含分布式电源的配电网保护技术及研究现状

Research of Adaptive Protection for Distribution Network with Distributed Generation

分布式电（distributed generation，DG）的接入改变了传统的配电网故障特性，使传统的配电网的保护方式发生了巨大变化。本文综述了几种常见的含分布式电源的配电网保护方法，介绍其优缺点，并介绍了一种新的保护原理——基于故障分量的自适应保护新方法。

Distributed generation （DG） access has changed the traditional distribution network fail to bring to the traditional distribution network distributed power distribution network introduced a new protection principle component protection can not be ignored. This paper reviews several common protection methods, introduced its advdnt＇ages and disadvantages, and of the protection of the new method - based on adaptive fault
