摘　　要：为解决传统变电所接地故障诊断方法中诊断幅值低的问题,基于电网络和矩阵理论设计变电所接地故障诊断方法。基于电网络,采集、处理变电所接地故障数据,提取离散型变电所接地故障信号,计算故障信号特征能量;基于矩阵理论,建立故障诊断矩阵,上传故障诊断数据,实现故障诊断定位。实例分析结果表明,本文设计的故障诊断方法能解决传统变电所接地故障诊断方法中诊断幅值低的问题。In order to solve the problem of low diagnosis amplitude in traditional substation grounding fault diagnosis methods,a substation grounding fault diagnosis method was designed based on electrical network and matrix theory.Based on the electric network,the grounding fault data of substation is collected and processed,the discrete grounding fault signal of substation is extracted,and the characteristic energy of fault signal is calculated;Based on the matrix theory,the fault diagnosis matrix is established,the fault diagnosis data is uploaded,and the fault diagnosis location is realized.The results show that the fault diagnosis method designed in this paper can solve the problem of low diagnosis amplitude in traditional substation grounding fault diagnosis methods.
