配电网分支线断线故障定位过程中,由于故障干扰分支节点识别方法的差异,难以确认断线发生范围,不同采样率下的故障定位结果相对误差较大。因此,提出考虑系统运行方式的配电网分支线断线故障精确定位方法。根据配电网的拓扑结构,分析供电系统内行波传输路径。基于供电系统运行方式,构建配电网分支节点连通矩阵,识别受到断线故障干扰的分支节点,确定断线发生范围,结合断线故障的特征参数,判断故障发生区段,结合零模和线模行波传播时间差,获取故障测距,实现配电网分支线断线故障精确定位。实例分析结果表明:获取精度较高的行波信号波形后,不同采样率下的故障定位结果相对误差降低了48%、12%。
In the process of locating faults caused by branch line breaks in distribution networks
it is difficult to determine the range of wire breakage due to differences in fault interference branch node identification methods. The relative error of fault location results under different sampling rates is relatively large. Therefore
a accurate location method for branch line break faults in distribution networks considering system operation mode was proposed. The traveling wave transmission path within the power supply system was analyzed based on the topology of the distribution network. A connection matrix for branch nodes was constructed in the distribution network based on the operating mode of the power supply system. Identify the branch nodes affected by wire breakage faults and determine the scope of wire breakage occurrence. Determine the fault occurrence interval based on the characteristic parameters of wire breakage faults. By combining the time difference between zero mode traveling wave and line mode traveling wave
fault location can be obtained
achieving precise positioning of branch line breakage faults in distribution networks. The example analysis results show that after obtaining a high-precision traveling wave signal waveform
the relative error of fault localization results at different sampling rates is reduced by 48% and 12%.
