微电网继电保护中特殊性问题解决方案的探讨
Discussion on Special Problem Solutions for Relay Protection in Microgrid
摘要
Abstract
As the representative of renewable energy,wind/solar grid-connected generator has an emerging deep impact on the distribution system.The domestic and foreign engineering and academic circles pay considerable attention to the research of mi-crogrid.A conclusion is first put forward that the internal short circuit current is provided by micro power supply through the analysis of the microgrid formation way.Then,the microgrid protection faces special problems are put forward too,which are poor selectivity,low sensitivity and easy taking off from the network caused by micro power.Based on the local information and multi-ground information,the microgrid protection research status is inducted and analyzed.The key technology,imple-mentation scheme and further research ideas are discussed for solving the problems faced by microgrid protection.关键词
