摘　　要：随着分布式电源越来越多地接入电网,含储能系统的微电网与配电网继电保护配置的问题也更加突出,目前国内、外均还在探讨之中。结合一个微电网实际工程的应用,详细分析了并网和离网模式下配电网和微电网内部的故障特性。利用实时数字仿真系统(RTDS)搭建半实物仿真平台进行仿真分析,应用仿真结果,详细阐述了继电保护配置方法,对微电网的推广应用具有指导意义。With more and more distributed generations （DG） connecting into power grid, the problem of micro-grid with energy storage system and distribution network protection configuration is also more prominent, which are still being discussed at home and abroad. With the actual application of a micro-grid project, this paper analyzes the failure characteristics of distribution network and the internal micro-grid in the grid and off-grid mode. Real-time digital simulation system （RTDS） is used to build semi-physical simulation platform for simulation analysis, and the relay protection configuration method is elaborated with the simulation results, which has the guiding significance to the use of micro-grid.
