摘要
介绍了电力系统线路故障点判断常用的保护动作分析、故障录波器分析和雷电定位系统三种方法。通过对这三种方法进行比较，举例说明了要快速、准确地判断故障点应当三种方法同时考虑。并提出故障录波器应装有ＧＰＳ钟，使故障录波器的时间与雷电定位的时间相对应。为了电网安全运行，还没配置故障录波器的１１０ ｋＶ枢纽变电站均应考虑配置故障录波器。
This paper describes .and compares three popularly used trouble locating methods of power lines, i. e., protection action analysis, fault recorder analysis and lightning location system. It is illustrated that the three methods should be combined to achieve rapid and exact trouble locating results. The fault recorder should be equipped with GPS clock to reconcile its time with that of lightning location system, and all 110 kV load-center substations should be provided with fault recorders for the safety of power network.
