基于多电源并列运行的输配电网故障诊断的改进方法研究

Research on Improved Fault Diagnosis Method of Transmission and Distribution Network Based on Multi-Power Parallel Operation

为有效定位输配电网的故障区段,提升调度应急处置工作的针对性和有效性,在多电源并列运行故障诊断的矩阵算法基础上,提出了基于网络拆分的故障诊断优化方法。通过多重故障场景测试分析,当存在告警信息畸变时,该方法尽管因广度优先搜索分块会浪费一定的时效性,但其容错性好,可有效解决多重故障诊断的问题。

In order to effectively locate the fault section of the transmission and distribution power grid,improve the pertinence and effectiveness of emergency response work,a fault diagnosis optimization method based on network splitting is proposed on the basis of the matrix algorithm for fault diagnosis of multi-power source parallel operation.Through testing and analysis of multiple fault scenarios,it has been found that although this method wastes a certain amount of time due to breadth first search partitioning when there is distortion in alarm information,it has good fault tolerance and can effectively solve the problem of multiple fault diagnosis.
