配电网故障定位算法研究综述

A survey of fault location algorithms in distribution network

电力系统通过配电网与电力用户相连,快速准确的配电网故障定位技术是提高供电可靠性的必然要求。目前,针对配电网故障定位技术的研究已经有了很多成果,结合国内外学者对配电网故障定位技术研究的成果,对配电网故障定位算法进行了综述。根据配电网故障定位的方式不同,主要从两方面进行阐述,一是传统测距方法,二是配电网自动化故障定位方法。并着重分析了配电网故障定位的经典算法,包括算法的基本原理及其优缺点。结合现有配电网故障定位技术的研究成果和社会对供电可靠性的需求,对未来配电网故障定位技术的研究进行了初步展望。

The power system is connected to the power users through the distribution network.The fault location technology of distribution network is necessary to improve the reliability of power supply.At present,a lot of achievements have been made in the research on fault location technology of distribution network.According to the different fault location methods of the distribution network,mainly from two aspects:one is the traditional distance measurement method,the other is the distribution network automation fault location method.The classical fault location algorithm of distribution network is analyzed emphatically,including its basic principle,advantages and disadvantages.Combined with the research results of the existing distribution network fault location technology and the demand of the society for power supply reliability,the study of the future distribution network fault location technology is preliminarily prospected.
