摘　　要：分布式电源对于配电网的继电保护装置具有一定的积极影响,但是在实际应用的过程中存在缺陷,因此,需要研究分布式电源对配网继电保护的影响。简述了分布式电源对配电网继电保护现状,并分析了其存在的问题。通过增加控制电流电压难度,及重合闸拉弧失败来分析分布式电源对配网继电保护的影响,提升了整体的保护技术,推动了相关行业的发展。Although distributed generation has a certain positive impact on the relay protection device of distribution network,it also has different degrees of defects in the process of practical application.Therefore,the impact of distributed generation on the relay protection of distribution network is studied.This paper briefly describes the current situation of distributed generation relay protection for distribution network,and analyzes its existing problems.By increasing the difficulty of controlling current and voltage,causing relay protection failure and misoperation,and reclosing arc failure,this paper analyzes the impact of distributed generation on distribution network relay protection,improves the overall protection technology,and promotes the dovelopment of related industries.
