GE Fanuc IS200TSVCH2AED MRP246517 Turbine Speed Voltage Control Module
Product Description
The IS200TSVCH2AED MRP246517 is a critical turbine speed voltage control module developed by GE Fanuc, designed specifically for use in gas and steam turbine control systems. As a key component of GE’s Mark VIe or Mark VI turbine control platforms, it specializes in monitoring turbine speed signals and regulating voltage outputs to maintain stable operation of turbine governors, excitation systems, and associated auxiliary equipment. This module is widely applied in power generation (thermal power plants, combined cycle plants), oil and gas (turbine-driven compressors), and industrial processing (turbine-driven pumps), where precise speed control and voltage regulation are essential for turbine efficiency and safety.
In a thermal power plant, the module continuously receives speed feedback signals from turbine-mounted sensors (e.g., magnetic pickups or optical encoders). It processes these signals to calculate real-time turbine speed, then adjusts the output voltage to the governor actuator—modulating fuel flow or steam inlet valves to maintain the turbine at the set speed (e.g., 3000 RPM for 50 Hz power generation). It also regulates voltage supplies to excitation systems, ensuring stable generator output voltage even during load fluctuations. In turbine-driven compressor systems, it prevents overspeed conditions by triggering protective actions (e.g., closing fuel valves) if speed exceeds safe thresholds.
