摘　　要：配网线路运行环境复杂,事故多发,且发生故障后排查效率低,巡线工作量大,故障排查时间长。针对此问题,开发出一种配电线路故障精确定位系统,通过在线监测线路故障工频以及行波的方式快速准确定位故障位置。The operation environment of distribution network line is complex, accidents occur frequently, and the troubleshooting efficiency is low after faults occur. The workload of line patrol is large and the troubleshooting time is long. To solve this problem, a distribution network hidden danger early warning and fault location system is developed. The fault location can be quickly and accurately located by on-line monitoring of line fault power frequency and traveling wave.
