摘　　要：针对传统保护方案不能满足分布式电源接入后配电网继电保护要求的问题,提出了一种基于信息物理融合系统(CPS)思想的多源配电网区域保护方案。方案以CPS保护终端为界将配电网分区,与同一区域关联的CPS终端通过通讯网络共享信息,使每个终端都能获得关联区域边界处的运行参数;嵌入在CPS终端中的计算机程序实时处理获得的信息,判断故障是否在关联区域的内部发生,从而实现区域的保护。The traditional protection scheme can not meet the requirements of relay protection in distribution network due to the penetration of distributed generators.Based on the ideas of the CPS（Cyber Physical System）,an area protection scheme for distribution network with distributed generators is proposed in the paper.The distribution network is split into several areas by CPS protection terminals.The terminals associated with the same area exchange information through the communication network so that each terminal can get related area＇s operating parameter at boundaries.The computer program which is embedded in terminals deals with the obtained information in real time and decides whether fault has happened in the area,so as to implement protection for distribution network.
