- Anti-Interference Design: Built with high anti-interference capabilities to maintain stable operation in electrically noisy industrial environments.
Application Scenarios
Extensively used in power plants for controlling gas and steam turbines, industrial automation for precise mechanical drive speed regulation, marine engineering for ship propulsion engines, and oil and gas drilling platforms.
Performance Parameters
- Control Accuracy: Maintains extremely tight speed droop and isochronous control parameters.
- Reliability: Engineered for continuous duty in critical infrastructure with high mean time between failures (MTBF).
Material Composition
Features industrial-grade printed circuit boards with protective conformal coatings, housed in a ruggedized metal chassis.
Structural Characteristics
- Panel Mount / Rack Mount: Designed for secure mounting within standard industrial control cabinets.
- Terminal Blocks: Robust rear terminal connections for secure field wiring.
Working Principle
The controller monitors the engine or turbine speed via magnetic pickup units (MPUs). It compares the actual speed to the setpoint and calculates the necessary fuel or steam valve adjustment. In parallel operations, it communicates with other controllers to proportionally share the electrical or mechanical load.
Installation Requirements
- Clearance: Maintain adequate clearance around the module for ventilation and heat dissipation.
- Signal Wiring: Speed sensor cables must be shielded and routed away from high-voltage power cables to prevent signal noise.
Usage Precautions
- Software Configuration: Use the designated Woodward configuration software via the RS-232 port to set up control parameters accurately.
- Firmware Updates: Ensure the controller is running the latest approved firmware to maintain optimal performance and safety features.
