Functional Description

DS200TCTGG1ADC is a Turbine Trip Board developed by GE. It is a part of Mark V control system. Designed to ensure turbine safety by facilitating controlled trip functions. It includes Primary Trip Relays (PTRs), triggered by control sequence programs and communication faults, and Emergency Trip Relays (ETRs), activated when TCEA boards X, Y, and Z in the P1 core vote for an emergency trip.

Features

• Primary Trip Relays (PTRs) are triggered by control sequence programs and communication faults to safely shut down the turbine when required.
• Emergency Trip Relays (ETRs) are activated when TCEA boards X, Y, and Z in the P1 core vote for an emergency trip, ensuring an immediate shutdown in critical situations.
• If a hardwired trip occurs, it de-energizes the 24V DC power supply to both PTR and ETR relays, initiating a turbine trip.
• The TCTG board also includes synchronizing relays, ensuring the generator and turbine operate in sync with the power grid.

Connector

• J7W distributes 125V DC power from the TCPD board in the PD core.
• JDR, JDS, JDT are daisy-chained connectors that read PTR trip signals from the TCQA board in the R1 core and synchronize commands from the PTBA board.
• JLX, JLY, JLZ read ETR trip signals from cores X, Y, and Z in the P1 core, feeding the 24V DC protective bus.
• JN reads and writes signals to the PTBA board, including breaker close signals, hardwired trip signals, and alarm horn signals.
• JM reads and writes breaker close and emergency trip signals to the PTBA board.
• JT is typically not used.

Hardware Configuration

• The board has one hardware jumper (J1) used for enabling the Emergency Overspeed Servo Clamp.
• J1 applies 24V DC to servo outputs 1-4, ensuring the overspeed protection mechanism is engaged when required.
• The actual relay controlling this function is located on the TCQC board.

Frequently Asked Questions

What is DS200TCTGG1ADC?
It is a Turbine Trip Board developed by GE under the Mark V series.

What is the function of the PTR and ETR relays?
PTR relays initiate turbine trips based on communication faults and control sequence programs, while ETR relays trigger emergency trips when the TCEA boards in cores X, Y, and Z vote for a shutdown.

How does the board handle emergency trip functions?
The board de-energizes the 24V DC supply to both PTR and ETR relays when a hardwired trip occurs, ensuring immediate turbine shutdown in critical situations.

What is the purpose of the J1 hardware jumper?
J1 is used for enabling the Emergency Overspeed Servo Clamp, which applies 24V DC to servo outputs 1-4 for emergency trip conditions.
