基于分层约简模型的接地网故障诊断软件设计

在文献11]提出的接地网分层约简模型和文献9]提出的多激励迭代最小二乘故障诊断方法的基础上，利用MATLAB完成了一套接地网腐蚀故障诊断的软件设计。详细论述了分层约简模型的自动生成方法、接地网可测性分析的软件实现、不确定支路组及其原形自动分解的软件实现和不确定支路电阻范围估计的软件实现，并以一个60支路的实验接地网为例进行了说明，结果表明提出的方法是可行的。

Software design of grounding grid corrosion diagnosis based on hierarchical simplification of network topology

Based on the hierarchical simplification of grounding grids in11] and the multi-excitation iteration least square diagnosis approach in 9],an application software based on MATLAB of corrosion diagnosis for grounding grids is put forward.The automatic generation of hierarchical simplification model,the software realization of testability evaluation,software realization of uncertain branch groups dividing and generation of their prototypes are detailed.The way to evaluate the possible value ranges of uncertain branches is also described.A grounding grid with sixty branches is used as an example to illustrate the proposed methods,the results of which show the feasibility of the proposed methods.
