Core Functions

1. Dual control modes: isochronous mode for standalone genset constant‑speed operation; droop mode for multi‑unit parallel load sharing

2. Precise PID closed‑loop speed control, supporting critical speed avoidance, valve stroke limit and startup protection

3. Independent overspeed protection module, real‑time speed monitoring, self‑diagnosis and multi‑channel alarm output

4. 4‑20 mA analog remote setpoint input, compatible with upper‑level DCS/PLC system linkage

5. Automatic synchronization, deceleration control, fuel limiting and auxiliary interlock protection functions

6. Parameter configuration, online tuning and real‑time monitoring via dedicated Woodward configuration software
