Analysis of Single Phase Grounding Fault Location Method in Distribution Network Based on Quantum Genetic Algorithm

阐述基于量子遗传算法的配电网单相接地故障定位方法。以检测出配电网线路暂态零序电流信息作为单相接地故障特征,以电流实际检测值和期望值之间差值最小为目标,构造对应的目标适应度函数作为单相接地故障选线判据,引入量子遗传算法求解函数,完成配电网单相接地故障区段定位。

This paper describes the method of single-phase grounding fault location in distribution networks based on quantum genetic algorithm.It detects the transient zero sequence current information of the distribution network line as the characteristic of single-phase grounding fault,with the goal of minimizing the difference between the actual detection value and the expected value of the current.It constructs a corresponding target fitness function as the criterion for single-phase grounding fault line selection,introduces quantum genetic algorithm to solve the function,and completes the positioning of single-phase grounding fault sections in the distribution network.
