GE IS200VTURH1BAA IS200VTURH1B Turbine Specific Primary Trip Board

Technical Specifications 

The GE IS200VTURH1BAC is a Turbine Specific Primary Trip Board used in the Mark VI control system. Its functions include turbine speed measurement, primary overspeed protection, generator synchronization, shaft voltage and current monitoring, and primary trip relay control. Four passive pulse-rate devices monitor turbine rotational speed and transmit speed information to the controller. When an overspeed condition is detected, the controller generates a primary trip signal that passes through VTUR to the applicable trip terminal board, allowing the trip system to activate the turbine's electrical trip devices.

Functions

Turbine Speed Measurement and Overspeed Protection: VTUR efficiently measures turbine speed using four passive pulse rate devices. This measured data is relayed to the controller, which generates the primary overspeed trip signal. This safety mechanism acts as a crucial protective measure against potential overspeed conditions.
Automatic Generator Synchronization and Breaker Control: In addition to overspeed protection, VTUR facilitates automatic generator synchronization, ensuring seamless coordination between generator systems. It also manages the closure of the main breaker, enhancing the system's efficiency during operation.
Monitoring of Induced Shaft Voltage and Current: VTUR meticulously monitors induced shaft voltage and current, crucial parameters that provide insights into the operating conditions of the turbine. This monitoring aids in identifying and addressing potential issues to maintain optimal performance.
Control of Primary Overspeed Trip Relays: VTUR plays a key role in controlling three primary overspeed trip relays situated on the TRPG terminal board. The controller generates trip signals, which are then transmitted to VTUR and subsequently to TRPG. This chain of command triggers emergency solenoids, efficiently executing the turbine overspeed trip protocol. Importantly, this trip can originate either from VTUR or VPRO, offering redundancy and reliability in safety protocols.
