摘要
为了避免变电站接地网故障诊断时现场开挖，提出了一种基于磁场分布特性的接地网故障诊断方法，该方法能够区分接地网故障类型并可实现对断裂和腐蚀区域的准确定位.结合曼哈顿距离理论与增大激励电流幅值和频率等物理方法，对接地网导体故障特征进行量化与放大.计算表明：通过研究故障接地网地表磁场分布规律，分析断裂点和辐射点的分布特征可判断故障类型和区域；利用腐蚀和断裂特征值可量化故障特征，增大激励电流的幅值和频率可放大故障特征，提高了诊断的精度和效率.研究结果为变电站接地网故障诊断工作提供了理论参考.
Abstract
In order to avoid on-site excavation during the fault diagnosis of the substation grounding grid
a method of grounding grid fault diagnosis based on magnetic field distribution characteristics is proposed. This method can distinguish the types of grounding grid faults and achieve accurate positioning of fracture and corrosion areas. This method combined with Manhattan distance theory and physical methods such as increasing the amplitude and frequency of excitation current
it can quantify and amplify the grounding grid conductor faults characteristics. The calculations show that the fault type and area can be judged by studying the distribution of the fault grounding grid surface magnetic field and analyzing the distribution characteristics of the fracture points and radiation points; the fault characteristics can be quantified by using the corrosion and fracture characteristic values
and the fault characteristics can be amplified by increasing the amplitude and frequency of the excitation current. These methods can improve the accuracy and efficiency of diagnosis. The research results provide a theoretical reference for the fault diagnosis of the substation grounding grid.
