摘　　要：近年来国内网都在积极规划和建设智能电网,而智能电网中配电线路故障定位一直是个研究的热点和难点。其中故障定位的方法有很多,本文主要针对配电网中故障指示器定位的准确性一直没有得到有效的解决,从而设计了一套故障定位算法以及故障定位程序。该算法根据故障指示器定位的原理以及云南电网实际线路情况,通过建立了配电网网拓扑模型,采用逻辑位置标示和故障事件集的概念,通过逻辑分析从而得出故障位置,并且判断故障类型。其中故障事件由多条遥信抽象出来,目前该故障定位算法已应用在云南电网配电线路故障监测系统主站中,通过实际现象表明,该算法和程序在不影响线路正常工作的前提下,能够准确地定位出故障发生的位置,并能准确判断故障类型。该方法原理简单,定位准确度高,成本较低,易于推广。In recent years,both at home and abroad are actively planning and construction of smart grid,and smart grid distribution line fault location has been a hot and difficult research.There are many methods of fault location,and the accuracy of fault location in distribution network has not been effectively solved,and a fault location algorithm and fault location program are designed.Based on the principle of fault indicator location and the actual line condition of Yunnan power grid,this algorithm establishes the topology model of distribution network,uses the concept of logical location mark and fault event set,and obtains the fault location by logical analysis and judges the fault type.The failure event is abstracted by a number of remote signals.At present,the fault location algorithm has been applied in the main station of the fault monitoring system of Yunnan power distribution line.Through the actual phenomenon,the algorithm and the program do not affect the normal work of the line,Can accurately locate the location of the fault,and can accurately determine the type of failure.The method has the advantages of simple principle,high positioning accuracy,low cost and easy to popularize.
