Description
GE DS200GSIAG1B
Technical Specifications
- Product Type: Generator Synchronization Interface Board.
- System Compatibility: GE Speedtronic Mark V Turbine Control System.
- Signal Processing: Handles voltage, frequency, and phase angle measurements.
Functional Features
- Grid Synchronization: Accurately measures generator and grid parameters to facilitate safe breaker closing.
- Signal Isolation: Provides robust galvanic isolation to protect sensitive control electronics from grid transients.
- Real-Time Monitoring: Continuously tracks synchronization conditions and reports status to the main controller.
Application Scenarios
- Power Generation: Essential for gas and steam turbine generators connecting to utility grids.
- Island Power Systems: Used in microgrids and captive power plants requiring precise generator-to-load synchronization.
Performance Parameters
- Measurement Accuracy: High-precision voltage and frequency measurement for reliable synchronization.
- Response Time: Millisecond-level processing to meet strict grid interconnection standards.
Material Composition
- Substrate: Multi-layer industrial-grade PCB with gold-plated traces for signal integrity.
- Components: Precision analog ICs, high-speed opto-isolators, and ruggedized discrete components.
Structural Characteristics
- Form Factor: Standard Mark V series board dimensions.
- Connectors: High-density backplane edge connectors and specialized front-panel terminals for grid and generator signals.
Working Principle
The board continuously samples the voltage and frequency of both the generator and the utility grid. It calculates the phase difference and slip frequency, transmitting this data to the Mark V regulator, which then issues the precise close command when all synchronization criteria are met.
Installation Requirements
- Ensure the system is completely isolated from power sources before installation.
- Use properly shielded cables for all grid and generator signal connections to minimize EMI.
- Align the board carefully with the backplane guides during insertion.
Usage Precautions
- Strictly adhere to ESD protocols when handling the board.
- Never disconnect signal cables while the generator is energized.
- Verify calibration settings after any board replacement.
