Yingpai Intelligent Digital Automatic Parallel Connection System adopts the PLC ( programmable logic controller ) of the DSE7510 & DSE8610 Intelligent Parallel Generating Set made by Deep Sea Electronics plc (DSE) as the logic control device to control the generating sets and the synchroswitching-in and parallel connection of the low-voltage switches of the output GCB ( Generator Circuit Breaker). It is capable of automatically controlling the startup & close-down, parallel and separating brakes of the diesel engine through internal control program and corresponding external control signal and according to the program-set control logic automatically. It can also actualize the power distribution to multiple sets and the synchronous parallel connection inspection. It combines the functions of load distribution, synchronous control, set control into one, having complete functions of sets control, monitoring and protection.
