Woodward 9907-252
Product Name: Multi-Unit Parallel Load Sharing & Torque Bias Control Module
Detailed Product Introduction: This is a professional analog load balance control module for multi-generator parallel operation systems. It collects real-time three-phase current and voltage signals of each generator set, calculates actual output load power in real time, outputs precise torque bias adjustment signals to each prime mover governor, realizes equal proportional load distribution among multiple parallel units, prevents individual unit overload, idle load operation and unstable grid frequency fluctuation, and greatly improves the stability and economy of parallel power grids.
