Description
GE IS200ESYSH2A
Technical Specifications:
- Brand: General Electric (GE)
- Model: IS200ESYSH2A
- Product Type: Exciter Synchronization Interface Board
- System Integration: Mark VI Speedtronic Platform
Functional Features:
- Grid Matching: Continuously compares generator voltage, frequency, and phase angle with the grid parameters.
- Closed-Loop Control: Adjusts excitation levels dynamically to maintain synchronization and support grid voltage.
- Diagnostic Feedback: Provides real-time status and fault codes to the main HMI for predictive maintenance.
Application Scenarios:
Deployed in thermal, hydro, and combined-cycle power plants for generator excitation control and grid interconnection.
Performance Parameters:
- Reliability: High MTBF (Mean Time Between Failures) designed for continuous 24/7 power generation.
- Signal Fidelity: Low-noise analog inputs for highly accurate phase detection.
Material Composition:
Gold-plated edge connectors for corrosion resistance, multi-layer PCB with controlled impedance traces, and industrial-grade conformal coating.
Structural Characteristics:
Standard 6U or custom Mark VI board size with front panel diagnostic LEDs, test jacks, and rear high-density connectors.
Working Principle:
Utilizes zero-crossing detection and digital signal processing to measure the slip frequency between the generator and the grid, outputting precise thyristor firing pulses to achieve lock-in.
Installation Requirements:
Insert into the correct VME or proprietary backplane slot. Verify that all ribbon cables and discrete wiring are properly seated and locked.
Usage Precautions:
Do not attempt to repair internal components; return to certified GE repair facilities. Ensure the control room environment is climate-controlled to prevent condensation.
