The hardware structure of the IED of a BC is described. Next, the paper discusses the communication mode of the current Integrated Substation Automation Systems(ISA) and describes the hardware structre and the functions of the ISA with fieldbus. At last the paper presents trends in the development of ISA.展开更多
