A wind-electric set control system includes the center controller PLC, the intermediate relay panel, the soft merge network control panel, the display operation panel and the connector. The center controller PLC mainly includes CPU module 315-2DP, digital input module DI, digital output module D0, high-speed counter module FM350-2, analog input module AI, communication module CP340; the intermediate relay panel comprises a number of DC coil relays. The intermediate relay panel and the soft merge network control plane respectively connect with the input and output modules of the center controller PLC, and connect with the controlled object through connector. The system uses the intermediate relay panel to isolate the input/output signal, which improves the resist interference ability of the system. The soft merge network control uses current-limit soft-cut-in control strategy, to make the merge network processing more stable. This invention limits the merge network number of the small motor ...
