The Technique of the Optimization Applied in the Grounding Grid’s Failure Diagnosis of the Power Plant and Substation

应用电网络和矩阵理论建立故障诊断方程 ,在地网故障诊断应用能量最低原理和优化技术等学科 ,解决了欠定方程的求解问题 ;算例分析验证了该方法的正确性。

This thesis has studied fault diagnosis of grounding grid in the power plants and substations. The theory of the electric network and the matrix theory are applied to establish the diagnostic equation, therefore it can effectively resolve the problem of morbid equation by introducing the lowest energy theory and the technique of optimization. Meanwhilie by means of the analysis of the example, the correctness, feasibility and practicality of the method have been verified.
