应用线路监测分析系统降低故障定位时间的探讨

Research on the Application of Line Monitoring and Analysis System to Reduce the Time of Fault Location

摘要: 肇庆广宁供电局地处山区，管理面积2459平方公里，公用线路71回；其中10 kV山地架空配电线路53回，10 kV平地架空配电线路8回，10 kV电缆配电线路10回；10 kV山地架空配电线路数量多，故障定位难度高、工作量大、时间长，与有限人手和日益提高的线路安全运行水平、供电可靠性需求之间矛盾越发突出。通过搭建10 kV配电线路状态监测分析及故障定位系统，对有效降低线路故障定位之间，提升线路复电时间，确保供电可靠性具有非常重要的意义。

Abstract: Zhaoqing Guangning located in the mountain area, managing an area of 2459 km² which has 71 public line back. Its public line includes 53, 10 kV mountain overhead distribution lines, 8, 10 kV flat overhead distribution lines, and 10, 10 kV cable distribution lines. There are a large number of 10 kV distribution lines on the mountains, which operated with large workload, long time. It’s too difficult to locate the fault of lines. At the same time, Co. manpower, higher level of lines safe opera-tion, the demand of reliable power supply increases much contradiction. By setting up the 10 kV distribution line state monitoring and fault location system to effectively reduce the location of line fault, improve the time of line restoration, and ensure the reliability of power supply.
