摘要
通过对变电站接地网腐蚀理论的研究,应用电网络理论推导建立故障诊断线性方程,探讨了最优化方法在地网故障诊断中的应用,从而有效地解决了欠定方程的求解问题。同时,通过实验数值计算结果验证了该方法的正确性、可行性和实用性,并讨论了可及节点变化对诊断正确与否的影响。
This thesis has studied the grounding grid fault diagnosis of substations.The theory of the electric network is applied to establish the diagnosis equations.Readers will know how to use technique of optimization to solve the diagnosis equations,therefore it can effectively resolve the problem of morbid equation by introducing the lowest energy theory.Meanwhile,it has been testified the correctness,feasibility and practicality by use of the analysis of experiments.It has also studied the influence of the diagnosis result when the number of touchable nodes is changed.
