摘要
随着用户对电力能源需求的不断增加,电网建设不断加强,而10 kV配网是电网的重要部分,对保证供电安全有重要作用。基于此,研究10 kV配网线路故障定位方法。划分10 kV配网线路故障区域,在大面积线路中提取可能出现故障的范围;构建配网线路故障定位模型,缩小配网线路故障范围,进而实现配网线路故障的精准定位;采用对比实验的方式,验证新定位方法的定位精准度更高,极具推广价值。
With the increasing demand of users for power energy,the construction of power grid is also being strengthened.The 10 kV distribution network is an important part of the power grid and plays an important role in ensuring power supply security.Based on this,the fault location method of 10 kV distribution network is studied.The fault area of the 10 kV distribution network line is divided,and the possible fault range in the large-area line is extracted.The model of distribution line fault location is built,the scope of distribution line fault is reduced,and then the accurate location of distribution line fault is achieved.By means of comparative experiments,it is verified that the positioning accuracy of the new positioning method is higher,which is of great promotion value.
