DS200TCTGG1AFF GE MKV, Turbine Trip Board

Description:

DS200TCTG  Turbine Trip Board
The Turbine Trip Board (TCTG), in location four of the <P1> core, is used to operate fuel shutoff valves for the turbine. Two types of trip relays are available on the TCTG board for failsafe fuel valve operation. There are primary trip relays (PTRs) and emergency trip relays (ETRs). Communication faults and the CSP operate the PTRs. The TCEA boards in the <P1> core operate the ETRs, which conduct a 2/3 vote for an emergency trip. Hardwire trip pushbuttons will de-energize the 24 V dc supply to both the PTR and ETR relays and initiate a trip. The synchronizing relays are also located on the TCTG board.
TCTG Connectors
J7W  Distributes the 125 V dc power from the TCPD board in the <PD> core.
JDR  Reads the PTR trip signals from the TCQA board in the <R1> core, relays K10, 13, 16, and 19. Reads synchronize commands from the TCQA board in the <R1> core. Reads the generator and bus signals from the PTBA board . JDR, JDS and JDT are all daisy chain connected on the TCTG board.
JDS  Reads the PTR trip signals from the TCQA board in the <R1> core, relays K11, 14, 17, and 20. Reads synchronize commands from the TCQA board in the <R1> core. Reads the generator and bus signals from the PTBA board . JDR, JDS and JDT are all daisy chain connected on the TCTG board.
JDT  Reads the PTR trip signals from the TCQA board in the <R1> core, relays K12, 15, 18, and 21. Reads synchronize commands from the TCQA board in the <R1> core. Reads the generator and bus signals from the PTBA board . JDR, JDS and JDT are all daisy chain connected on the TCTG board.
JLX  Reads the ETR trip signals from <X> in the <P1> core. ETR relays K5 and K8 are fed by the JLX connector. Supplies the 24 V dc protective bus.
JLY  Reads the ETR trip signals from <Y> of the <P1> core. ETR relays K4 and K7 are fed by the JLY connector. Supplies the 24 V dc protective bus.
JLZ  Reads the ETR trip signals from <Z> of the <P1> core. ETR relays K6 and K9 are fed by the JLZ connector. Supplies the 24 V dc protective bus.
JN  Reads and writes signals to the PTBA terminal board in the <P1> core. These signals include the breaker close signal, hardwire trip signals, and the alarm horn signal.
JM  Reads and writes signals to the PTBA terminal board in the <P1> core. These signals include the breaker close signal and the emergency trip signals.
JT  Typically not used.
The hardware document in Appendix B and the signal flow diagrams in Appendix D contain more information.

TCTG Configuration
Hardware. There is one hardware jumper on the TCTG board. J1 is the Emergency Overspeed servo Clamp Enable jumper for servo valves one through four. This jumper is used to apply 24 V dc to the servo outputs. The actual relay is located on the TCQC board. Refer to Appendix A for information on the hardware jumper setting for this board.
Software. There is no software configuration done on the TCTG board.
TCTG ETR Relay Circuit
The TCEA boards <X>, <Y> and <Z> in the <P1> core generate the trip signals for the ETR relays. The signals are written to the TCTG board via the JLX/Y/Z connectors. The ETR relays perform a hardware level two out of three vote to determine if the unit should be tripped. If two out of three relays call for a trip, by opening and closing a series of related contacts on the TCTG board, the unit will trip. Signals that will trip the ETR relays are high pressure shaft overspeed and rapid deceleration, low pressure shaft overspeed and rapid deceleration and cross trip. The trip signals are then written to the PTBA terminal board via the JM connectortion.
