摘要
柔性互联配电网的拓扑结构复杂、故障波及范围广泛,为了准确捕捉故障信息,研究多分支柔性互联配电网故障自动定位方法.基于分布式行波检测技术判定柔性互联配电网的故障线路,根据不同故障线路上的行波传播特性,分别计算主干线路和分支线路上故障点到检测点的距离,完成故障区段的自动定位.结果表明,设计方法下故障测距误差仅0.77%,具有较高的定位精度.
Abstract
The topology structure of flexible interconnected distribution networks is complex and the fault range is wide.In order to accurately capture fault information,a multi-branch flexible interconnected distribution network fault automatic positioning method is studied.Based on distributed traveling wave detection technology,fault lines in flexible interconnected distribution networks are determined.According to the propagation characteristics of traveling waves on different fault lines,the distance from the fault point to the detection point on the main line and branch line is calculated,and the automatic positioning of the fault section is completed.The results show that the fault distance measurement error under the design method is only 0.77%,which has a high positioning accuracy.
