FUNCTIONAL DESCRIPTION:

DS200TCTGG1ACA is a GT/TMR Simplex Trip Board manufactured and designed by General Electric as part of the Mark V LM Series used in GE Speedtronic Turbine Control Systems. The GT/TMR Simplex Trip Board (TCTG), located in the core, is used to trip the turbine. The TCTGG1ACA board supports two different types of trip relays. There are two types of trip relays: primary (PTR) and emergency (ETR). The communication failures and control sequence program initiate PTR trips, while the TCEA boards, and in the core vote for an emergency trip, resulting in ETR excursions. Hardwire trips de-energize the 24-volt supply to both the PTR and ETR relays, triggering a trip. The synchronizing relays are also found on the TCTGG1ACA board.

TCTGG1ACA GENERATOR BREAKER CLOSE CIRCUIT:

The signals to close the generator breaker originate on the STCA board in R1 and in the TCEA boards in the P1 core. The TCEA boards use the PT signals from the PTBA terminal board to perform the automatically synchronized calculations and to send the permissive signal to close the breaker. At the same time, the STCA board in the R1 core performs a synchronizing permissive (synch check) calculation and also sends a permissive to close the breaker. The automatically synchronized signals are two out of three voted on the TCTGG1ACA board. If two out of three automatic synch signals and the synch check signal have been given by R1, then the TCTG board gives the permissive to close the breaker. The K1, K2, and K3 relays will send the breaker close signal to the PTBA board via the JN and JM connectors.

TCTGG1ACA MANUAL AND EXTERNAL TRIP CIRCUIT:

Normally closed contact inputs can be hardwired into the PTBA terminal board to initiate a trip when the contacts are opened. Emergency stop buttons are an example of this. These signals are read by the JN connector and written to the TCTGG1ACA board, where they trip the K22, 23, 24, and 25 relays. These relays are referred to as the .4.s. about an ANSI standard device number for the Master Protective. When the 4s are tripped, they de-energize the 24 V dc protective bus used by the PTR and ETR relays, causing them to initiate a trip. The TCEA board typically monitors the hardwire trip signals 1 through 3 for an emergency stop and will record their event back to the Control Engine.

FREQUENTLY ASKED QUESTIONS:

What is the DS200TCTGG1ACA?

The DS200TCTGG1ACA is a GT/TMR Simplex Trip Board designed for GE Speedtronic Mark V LM turbine control systems. It is a critical component responsible for safely tripping the turbine under various conditions, including control sequence errors and emergency events. The board ensures reliable turbine protection and integrates seamlessly with other Speedtronic components.

Which types of trip relays does the board support?

This board supports Primary Trip Relays (PTR) for standard trips and Emergency Trip Relays (ETR) for critical shutdowns. PTRs are activated by communication failures or control logic, while ETRs respond to emergency conditions identified by the TCEA boards. Together, they provide comprehensive protection for the turbine.

How does the board handle manual or external trip signals?

Manual or external trips, such as emergency stop buttons, can be hardwired into the PTBA terminal board. These signals are transmitted to the TCTGG1ACA, which then activates relays K22–K25 to de-energize the 24 V DC protective bus. This action triggers both PTR and ETR relays to trip the turbine safely.
