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 TCTG 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 TCTG board.

TCTG GENERATOR BREAKER CLOSE CIRCUIT:

The signals to close the generator breaker originate on the STCA board in and in the TCEA boards in the 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 core performs a synchronizing permissive (synch check) calculation and also sends a permissive to close the breaker. The automatic synchronize signals are two out of three voted on the TCTG board. If two out of three automatic synch signals and the synch check signal have been given by , 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.

TCTG 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 TCTG 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 .4.s. 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:

How does redundancy contribute to the reliability of a GT/TMR Turbine Simplex Trip Board?

Redundancy ensures that if one component of the trip board fails, there are backup components ready to take over seamlessly. This redundancy significantly reduces the risk of system failure and ensures continuous protection and control of the turbine.

How does a GT/TMR Turbine Simplex Trip Board work?

The GT/TMR Turbine Simplex Trip Board employs advanced algorithms and redundant architecture to continuously monitor critical parameters such as turbine speed, temperature, pressure, and vibration.

How are boards packaged for shipment from WOC?

Parts are placed in antistatic packets and securely packed in ESD boxes cushioned with ESD Foam designed to safeguard electrical components.
