含分布式电源的配电网继电保护方案研究综述

Research summary of relay protection scheme for distribution nework with distributed generation

分布式电源接入配电网之后,对原有的配网保护产生了很大的影响,本文从影响重合闸、潮流方向、短路电流、孤岛运行等四个方面进行了总结分析,综述了国内外主要的一些含分布式电源的配网继电保护措施以及各自的一些优缺点,对于进一步的方案改进有一定的意义。

After the distribution network connected to the distribution network, it has a great influence on the protection of the distribution network. The effects of the four aspects, such as the influence of the coincidence gate, the current direction, the short circuit current and the isolated island operation, are summarized and analyzed in this paper. Summary the relay protection measures and some advantages and disadvantages of the distribution network with distributed generation. It has a certain significance for further improvement of the program.
