1、 电网故障行波定位网络设计 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

2、故障后,行波定位装置将故障记录单元和 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 DESIGN ABSTRACT With the increasing size of power

3、 systems, power structures become more complex, the traditional method of Traveling Wave Fault Location Fault Location System will not meet the stability and economy requirements. Therefore, the high voltage transmission line fault fast and precise positioning of new technologies and new methods of

4、foreign technology workers has become widespread attention. This paper designs a more reasonable traveling wave fault location of the network, and completed the preliminary design of the software and verify its reliability and practicability. Core part of the article is also part of key technologies

5、 Traveling Wave Fault Location and network design software design. Zhuzhou power network design is to proceed on the existing grid, and therefore the whole system was a more reasonable analysis and fault location network design, and through the ATP / EMTP simulation analysis and verification; Based

6、on network of fault positioning software design, main is in determine system fault Hou, line wave positioning device will fault records unit and GPS clock unit records of line wave data and the time information by General group radio business (GPRS) network Shang to fault positioning host, fault positioning host for fault points calculation, and database of storage and query and fault information of publishing, real implementation has Dang any a Taiwan device occurs fault or started failure,
