摘要

分布式发电系统的接入改变了配电系统的故障电流分布以及原有配电网保护配置的基础条件

对配电网系统相间短路保护设备可能造成影响。文中详细分析了不同重合闸方式下

分布式电源的接入对配电系统保护协调性所产生的各种可能的影响

给出了各种情况下消除分布式电源的接入对配电网保护设备影响的判断条件。

Abstract

Distributed generation connected to distribution system changes the direction of shortfaultcurrent. As a result

the operating conditions of distribution protection system become different. How to keep existing protection system well and connect as large distributed generation as we can to distribution system is the chief problem. This paper analyzes the effect of distributed generation connected to distribution system on protection and gives the criterion of how to avoid the effect.
