCS/SCADA system.

2.1.14

Modbus Communi Communications cations Protocol The microsystem communicates using Modbus RTU. Isolation and media conversion is in the form of proprietary devices fitted internal to the PMS panel. The project interface may be in the form of isolated RS485 or fibre optic dependent on project specification. The data highway operates using the AEG Modicon Modbus RTU protocol with the SCADA/DCS acting as master and the PRISMIC acting as slave.

PRISMIC PMS HMI APPLICA APPLICATION TION The following is based on version 1.076 of the HMI application. The HMI is a Windows application designed to act as a user interface for operators and commissioning engineers working with PRISMIC microsystems. The HMI application uses a dedicated communications application known as a Modbus OPC server to access data within the PRISMIC microsystem. For increased security of operation, the PRISMIC PMS control software and the HMI run on separate microprocessor systems, with a Modbus link providing communications between the two.

HMI Displays When the HMI application starts, the Power System Single Line Diagram for the project is displayed. If HMI is able to communicate with the PMS then the breaker symbols and busbar voltage and frequency values should be shown with appropriate states and values. The Single Line Diagram appears within a child window of the application. Other child windows may be created to view other aspects of the PMS data or view the data i n different ways. These child windows are known as Displays within the HMI application. Displays for Generator Data, Load Shedding Priorities, Vector Diagram and others are available and may be created using the Display | ParticularDisplay menu selection. Each of the Displays is equipped with scroll bars so that, when the Display is resized to be smaller, it is possible to scroll to view any part of the display. It is possible to create a number of copies of a particular display using the Display | ParticularDisplay menu selection a number of times. The HMI application is a Windows Multiple Document Interface (MDI) application. MDI allows the user to tile and cascade child windows or displays using the Window | Tile or Window | Cascade menu selections. This combination of features allows extreme areas of very large displays to be viewed concurrently. It is possible to close child windows or displays in the normal way. However HMI will not allow less than one Single Line Diagram Display. If the user attempts to close the last remaining Single Line Diagram Display then HMI will ignore the close request.

Alarm Display Configura Configuration tion The system is configured to display 5 alarm states, the following gives details of these alarm configurations. Note: A latched active alarm is an alarm that was active, but is no longer active - and has not been cleared/accepted by the user. When an alarm is active it will be displayed on its group alarm page and on the alarms list page. An audible alarm alarm is given if the alarm is active. active. The alarm banner (at the foot of the page) appears when there is an unacknowledged alarm on an alarm page. The name of the page appears in the banner and the HMInt may display more than one alarm page banner by alternating them. The colour should reflect the highest status alarm on a particular page, for this purpose red is higher than purple.

MEANING Alarm active and unacknowledged Alarm active and acknowledged acknowledged Alarm previously active and unacknowledged Alarm previously previously active and acknowledged Alarm not active

1) An unacknowledged active alarm flashes red in the alarm list and in the specific alarm group. If an alarm group has an unacknowledged active alarm, the name of that alarm group flashes red in the banner. 2) An acknowledged acknowledged active active alarm is displayed displayed with a steady red background background in the alarm alarm list and in the specific alarm group. Once all of the alarms in an alarm group are acknowledged, the name of that alarm group ceases to appear in the banner. 3) An unacknowledged latched active activ e alarm flashes purple in the alarm list and in the specific alarm group. If an alarm group has an unacknowledged latched active alarm, and has no unacknowledged active alarm, the name of that alarm group flashes purple in the banner. 4) An acknowledged latched active activ e alarm is displayed with a steady purple background in the alarm list and in the specific alarm group. Once all of the alarms in an alarm group are acknowledged, the name of that alarm group ceases to appear in the banner. 5) An inactive alarm is only displayed displayed in the specific specific alarm group display. The alarm text is not highlighted. PUSHBUTTON


ACTION The alarms in a specific alarm group can be acknowledged by pressing the ‘acknowledge’ button in the specific alarm group display. This will have the visual effect of stopping all alarms from flashing, and removing the name of the alarm group from the banner. All alarms can be acknowledged by pressing the ‘acknowledge’ button in the alarm list display. The audible alarm begins to sound when an alarm becomes active. The alarms in a group can be silenced by pressing either the ‘Silence alarms’ button, or the ‘Acknowledge alarms’ button in the alarm display for that group. This will not silence the audible alarm if there are active alarms in other groups that have not been silenced. If either the ‘Silence alarms’ button or the ‘Acknowledge alarms’ button is pressed in the alarms list display, all alarms will be silenced and the audible alarm will stop. Once all the alarms in a group have been silenced - the silence button will be greyed out. The latched active alarms in a specific alarm group can be cleared by pressing ‘clear’ in the specific alarm group display. This will clear both acknowledged and unacknowledged latched active alarms. This will have the visual effect of removing the alarm from the alarm list display. This will also have the visual effect of removing the purple background from the cleared alarms in the specific alarm group displays. Active alarms cannot be cleared from the application. The ‘clear’ functionality is similar to t he ‘accept’ functionality in the ‘3 alarm state’ configuration.

Single Line Fly-By Dialogs

Typical Fly-By Dialog Display The single line fly-by dialog displays commands and values relating to the power object that the mouse pointer is currently currently above. Use ‘view’ menu option ‘single line fly-by dialogs’ to toggle single line fly-by mode on and off. When the mode is on, moving the mouse across a power object in a single line diagram will display a dialog box containing commands and values relating to that power object (if available). The configuration decides the commands and values that appear with an object. If the mode is off, information/commands relating to an object can still be accessed by right-clicking on the object. Use the buttons in the dialog to invoke commands relating to a particular object. If you are not already logged in at a security level appropriate to issuing the command, you will be prompted to do so. You will also be asked to confirm the command operation. If single-line fly-by mode is on - a ‘lock’ button will appear in the fly-by dialog box. Press this to prevent the dialog box from disappearing when the mouse leaves the object. When pressed, the text on the ‘lock’ button will change to ‘unlock’ - press the ‘unlock’ button to allow the dialog to disappear when the mouse moves away from an object. If single-line fly-by mode is off, the fly-by dialog can be accessed by right-clicking on a power object - in this mode, the ‘lock’ button is replaced by an ‘exit’ button - use this to close the dialog box. Only one single-line flyby dialog is displayed at a time - this is to reduce the chance of a command being issued for the wrong power object. 3.3.4

Logging Into A Session (Password Operation) Any function of t he HMI which affects the system requires a user to be l ogged on to enable the action to be carried out. A user can log on directly to a session or will be prompted to log on by attempting to perform an action while not already logged on. PRISMIC has four standard user levels. These are Operator / Technician / Supervisor and Commissioning Engineer. The system may be configured with alternative names for ‘operator’, ‘technician’ and ‘supervisor - to apply to the job-titles within the organisation. The login dialog gives a choice of user-levels to login at. The user-level required for an action is determined at the configuration stage.

Login Box Selected For Operator User Level The user-class that the user-level belongs to is listed in brackets after the user-level (unless the user-class description is the same as the user-level - in this case, only the user-level is listed). There are 5 user-classes: - Commissioning Engineer, Supervisor, Technician, Operator and Viewer. Once logged in at a user-level, the user can perform any operation that requires access at that user-level without having to login again. After a period of inactivity, the application automatically logs out the user. The length of this period is defined in the configuration.

Confirmation Confirmation Box Note: All actions have a confirmation box which must be accepted before the operation is carried out 3.3.5

m) New Trend Display Display This option will create a new Trend Display. The user can configure the variables to trend. All registers displayed on the HMI can be trended these are logged to a file on the HMI. A new sample is taken every 6 seconds. The user can view/add/change/delete trends from any of the register types on the HMI (HR, DI, DO, AI and HBit).

From the Trend Editor it is possible to configure more than one variable on a trend display. Two vertical scales can be displayed at the same time. These can also be configured in the editor.

Also the minimum/maximu minimum/maximum/scale m/scale increment increment and plot colour colour values for the operator operator can configure each trend variable within a multitrend. The trend display can be scaled in fixed increments to show between 1 minute and 1 day of trend data. The data for the day can be viewed using the scroll bar in the trend display window. The trend values are recorded even when the display of the trend window is not open or visible. Trend data is automatically saved to disk every day. Historical data from previous days can be displayed by selecting the required date from the pulldown menu on the trend display.

(The trend data is stored in directory “Trends” beneath the configuration directory. Within the “Trends” directory - there is a directory for each day for which trending is active. Within this directory is a file for each variable that is trended). 3.4.6

Commands

The 'commands' menu allows you to send commands to the PRISMIC system. The commands that are available from the command menu are determined by the configuration of your system. A password is required required when when a command menu option option is selected. 3.4.7

Flash Memory Control When PRISMIC is switched on it copies the FLASH values into working memory stores. If, however, the FLASH data memory has been corrupted, PRISMIC copies default values into working memory stores. These values are set during the initial configuration. When presets are changed, the operator should use the ‘Write non-volatile Memory’ facility to make sure that new preset values are stored in FLASH memory and will thus be restored after the next power down. a) Write Flash This option allows the user to write parameters which have been altered into non-volatile FLASH memory. b) Load Default Presets This option allows the user t o re-install the initial configuration presets presets into working memory. This will create a mi smatch with the FLASH memory. c) Load Default Priority Table This option allows the user to re-install the initial configuration Priority Table into working memory. This will create a mismatch with t he FLASH memory. d) Load Default Duty Table This option allows the user to re-install the initial configuration Duty Table into working memory. This will create a mismatch with t he FLASH memory.

3.4.8

Presets

These three menus allow you to view or edit operator/technician or supervisor presets. The lists of options that appear under each of these menus are defined by configuration data. Your system may be configured with alternative names for ‘operator’, ‘technician’ and ‘supervisor’ - to apply to the job-titles within your organisation. All presets require require a password password to alter them.

Using HMI Wit With h Hot Standby PMS (Optional Dual Redundant Microsystem Microsystem)) A single PC can be used to view and interact with two identical PRISMIC systems. This is facilitated by a multi-drop feature of the Modbus protocol. This would typically be selected using a DIP switch within the PRISMIC microsystem allowing the software in the hot standby system to remain identical to the main system. For HMI to see the hot standby PRISMIC microsystem at its Modbus address it is necessary to use the command line switch /SlaveOffset32. As with many Windows application, it is possible to run more than one instance of HMI at any particular time, on the same machine. Thus with a hot standby PRISMIC, an extra instance of HMI would be started with the /SlaveOffset32 command line switch. To toggle between views of the duplicate PRISMIC systems [Alt][Tab] is used to toggle between the two instances of HMI.

EVENT LOGGING APPLICATIO APPLICATION N The following is based on version 1.6 of the Event Logging application.

4.1

A Windows application a pplication runs on the HMI processor processor for sequentially sequentially logging and time stamping PMS. This application creates a daily log file for analysis as required and is independent of the HMI software Introduction The event logger has the following features: A graphical Windows based front-end. • •

•

Events are displayed as they occur.

•

Previous logs can be viewed from the logger.

•

Events can be filtered by type and/or by register number.

•

Events can be sorted.

•

•

•

4.2

Three types of PRISMIC event are displayed by t he logger - digital input changes, changes, digital output changes and text messages.

The logger can run as a standalone application or can run as a server - broadcasting events over a network, or can run as a client - receiving events over a network. The logger can be set to be always on top of other windows - the logger is also fully sizeable, and scrollable - allowing it to be flexibly positioned. The contents of a log can be exported to a CSV file.

The rest of this document explains these features in more detail Online/Offline Option Click on the ‘Online’ checkbox to toggle between online and offline mode.

When the application is online - events will be displayed as and when they occur. Events cannot be sorted or exported when the application is online. Historical logs cannot be viewed when the application is online. All event filtering is active whether the application is online or offline.

When the application is offline, you can select to view or delete historical logs. A new log is created each time the event logger is started, or when the PC clock passes midnight. Unlike the online log, a historical log can be sorted or exported. There is an entry titled ‘[Online snapshot]’ in the historical log selection list. Select this to view a copy of the online log just before the log was taken offline. The online snapshot can be sorted or exported in the same manner as other historical logs. 4.3

Sorting The entries in a log can be sorted by clicking on the various column headings. Click once on a heading to sort the entries in an ascending order. order. Click Cli ck again to sort t he entries in a descending order. To sort the log entries using more than one column, click on the ‘Advanced Sort’ button and then select the columns to sort by. For example, if you wanted to view log entries sorted primarily by register, and then by date stamp for entries with the same register number - select Register in the top selection box, select ‘event time stamp’ in the second selection box - then click button ‘Do Sort’.

Sorting is only available when the logger is offline - although an online snapshot can be sorted. 4.4

Filtering Event log entries can be filtered to exclude unwanted log entries. The filtering works whether or not the log is online or offline. To select filter options, click on button ‘Select Event Log Filters’. Records can be filtered by type, and/or by register range. For example, to filter out all text messages, and all event log messages relating to register 100 and registers 110 to 120 do the following:

•

Untick the ‘Include text messag m essages’ es’ checkbox.

•

Enter 100 in the leftmost edit box and click add.

•

Enter 110 in the leftmost edit box, and 120 in the rightmost edit box and click add.

•

Click the ‘Do Filter’ button.

This will immediately filter the list of log entries. If a different list of log entries is selected - the filter acts on these as well. The filtering information is saved between log sessions - so if the event logger is restarted - the filters from the previous session will still be in force.

4.5

Notes: 1) You can filter filt er unrecognised log messages. These are messages that cannot be recognised as text, or digital input/output events due to some corruption. 2) The filtering process does does not discard discard the filtered log entries - if all filtering is turned turned off - all entries will reappear in the list. Exporting The content of the log list can be exported to a comma separated variable (csv) file. To do this, click the ‘export’ button - and select a file to store the export file in. This file can be read by most spreadsheet packages. The exported file also contains details of the filters that were in effect when the log was exported. You cannot export when the log is online, although you can take the application offline and export the online snapshot.

4.6

View options Click on the ‘always on top’ check box - to position the event logger window on top of all other windows. The event logger is fully sizeable and scrollable. The view options can be used to position the event logger over another application - for example, the PRISMIC HMInt application.

4.7

Settings Click on the Settings button to change the mode of operation for the event logger. The application can run in one of 3 modes: 1) Standalone Mode: Mode: The application receives events from the serial port and displays them in the event logger. 2) Server Mode: Mode: The application receives events from the serial port and broadcasts them across the network. When in server mode, the application also acts as a client - and receives and displays the events that it broadcast. For this reason, the event logger will not work in server mode if it is not networked - in this case use Standalone mode. 3) Client Mode: Mode: The application receives events broadcast across a network from an event logger in server mode. The event logger locates the server using the server connection string as specified in the settings dialog. The application has been been tested as a client across a network - the connection string used in this case is the computer name. In theory, the event logger could connect across the internet. The logs are saved to files exclusively on the server. To be able to view these logs in the historical file list from a client application, you need to specify the server event log directory in the settings dialog box. If this is not specified, you will not be able to view historical logs from the client application. It may be the case that the server event log directory is not visible from the client - hence specifying this path is optional. Changes to settings do not take effect until the application is restarted.

4.8

Configuration Configuratio n Information The application reads configuration information from the directory specified by registry entry ‘HKEY_LOCAL_MACHINES\SOFTWARE\Brush Electrical Machines Ltd.\Config Path. The PRISMIC HMI also gets its configuration information from this directory. This information includes serial port settings and digital register texts. The event logs are stored in directory ‘EventLogs’ beneath this directory.

4.9

Troubleshooting 1) If nothing appears in the log - check the following: Are the filters t hat you have defined filtering out all log entries? •

PS-PT Power And VAr Transducer Card An STE bus 8 channel card for measurement measurement of active or reactive power power flow in an electric power generation system. The card performs real time multiplication of a current and voltage waveform to produce a value representing instantaneous power for each channel. This uses two input signals; one derived from a single phase current transformer (CT) and another derived from a three phase voltage transformer (VT). The CT derived signal used for input to the PS-PT card is actually a voltage across a 50m Ω shunt resistor through which a CT secondary current is passing. The PI-CTPT interface unit provides this shunt resistor. The VT derived signal needs to be transformed for input to the PS-PT card so that it represents either "in-phase" voltage or "quadrature" voltage. This transformation is achieved using a PIVTPT voltage m onitor transformer. transformer. It should be noted that this circuit board does not provide signal isolation. Isolation is provided by the PI-VTPT unit and isolating current transformers located within the PMS panel. The PS-PT is fitted with a gain potentiometer, accessible via the front panel, for each channel. Offset adjustments are made directly in the software via the STE bus. Nominal max CT current is switch selectable to the follow f ollowing ing values: 1.25A, 1 A 750mA, 500mA. 500mA. The isolating CTs within the PMS panel are used to ensure that plant monitoring CT signals are transformed to an appropriate level to match one of these switch settings. Card format is double Eurocard with front panel. STE bus interface uses the bottom (P2) connector. Plant connections use the top (P1) connector.

Recommendations Recommendati ons For Plant And Power Supply Wiri Wiring ng Plant interfacing wiring should be brought through the gland plate in the base of the panel and connected to the terminal block as shown in the contract drawings. Power supply cables should be connected directly to the EMC filt er located close to the gland plate.

The cables used for plant interfacing and power supply should take the form of armoured multicores of at least 1.0 mm2 with insulation rating of at least 600V. A higher insulation rating may be necessary depending upon the site conditions. All appropriate wiring regulations should be followed.

The multicores should be grouped by signal type and the armour should be bonded to the body of the panel using suitable cable glands. 5.2.12

TESTING AND COMPLETION

6.1

Factory Acceptance Tests

Issue: A

Date: 08 March 2006

Page: 50 of 51

The tests comprise two separate independent verifications that will be performed at times suitable to the respective delivery of panel and software: •

•

The power management system software functional factory acceptance test will be carried out using software-based simulation of the power system at Brush site in Loughborough. This will cover the HMI display, communications and control functionality. The panel factory acceptance test will be carried out separately at panel manufacturing location. This will cover the hardware interface between the PMS rack I/O, conditioning equipment and the terminals. An HMI will be used in commissioning mode to monitor inputs and drive outputs.

The customer’s representative will sign the approval document on successful completion of each of the factory acceptance tests. 6.2

DCS Interface Test This test is to be carried out at Brush site during or after the PMS FAT. If this cannot be coincidental with the FAT or is at the DCS manufacturer’s site then the testing may utilise PRISMIC PMS simulation equipment in place of the contract hardware. Off site testing may be subject to an additional cost.

6.3

Packaging And Preservation Packaging suitable for road or rail transportation and as under deck cargo in accordance with BS 1133 will be provided. Packaging is not suitable for long term storage.
