摘要
提出了一种新的实现配电网故障定位的不确定推理系统,该系统基于用户投诉的不精确信息,采用贝叶斯不精确推理法和面向对象技术,可以排除少数故障投诉中错误信息的不利影响,最终获得比较可信的故障定位结果;论述了面向故障定位的配电网建模方法和贝叶斯不精确推理方法;详细讨论了投诉信息的可信度和不精确规则等主观参数的设置方法以及故障定位算法。文中给出了典型算例,计算结果表明该系统有效地解决了配电网故障定位中的不确定性问题。为配电网的故障定位提供了一种高效的解决方案。
A new uncertainty reasoning system for locating faults of distribution system is presented based on the uncertain information of trouble calls. Object-oriented technology and Bayes method of reasoning are adopted. The bad effects of mistaken information in a few trouble calls can be eliminated. Consequently, the reliable reasoning result of fault location can be obtained. Modeling a distribution network for locating faults is described. Bayes method of uncertainty reasoning is discussed as well. Fault threshold values of the nodes are defined. Parameters of the reliability of trouble call informations, uncertainty reasoning rules and the fault locating algorithm are the detailed. Typical examples are given in the paper.Calcalation results show that the uncertainty problem in fault location reasoning is well solved.The proposed approach is proved to be feasible.
