Woodward 9907-173
Product Name: Multi-Unit Parallel Dynamic Load Sharing Control Module
Detailed Product Introduction: High-performance analog load balance control module from Woodward 9907 series. It collects real-time three-phase voltage and current signals of each parallel generator set, calculates actual output power dynamically, outputs precise torque bias adjustment signals to each prime mover governor, realizes proportional equal load distribution among multiple units, and stabilizes grid frequency and operation state.
