Woodward 9906-620
Dedicated generator set parallel operation load sharing control module, applied to multiple diesel and gas generator sets parallel grid-connected system. It collects the active power and reactive power signal of each unit in real time, realizes automatic average load distribution among parallel units through internal high-precision calculation and regulation algorithm. The module supports droop control and isochronous control mode, with communication isolation and signal anti-crosstalk design, ensure stable load sharing of multiple units without circulation current, simplify on-site parallel system debugging and operation maintenance.
