配电网线路故障的基于模型诊断方法

现有配电网故障诊断系统大多是基于经验的专家系统,但专家系统难以诊断经验之外的故障,而且系统的移植和维护也非常困难。文中将模型诊断(MBD)方法应用于配电网故障诊断。介绍MBD理论的基本概念,给出了一个应用MBD理论的配电网线路故障诊断方案。以一个实际配电网为例,对故障诊断系统进行了建模和实验验证,结果表明该应用方案可行、有效。

Distribution Network Line Fault Diagnosis with Model-based Method

Most of the existing diagnosis systems used in distribution network are expert systems based on experiences,which is not able to diagnose the faults beyond experience and is very difficult for system transplanting and maintaining.In order to overcome the defect of the traditional expert system,the method of model-based diagnosis(MBD) is applied to the distribution network.Through the introduction of a few basic concepts,a scheme using MBD in the fault diagnosis of distribution system line is proposed.Finally,an example of actual distribution network is adopted to verify the feasibility and validity of the method through modeling,programming and testing.
