Application solution of high-voltage measurement and control unit in smart substation

An application solution is presented for the mono-configured bay-level measurement and control unit in smart substation since the dual-configured HV process-level intelligent devices are required to access it simultaneously.The measurement and control unit designed based on the measurement and control platform adopts the HW-SW collaboration of multiple CPUs,including the SV treatment of AC sampling,GOOSE input /output,synchronization function and the bay-level interlocking.It applies two identical front-end modules to respectively pre-process the data from the dual-configured devices,which are merged in their master CPU module according to configuration strategy.The designed bay-level measurement and control unit is applied in a 500 kV smart substation project and the practice shows its feasibility.
