Core Functions

1. High‑precision closed‑loop speed control to maintain stable frequency under load changes

2. Isochronous control for single‑unit operation; droop control for multi‑unit parallel running

3. Grid synchronization, load distribution, remote setpoint via 4‑20 mA / 1‑5 VDC analog signals

4. Integrated overspeed protection, self‑diagnosis and fault alarm outputs

5. Direct drive for standard Woodward fuel actuators and turbine control valves

6. Parameter tuning, commissioning and monitoring by dedicated Woodward software
