Core Functions

1. Precision speed & load control, supporting isochronous control, droop control, synchronization and grid‑parallel operation

2. Multi‑stage actuator/valve control for steam/gas inlet regulation, single‑extraction and admission control for turbines

3. Critical speed avoidance, valve position limit, startup/shutdown sequence control

4. Real‑time monitoring, self‑diagnosis, fault alarm and protection functions

5. Remote speed/load setting via 4‑20 mA analog signal

6. Parameter configuration & monitoring via Woodward dedicated software and Ethernet/serial communication
