Main Features and Advantages
Precise excitation regulation: GE IS200ECTBG1ADE adopts an advanced PID control algorithm with feedforward compensation, achieving excitation current regulation accuracy of ±0.5% full scale. This ensures the generator maintains stable terminal voltage even under sudden load changes, reducing voltage fluctuations and improving grid compatibility—critical for renewable energy integration scenarios.
Comprehensive fault protection: GE IS200ECTBG1ADE monitors key parameters such as excitation current, temperature, and power supply status in real time, triggering fast-response protection actions (e.g., current limiting, shutdown) when abnormalities occur. The built-in fault logging function records event details with time stamps, enabling maintenance personnel to quickly diagnose and resolve issues, minimizing unplanned downtime.
Seamless system integration: As a native module of GE’s Mark VIe platform, GE IS200ECTBG1ADE connects effortlessly with Mark VIe controllers and HMIs without additional adapters. Support for Ethernet/IP and Modbus RTU protocols also facilitates communication with third-party SCADA systems, enhancing flexibility for multi-vendor industrial environments and simplifying centralized monitoring.
Application Fields
In thermal power plants, GE IS200ECTBG1ADE serves as the core excitation control module for coal-fired and gas-fired generator sets, regulating the excitation current of 10MW to 100MW synchronous generators. It ensures stable voltage output during load changes, improving the efficiency of power generation and reducing the risk of grid frequency fluctuations caused by generator instability.
Industrial cogeneration systems rely on GE IS200ECTBG1ADE to control the excitation of on-site generator sets, which supply both electricity and heat for manufacturing processes. In petrochemical plants and refineries, for example, it maintains consistent generator output to power critical equipment like compressors and pumps, ensuring uninterrupted production while optimizing energy utilization.
The product also excels in marine power systems, where it controls the excitation of shipboard generators, adapting to the dynamic load changes caused by navigation equipment and cargo handling operations. Additionally, GE IS200ECTBG1ADE is used in renewable energy supporting systems, such as wind and solar power plants, to regulate the excitation of backup generators, ensuring stable power supply during intermittent renewable energy output.
