摘　　要：在接地网拓扑简约分层理论的基础上,应用电网络理论和矩阵理论建立了本征接地网层上的故障诊断方程.引入能量最低原理建立数学模型,解决了欠定方程的求解问题.对一个小型接地网的计算分析表明所提方法的正确性和可行性.Based on the theory of grounding grid topology simplification , electric network theory and matrix theory are used to establish the intrinsic grounding grid fault diagnosis equation. The establishment of diagnosis mathematical model with minimum energy theorem successfully solves the problem of morbid equation. Results of calculation and analysis of practical examples show that the propoesed methed is feasible.
