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 MKIV board size.
- Connectors: High-density connectors for actuator and feedback wiring.
Working Principle
Receives position commands from the MKIV 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 MKIV 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.
