基于稍峰组的馈线故障寻址新方法

A New Method of Feeder Fault Addressing Based on Treetop Peaks

针对馈线故障寻址中经常遇到的多区段故障、故障指示器拒动或误动等问题,将具有局部最大故障解释可信度的区段定义为峰,分析了区段组故障解释可信度与相应的稍峰组故障解释可信度之间的关系,将寻找最大故障解释可信度区段组问题变成了寻找最大故障解释可信度稍峰组问题。同时,提出了一种尾部添峰法,使所有稍峰组及不一致故障指示器数都能快速地演绎。

Considering the multi-section fault, the mal-operation, and the refusal-operation of fault indicators often encountered at the time of fault addressing,we define a section which has the local maximal fault explanatory credibility as a peak and analyze the relationship between the fault explanatory credibility of sections and that of the corresponding treetop peaks. Therefore,the task is transformed from finding the section which has the maximal fault explanatory credibility to finding the corresponding the treetop peak with the maximal fault explanatory credibility. Meanwhile we propose an attaching peak algorithm so that all treetop peaks and inconsistent fault indicators can be easily deducted.
