随着行波定位装置应用的电压等级越来越低,低电压等级电网的站、线数量多,拓扑结构复杂,如何经济、合理地配置行波定位装置,实现故障定位的全网覆盖,具有重要意义。在行波网络定位算法的基础上,提出了一种网络分解的行波定位装置优化配置方法。该方法通过分析每个变电站与故障线路的连接关系,用简单网络代替原网络中复杂的连接关系,求出各条故障线路下的有效变电站,最终获得全网行波定位装置配置方案。在此基础上,以每退出一套装置导致的网络定位算法失效的线路长度,决定所有装置的安装顺序,并以某输电网络为例,验证了所提算法的可行性及有效性。

As the application of the traveling wave fault location device’ s voltage grade becomes lower and lower, and there are many stations and lines of the low voltage grade power grid as well as the complex topology structure, it is of great significance to install traveling wave fault location device economically and reasonably, and realize the entire network coverage of the fault location. Based on the traveling wave network localization algorithm, this thesis propose an optimal configuration method of network decomposition’ s traveling wave pos...
