The GE US IS200VTURH1BAC turbine control board is a module specifically designed for turbine control. Its main functions and features can be summarized as follows:

1、 Basic Information

Brand and Manufacturer: GE (General Electric Company)

Model: IS200VTURH1BAC

Application: Steam turbine control system

2、 Main functions

Overspeed protection:

Monitor and measure the turbine speed to generate the primary overspeed trip signal. This is one of the core functions of the control board, aimed at ensuring that the turbine operates within a safe speed range.

Control the three main overspeed trip relays on the TRPx terminal board. Once an overspeed condition is detected, the emergency solenoid valve will be immediately triggered to protect the turbine from damage.

Shaft current/voltage monitoring:

Monitor the voltage and current induced by the axis and issue an alarm when the level is too high. This helps prevent electrical faults and mechanical damage, ensuring the stable operation of the turbine.

Flame detector monitoring:

In gas turbine applications, the control board can also monitor eight Geiger Mueller flame detectors. These detectors are used to detect the flame state in the combustion chamber, ensuring the stability and safety of the combustion process.

Generator synchronization and circuit breaker control:

The bus and generator voltage on this board will be automatically synchronized with the turbine controller and excitation system. At the same time, it also allows for the control of the generator synchronous relay and the main circuit breaker relay coil to achieve precise synchronization of the generator and accurate control of the circuit breaker.

Modular and redundant design:

IS200VTURH1BAC supports triple modular redundancy (TMR) or simplex applications. In TMR systems, it can provide higher reliability and fault tolerance; In a simplex system, it can meet basic control requirements.

3、 Technical features

Highly integrated: This control board integrates multiple sensors, relays, and controllers to achieve comprehensive monitoring and control of various parameters of the turbine.

Accurate measurement: High precision sensors and measurement circuits are used to ensure accurate measurement of turbine speed and shaft current/voltage.

Quick response: When an abnormal situation is detected, it can quickly generate a trip signal and trigger corresponding protective measures to prevent further damage to the turbine.

Easy to maintain: The modular design makes maintenance and component replacement more convenient and efficient.

4、 Application Fields

The IS200VTURH1BAC turbine control board is widely used in turbine control systems in industries such as power, petrochemicals, and metallurgy. In these fields, it plays a crucial role in ensuring the safe, stable, and efficient operation of turbines.
