Description
GE DS200FCGDH1B
Technical Specifications
- Product Type: Drive Control Board.
- System: GE Speedtronic Mark V.
- Revision: B indicating specific hardware/firmware version.
Functional Features
- Actuator Control: Provides precise PWM or analog signals to fuel and steam valve actuators.
- Feedback Processing: Reads LVDT and potentiometer feedback to ensure accurate valve positioning.
- Safety Integration: Interfaces with Mark V safety processors for emergency shutdown.
Application Scenarios
- Gas Turbines: Fuel flow control and load management.
- Steam Turbines: Governor valve control and speed regulation.
Performance Parameters
- Positioning Accuracy: High-resolution feedback processing for precise valve control.
- Response Time: Millisecond-level actuator response for grid stability.
Material Composition
- PCB: High-reliability, multi-layer board with conformal coating.
- Components: Precision analog ICs and high-current driver transistors.
Structural Characteristics
- Form Factor: Standard Mark V board size.
- Connectors: High-density connectors for actuator and feedback wiring.
Working Principle
Receives position commands from the Mark V regulator, compares them with actual feedback signals, and generates drive signals to move the actuator to the exact commanded position, closing the control loop.
Installation Requirements
- Follow Mark V installation manuals for proper board placement.
- Ensure all actuator and feedback cables are properly shielded and grounded.
Usage Precautions
- Never disconnect actuator wiring while the turbine is in operation.
- Perform calibration procedures after any board replacement.
