The Brayton cycle is characterized by means of two parameters:

NOTE: entropy Entropy is a thermodynamic property that is the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. During this work, entropy accumulates in the system, which then dissipates in the form of waste heat.

In classical thermodynamics, the concept of entropy is defined phenomenologically by the second law of thermodynamics, which states that the entropy of an isolated system always increases or remains constant. 13 13/11/2014


Specific Work means ‘Work per unit of mass’

T

Useful Specific Work is: Wout = Wexp – Wcomp where: Wexp = h3 – h4 = cp ( T3 – T4 ) Wcomp = h2 – h1 = cp ( T2 – T1 )

Moreover, a Gas Turbine works in the following conditions: •

an open cycle, so an assumption must be made about the exhaust gases to be cooled by the atmosphere

•

a combustion chamber in place of the heat exchanger, so the mass flow is not really constant (due to the amount of fuel added), even if its variation can be considered negligible

Ambient Temperature

Tamb ↑ ⇒ Pout ↓

As the compressor inlet temperature increases, the specific compressor work increases and the weight of the delivered air decreases (decreasing of the specific weight). Consequently the turbine efficiency (and usefull work) decreases. 22 13/11/2014


Atmospheric Pressure (Altitude)

Patm ↑ ⇒ Pout ↓

As the compressor inlet pressure increases, the specific compressor work increases and the weight of the delivered air decreases (decreasing of the specific weight). Consequently the turbine output power, that depends on the air specific weight, decreases. 23 13/11/2014


Specific Humidity

Humidity ↑ ⇒ Pout ↓

The air with high umidity rate is less dense than dry air. Consequently the turbine output power, that depends on the air specific weight, decreases. 24 13/11/2014

Turbine and Auxiliaries Gas Turbine review and working principles Power shaft managing

HD single shaft

A classical operating application of single shaft gas turbines is to drive alternators, because in this application there is the need to regulate power at constant rpms (network frequency).

Turbine and Auxiliaries Gas Turbine review and working principles Power shaft managing HD double shaft

Two Shaft Gas Turbines, as MS5002, need only the HP rotor to rotate at constant speed (5100 rpm), while the Power Turbine speed may change responding to load speed needs, by means of variable nozzle partitions.

With variable nozzles in open position, upmost power is used by the HP turbine.

Aeroderivative double shaft

• • • • •

Gas Generator turbine drives axial compressor and turbine auxiliary by means of gearbox. Power Turbine drives load, usually a centrifugal compressor or a pump, not often an electric generator. PT e GG works at different speed. GG and PT speed change during operation according request of Power from load. For this type of engine variable vanes are installed on axial compressor. In this way varying the angle α of this vane it’s possible control the dynamic of fluid of this component avoiding surge and stall a not design speed. Jet Turbines to increase power output on LP need to increase speed of GG. In this way the control of power for jet turbines is obtained simply controlling the fuel 27 13/11/2014

Mark VI – Hardware Simplex – TMR, redundancy and voting process Level of redundancy Simplex systems have only one chain, and are the least expensive. Reliability is average.

Simplex systems in a typical power plant are used for applications requiring normal reliability, such as control of auxiliaries and balance of plant (BOP). A single PLC with local and remote I/O might be used in this application. In a typical Mark VI, many of the I/O are non-critical and are installed and configured as simplex. These simplex I/O boards can be mixed with TMR boards in the same interface module.

TMR systems have a very high reliability, and since the voting software is simple, the amount of software required is reasonable. Input sensors can be triplicated, if required.

Triple Modular Redundant (TMR) control systems, such as Mark VI, are used for the demanding turbine control and protection application. Here the highest reliability ensures the minimum plant downtime due to control problems, since the turbine can continue running even with a failed controller or I/O channel. In a TMR system, failures are detected and annunciated, and can be repaired online. This means the turbine protection system can be relied on to be fully operational, if a turbine problem occurs.

44 13/11/2014

Mark VI – Hardware Simplex – TMR, redundancy and voting process Output processing

Digital output

For normal relay outputs, the three signals feed a voting relay driver, which operates a single relay per signal.

For more critical protective signals, the three signals drive three independent relays with the relay contacts connected in the typical six-contact voting configuration.

45 13/11/2014

Mark VI – Hardware Simplex – TMR, redundancy and voting process Output processing

Analog output (servo)

For servo outputs as shown in the following figure, the three independent current signals drive a three-coil servo actuator, which adds them by magnetic flux summation. Failure of a servo driver is sensed and a deactivating relay contact is opened. 46 13/11/2014

Mark VI – Hardware Simplex – TMR, redundancy and voting process Input processing

This arrangement is used for noncritical, generic I/O, such as monitoring 4-20 mA inputs, contacts, thermocouples, and RTDs.

This configuration is used for sensors with medium to-high reliability. Three such circuits are needed For three sensors. Typical inputs are 4-20 mA inputs, contacts, thermocouples, and RTDs. 47 13/11/2014


Three independent sensors can be brought into the controllers without voting to provide the individual sensor values to the application. Median values can be selected in the controller, if required.

Three sensors, each one fanned and then SIFT-voted. This arrangement provides a high-reliability system for current and contact inputs, and temperature sensors. 48 13/11/2014


Speed inputs to high-reliability applications are brought in as dedicated inputs and then SIFTvoted. The following figure shows the configuration. Inputs such as speed control and overspeed are not fanned so there is a complete separation of inputs with no hardware cross-coupling that could propagate a failure. RTDs, thermocouples, contact inputs, and 4-20 mA signals can also be configured this way.

Mark VI – Hardware VME rack(s) and protection module VME rack cards and relative termination boards

I/O Card overview Most I/O boards are single width VME boards, of similar design and front cabinet, using the same digital signal processor (TMS320C32). The task scheduler operates at a 1 ms and 5 ms rate to support high-speed analog and discrete inputs. The I/O cards synchronize their input scan to complete a cycle before being read by the VCMI card. Each I/O board contains the required sensor characteristic library, for example thermocouple and resistance temperature devices (RTDs) linearization. Bad sensor data and alarm signal levels, both high and low, are detected and alarmed. Certain I/O boards, such as the servo and turbine board, contain special control functions in firmware. This allows loops, such as the valve position control, to run locally instead of in the controller. Using the I/O boards in this way provides fast response for a number of time critical functions. Servo loops, can be performed in the servo board at 200 times per second.

VPRO Turbine Protection Card

The VPRO card manages the TPRO board in order to control the turbine speed and eventually its syncronization with a power generator. (like the VTUR with the TTUR).

The three solenoids related with the trip condition are managed both from the VTUR (through the TRPG) and the VPRO (through the TREG); if just one requests the tripping, it is implemented.

Troubleshooting Alarms Alarm from Cimplicity to Toolbox

Take a note of the Alarm ID: i.e P234 Generate an «Alarm List» report from Toolbox 93 13/11/2014


Search, in the «Alarm list report», the alarm ID of the alarm to troubleshoot i.e. P234

Under «Signal name» the name of the alarm signal is reported: i.e. L63FGL_ALM 94 13/11/2014


Searching the alarm signal is possible to view the logic bloks that manage the alarm, and, as consequence, to understood the possible cause conditions.
