2.4

Generic applications

Controller performs individual steps like: • Gen-set start • GCB dead bus closing • Synchronizing • Load control mode • Reverse synchronizing • Gen-set stop Steps are driven by commands from an external device, e.g. PLC. This device is responsible for all sequencing (steps order). Typical applications: • Complex systems with several buses where PLC controls each step of the gen-set. • Complex CHP applications controlled from a central PLC

Description without MGCB • •

When BI Sys start/stop closes, sets are starting with a delay SysAMFstrtDel. The first set with a correct voltage and frequency closes the GCB to the dead bus, others are synchronized. When the relay BI Sys start/stop is opened, all GCBs are opened at the same time with a delay SysAMFstopDel.

Description with MGCB • •

• •

When BI Sys start/stop closes, sets are starting with a delay SysAMFstrtDel. The first set with a correct voltage and frequency closes the GCB to the dead bus, others are synchronized. BI Load res 2 is controlled by MGCB to differentiate the load reserve necessary before closing of MGCB (setpoints LoadRes Strt 2 and LoadRes Stp 2), and operational load reserve while the system is loaded (setpoints LoadRes Strt 1 and LoadRes Stp 1).Typically before MGCB closing the higher reserve is needed to absorb the full load. Once loaded, the load reserve can be reduced to e.g. level of the biggest single consumer. MGCB is closed by BO Syst res 1 OK of any running genset and then held by MGCB feedback. When the relay BI Sys start/stop is opened, all GCBs are opened at the same time with a delay SysAMFstopDel. Loss of voltage at the bus opens MGCB.

The Uf↑↓ relay opens MCB after the mains fails. At the same time the Uf↑↓ relay closes BI Sys start/stop and the sets are starting with a delay SysAMFstrtDel. It is similar to setpoint EmergStart del in SPtM application. The first set with a correct voltage and frequency closes the GCB to the dead bus, others are synchronized. When the mains returns, Uf↑↓ relay opens BI Sys start/stop and all GCBs are opened at the same time with SysAMFstopDel delay. It is similar to setpoint Mains Ret del in SPtM application. Bus 3 phase voltage relay detects no voltage and with its time delay closes MCB

It is similar to setpoint EmergStart del in SPtM application. The first set with a correct voltage and frequency closes the GCB to the dead bus, others are synchronized. BI Load res 2 is controlled by MGCB to differentiate the load reserve necessary before closing of MGCB (setpoints LoadRes Strt 2 and LoadRes Stp 2), and operational load reserve while the system is loaded (setpoints LoadRes Strt 1 and LoadRes Stp 1).Typically before MGCB closing the higher reserve is needed to absorb the full load. Once loaded, the load reserve can be reduced to e.g. level of the biggest single consumer. MGCB is closed by BO Syst res 1 OK of any running genset and then held by MGCB feedback. When the mains returns, Uf↑↓ relay opens BI Sys start/stop and all GCBs are opened at the same time with SysAMFstopDel delay. It is similar to setpoint Mains Ret del in SPtM application. Loss of voltage at the bus opens MGCB. Bus 3 phase voltage relay detects no voltage and with its time delay closes MCB

Hint: Setpoint SysAMFstrt del is used for engines start delay after the mains fails. It is similar to setpoint EmergStart del in Single Stand-by. Setpoint SysAMFstp del is used for GCB opening after the mains returns. Single Stand-by.

The IM-NT controller closes binary output Sys start/stop which is connected to Sys start/stop inputs of the gen-set controllers if: a) If IM-NT binary input Rem start/stop gets active (AUT mode only). b) If AMF condition is sensed in IM-NT and the gen-set group should be started as stand-by power source (AUT mode only). c) If PeakShaving function senses that it is suitable to start the gen-set group in order to lower the mains import (AUT mode only). d) If Start button is pressed on IM-NT front panel or remotely (MAN mode only). The signal can be deactivated by pressing the Stop button. If the controller is switched from AUT to MAN mode, the internal status of the flip-flop circuit created by Start-Stop buttons is set to follow the previous state in AUT mode. E.g. if the gen-set group has run in an AMF situation in AUT mode, switching to MAN will not stop it (= Sys start/stop output stays active). After binary input Sys start/stop closes the gen-sets are starting with a delay SysAMFstrtDel. It is similar to setpoint EmergStart del in SPtM application. The first set with a correct voltage and frequency closes the GCB to the dead bus, others are synchronized. When the mains returns, IM-NT synchronizes gen-sets to the mains with limitations given by setpoints ProcessControl:ParallelEnable and Synchro enable (see Table on p.7 in IM-NT-MCBMGCB-X.X.pdf).

Hint: It is possible to use virtual shared inputs/outputs to connect for example Sys start/stop output from IM-NT to corresponding binary input of all controllers instead of hardwiring it. See chapter Shared virtual I/O periphery. PeakShaving function should be used in order to lower the mains import (AUT mode only).

PeakShaving settings: PeakLevelStart: PeakLevelStop: PeakAutS/S del:

PeakLevelStop to 32000 kW 0 to PeakLevelStart kW 1-3200 s. Function is active only for PeakAutS/S del <> OFF.

If PeakLevelStart is reached for PeakAutS/S del time then the IM-NT controller closes binary output Sys start/stop which is connected to Sys start/stop inputs of the gen-set. Sys start/stop is deactivated after PeakLevelStop is reached for PeakAutS/S del. Hint: The Peak start/stop function activates the common output signal Sys start/stop in IM-NT. The signal is intended to be directly connected to Sys start/stop inputs of all gen-set controllers in the system, e.g. using SHBIN/SHBOUT peripherals.

Integrated PLC

The NT family controllers contain a virtual PLC module that can be “connected” to the system. The activation of the PLC is done in the Modules card in GenConfig. Depending on the controller HW type, a different number of functions and function types is available. See the table below for complete overview. The internal PLC can simplify or even avoid the external logic in a switchboard, bringing another level of control system integration. The PLC has analog and binary inputs and outputs that can be interfaced to any suitable controller analog value, physical or logical binary input and output.

PID works when binary input GATE is not configured. Sensor fail on measured (or requested) value set PID output to Input bias and blocks PID calculation. There is configurable LoLimit (for 0V or 0mA output) and HiLimit (10VDC or 20mA) for analog output configuration.

Binary output is activated when counter is over limit. Output stays closed even if counter overflow over maximum 65535. Counter contains binary Reset input (level sensitive) that set counter to zero, resets binary output and blocks counting when active. Maximal counter value is 65535 (16 bites wide) and continues to zero. The minimal pulse period is 0,2 sec (max 5 Hz) - in this case the counter overflow after 218 minutes.

Binary output changes state with period given by analog Input reload val [ 0,1s ] when Binary input Run is closed and Binary input Reload is opened. Timer starts with low state period when selection Firs down is ticked. E.g. Output changes state each 10 sec when input value is 100. Timer reloads (accepts period change) in the end of period or when binary input Reload is closed. Reload function can be useful when very long time period is running.

Note Binary input. (IN) Delay of rising edge in 0,1s (Tup) Delay of falling edge in 0,1s (Tdown) Binary input to reset output. (RESET) Binary output. (OUT)

This module allows to create own output pulse, which is derived from an input pulse by a delay of its rising/falling or the both edges. With using of delay block, a condition Tup < Tdown + TIN has to be fulfilled. Note: output pulse is not generated if condition Tup < Tdown + TIN is not fulfilled. The function can be used as a noise filter – it does not accept an input pulse shorter than 100 ms.

PHYSICAL BINARY INPUTS

The controller features many logical outputs, i.e. outputs that could be configured to physical outputs (terminals of the controller itself or of expansion modules). But sometimes it is necessary to bring the output signal back to the input, if a special behaviour is required. E.g. logical binary output Batt volt is linked with only a Warning type alarm, and from some reason it is required that the engine be stopped in this case (at certain site). You can achieve this by bringing the signal to physical output and then connect it to a physical input. Then this input can be configured with a Shutdown type protection. The disadvantage of the above solution is that you are losing one input and one output of the controller / expansion module, which is costly. The virtual periphery simulates this within the controller, bringing a group of “physical outputs”, linked with a group of “physical inputs”. So you can configure a logical output of the controller to this module, and then configure a protection (or a link to logical input) to the “physical input“ part of the module, as you would do with real inputs. The same can be done with PLC I/O, so e.g. a complex evaluation of a protection in PLC can be brought directly to an input configured for this protection type.

INTERNAL LINK IN CONTROLLER

4.3

Shared virtual I/O periphery

It is often required that certain signals be brought to all controllers in the group. For example MCB feedback, System Start/Stop, Common Shutdown signal etc. These are all binary signals. Sometimes analog signals are required as well, like engine room temperature signal, where too high temperature can cause the nominal power of all gen-sets in the room to be reduced (power derating function). IG/IS-NT controllers have a provision to make it easier when designing such an application. These controllers have a sophisticated system of shared virtual modules, where one controller is a signal server and the other controllers are recipients of this signal. The signals are distributed via the CAN bus which typically interconnects all the controllers on one site.

Configuration These virtual modules can be added / removed like any other HW module in GenConfig / card Modules. Then they appear in the list of inputs or outputs in the card I/O.

SHBOUT/SHAOUT modules They behave like standard output modules, but the signals assigned to them don’t appear on any physical output, instead of that are distributed via the CAN bus to other controllers. Each module has 8 outputs.


53

ShBIN/SHAIN modules They behave like standard input modules, i.e. you can assign any logical input signal that is available in the controller to them, or configure a protection based on their activity. Each module has 8 inputs.

SHBOUT + SHBIN modules There are four channels (i.e. 4 groups of 8 binary inputs/outputs) available for binary signal sharing. Each channel can have its source (SHBOUT module) in different controller. All other controllers can be configured as the recipients of this channel (SHBIN module).

TARGET (SHBIN) Intercontroller CAN bus

SOURCE (SHBOUT)

TARGET (SHBIN)

Hint: If more controllers are selected to be the source for one channel, only the controller with the lowest CAN address is taken into account, and all controllers report a “SHBinCfgErr” message in Alarmlist.

The picture below shows the principle of the SHBOUT module. It can distribute the forwarded states of physical binary inputs, or some signals created inside the controller’s FW or PLC:

In this particular example, the SYSTEM START signal which should command the start / stop for all the controllers on the site, is transferred from the terminal (physical binary input) to the SHBOUT module.

All other controllers on the site should be configured in the way that the signal is picked up in the same position (1-8) where it has been assigned to in SHBOUT module. The signal is then picked up from the module and can be used by the controller’s FW or PLC like any other physical binary input:


54

Together looks like this:

SHAOUT + SHAIN modules There is one channel (i.e. 1 group of 8 analog inputs/outputs) available for analog signal sharing. The channel can have its source (SHAOUT module) only in one controller. All other controllers can be configured as the recipients of this channel (SHAIN module).

Hint: If more controllers are selected to be the source for the analog channel, only the controller with the lowest CAN address is taken into account, and all controllers report a “SHAinCfgErr” message in Alarmlist.

The picture below shows the principle of the SHAOUT module. It can distribute the forwarded values of externally measured (physical) analog inputs, as well as the values measured or computed inside the controller’s FW or PLC:

All other controllers on the site should be configured in the way that the value is picked up in the same position (1-8) where it has been assigned to in SHAOUT module. The value is then picked up from the module and can be used by the controller’s FW or PLC like any other physical analog input:

5. Controller configuration tricks Force value Force value feature enables a Binary input to switch between two different values of a setpoint:

BI: Force value Opened Closed

Nominal power 100 kW 200 kW

Or between (FV) setpoint and Analog input (or in general any value):

BI: Force value Opened Closed

Hint: If Force value is active, it is not possible to change setpoint value (e.g. from InteliMonitor). Force value has to be deactivated first. Configure Force value in GenConfig.
