Method and system for locating fault of complex power line, device, and storage medium

Abstract

A method and a system for locating a fault of a complex power line are provided. Several monitoring points on the complex power line can be obtained by providing several traveling wave head monitoring sensors on the complex power line. The complex power line is transformed into coordinates in conjunction with an arrival moment and a location corresponding to the monitoring points, thereby establishing a trunk line fault-locating equation related to a line location, the arrival moment, and a traveling wave propagation speed, from which a first fault point can thus be derived simply and quickly. If a fault point is located on a branch line, a branch line fault-locating equation is then established to derive a second fault point. Furthermore, the first fault point and the second fault point serve as a basis for deriving a target fault point of the complex power line.
