Core Functions

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

2. Automatic synchronization: matches frequency, phase and voltage precisely via analog/discrete bias signals for grid connection

3. High‑precision PID closed‑loop speed/load control, supports critical speed avoidance, valve stroke limit and startup protection

4. Real‑time self‑diagnosis, overspeed monitoring and multi‑channel relay alarm output

5. 4‑20 mA / 1‑5 VDC remote setpoint input, compatible with upper‑level DCS/PLC system linkage

6. Independent RS‑232 & RS‑422 communication ports, supports online parameter tuning and real‑time monitoring via dedicated Woodward software
