1、电网故障行波设计定位网络摘要随着电力系统规模日益扩大，电网结构愈加复杂，传统故障行波定位方法将无法满足系统故障定位稳定性和经济性的要求。因此，高压输电线路故障点的快速、精确定位新技术与新方法研究已成为国内外科技工作者广泛关注的热点。本文设计了一个较为合理的行波故障定位的网络,并完成了软件的初步设计,并验证了其可靠性和实用性。文章的主要内容也是关键技术部分就是故障行波定位的网络设计及其软件设计。网络设计是在株洲电网现有的网架上着手的，故对整个系统进行了较为合理的分析和故障定位网络设计，并通过 ATP/EMTP 进行了仿真分析和验证；基于网络的故障定位软件设计，主要是在确定系统故障后,行波定位装置
2、将故障记录单元和 GPS 时钟单元记录的行波数据及时间信息通过通用分组无线电业务(GPRS) 网络上传到故障定位主机,故障定位主机进行故障点计算、数据库的存储和查询以及故障信息的发布等，真正实现了当任意一台装置发生故障或启动失灵，都可以根据其他变电站的记录数据可靠定位，有效的提高了定位结果的精度和可靠性。关键词：故障测距； GPS 时钟； GPRS ； 网络定位； ATP/EMTP 仿真分析 TRAVELING WAVE FAULT LOCATION NETWORK DESIGNABSTRACTWith the increasing size of power systems, power s
