PRS-3201-B is the main unit of the coordination control device, featuring functions such as AGC, AVC, primary frequency regulation, dynamic voltage regulation, inertia response, and source-grid-load-storage control.
The PRS-3201M acquisition unit is a standard 4U full-layer device for PRS-3201-B power control. It supports GOOSE access for energy storage PCS, three-level expansion, dual-machine hot-standby functionality, and the collection of AC quantities for three bays.
The PRS-3201S acquisition unit is a standard 4U half-layer device for PRS-3201-B power control. It supports GOOSE access for energy storage PCS, three-level expansion, dual-machine hot-standby functionality, and the collection of AC quantities for one bay.
The analog circuit uses high-precision, wide-range components without hardware amplitude/phase adjustment circuits. With 16-bit high-resolution AD sampling and software algorithms, the circuit is simple, reliable, and free from zero drift.
