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.
