Description
GE IS200EXHSG4A
Technical Specifications:
- Brand: General Electric (GE)
- Model: IS200EXHSG4A
- Product Type: Exciter Synchronization Interface Board
- System Integration: GE Speedtronic Mark VI
Functional Features:
- Phase Matching: Continuously monitors and adjusts the phase angle between the generator exciter and the grid.
- Voltage Regulation: Interfaces with the Automatic Voltage Regulator (AVR) to maintain stable grid voltage during synchronization.
- Fault Protection: Detects out-of-phase closing conditions and blocks breaker closure to prevent catastrophic damage.
Application Scenarios:
Critical component in synchronous generators, steam turbines, and gas turbines within utility and industrial power generation facilities.
Performance Parameters:
- Synchronization Accuracy: Microsecond-level phase detection for zero-transient grid connection.
- Processing Speed: Ultra-fast signal processing to accommodate rapid grid frequency fluctuations.
Material Composition:
High-grade analog components, precision resistors, and gold-plated connector pins for reliable signal transmission in harsh electrical environments.
Structural Characteristics:
Standard Mark VI board size with front panel test jacks, status LEDs, and rear high-density connectors for clean cabinet wiring.
Working Principle:
Samples generator and grid voltages, calculates the slip frequency and phase difference, and outputs precise firing pulses to the exciter thyristor bridge to achieve lock-in.
Installation Requirements:
Must be installed in the designated exciter control slot. Ensure all shielded signal cables are properly grounded at the board end.
Usage Precautions:
Never bypass synchronization checks. Always verify the health of the exciter system before attempting a manual or automatic sync.
