中文摘要: 利用ETAP软件建立了仿真模型,针对分布式电源的容量和接入位置等因素,探讨了分布式电源对配电网短路电流分布和继电保护的影响.结果表明:分布式电源会影响配电网中的电流保护以及自动装置的正常工作,引起保护误动或拒动,使保护失去选择性.

中文关键词: 分布式电源配电网继电保护短路电流

Abstract:With ETAP software，distribution system model and DG model are built and the currentprotection is calculated． On the basis of the size and location of DG the effects on the short circuitcurrent and protection of distribution system． The result shows the DG will influence the normaloperation of current protection and automatic device，such as misoperation or rejected move，leadingto the lose of selectivity．

keywords: DG distribution network relay protection short circuit current
