含DG配电网故障测距技术综述

A Review of Fault Location Technology in Distribution Network with DG

分布式电源(DG)的接入对配电网的潮流分布、短路特性和保护运行具有重大影响,配电网故障精确测距特别是含DG配电网的故障测距到目前都没有切实有效和适用性强的方法。本文对配电线路尤其是含DG配电网的故障测距方法进行了归纳和总结,在简单介绍传统配电系统测距方法的基础上,重点分析了国内外比较先进的含DG配电系统故障测距技术,并对含DG配电网故障精确测距技术进行了展望。

The aeeess of the distributed generations （DGS） has great impacts on Ihe flow distribution, the short eirct, it characteristics and the proteelton operation of the distribution network. At present, there are no effective or applicable methods to precisely locate the fault in distribution network, especially in the distribution network with DGS. This paper summarizes the methods of the faith location in distribution network, especially in distribution network with DGS. On the basis of a brief introduetion of the fauh location methods in the traditional distribution system, the paper mainly analyzes the domestic and fon-ign advanced fault location teehniqt, es. Finally, it presents a prospect of the precise fauh location in distribution Network wilh DGs.
