GE IS200VTURH2B Primary Turbine Protection Board

GE IS200VTURH2B Primary Turbine Protection Board

The IS200VTURH2B is a Primary Turbine Protection Board, manufactured and designed by General Electric as part of Mark VI Series used in gas turbine control system.

The Primary Turbine Protection (VTUR) board, has the following functions: 

• Measures the turbine speed with four passive pulse rate devices and passes the signal to the controller, which generates the primary overspeed trip 

• Provides automatic generator synchronizing and closes the main breaker 

• Monitors induced shaft voltage and current 

• Monitors eight Geiger-Mueller® flame detectors on gas turbine applications. The detectors connect to TRPG and use 335 V dc, 0.5 mA from an external supply. 

• Controls three primary overspeed trip relays on the TRPx terminal board. The controller generates the trip signal, which is sent to VTUR and then to TRPx to trip the emergency solenoids. The turbine overspeed trip can come from VTUR or VPRO. TRPx contains nine magnetic relays to interface with three trip solenoids, known as the electrical trip devices (ETD). Nine relays are used in TMR systems, three in simplex systems.

Operation

In simplex applications, up to four pulse rate signals can be used to measure turbine speed. Generator and bus voltages are brought into VTUR for automatic synchronizing in conjunction with the turbine controller and excitation system. TTUR has permissive generator synchronizing relays and controls the main breaker relay coil 52G. Shaft voltage is picked up with brushes and monitored along with the current to the machine case.
