Fault location method and device for distribution network, equipment, storage medium, and program product

Abstract

A fault location method and device for a distribution network, equipment, a storage medium, and a program product. Method includes: acquiring node at least one network node' state data in a power network and constructing a power network state incidence matrix based on each network node's state data; and determining a power grid characteristic constraint of the power network state incidence matrix and determining a fault section corresponding to the power network state incidence matrix according to power grid characteristic constraint and a preset fault location model. The fault section located by analyzing the power network state incidence matrix. Through a precise boundary, the preset fault location model can accurately identify a fault characteristic, such that the fault location precision is improved. The power network state incidence matrix and power grid characteristic constraint can be adjusted based on a dynamic change of a topological structure of a power network.
