摘要
为解决配电网终端设备故障等引起的故障信息漏报或误报造成的故障定位系统定位区域不准确问题,论文在现有的基于矩阵理论的故障定位算法基础上,研究一种采用贝叶斯分析方法的配电网容错故障定位方法。首先采用矩阵故障定位算法计算出可能存在故障的疑似区域,然后再采用基于贝叶斯的分析方法计算出所有这些区域的可能发生故障的概率,最后可判断出实际的故障区域。通过实例运算,验证了算法的准确性和可行性。
In order to solve the problem of inaccurate positioning area for the fault location system caused by failure or misstatement information of the FTU （Feeder Terminal Unit）, TTU （Transformer Terminal Unit） or the DTU（Distribution Terminal Unit）, the paper studies a fault-tolerant fait location algorithm based on theory of matrix and Bayesian analysis for power distribution ibution network. Firstly, the suspected fault regions are calculated based on the matrix fault location algorithm, and then the Bayesian-based analysis method is used to calculate the probability of all the suspected fault regions. Finally, the actual fault area can be judged according to robability of of all the sus-pected fault regions. The accuracy and feasibility of such method are verified by example calculations.
