Power distribution network fault positioning method and device based on adaptive weighted average algorithm

The invention is applicable to the technical field of power distribution network fault positioning, and provides a power distribution network fault positioning method based on an adaptive weighted average algorithm, which comprises the following steps: firstly, acquiring line operation state information of a to-be-detected power distribution network; determining the fitness of each section according to the line operation state information; then, a population is initialized based on a self-adaptive weighted average algorithm; selecting individuals meeting a preset rule in the current population according to the fitness; determining a population updating rule according to the selected individuals and performing population updating; and finally, when the population is updated to the maximum number of iterations, determining the position of the fault point of the power distribution network according to the optimal solution of the population. According to the embodiment of the invention, by calculating the fitness
