Abstract

The invention relates to a method and an apparatus for positioning a fault of a power line, a computer device and a storage medium. The method includes the steps of: obtaining line fault data of a to-be-positioned line; obtaining a line fault positioning model that is obtained by preliminary training; analyzing the line fault positioning model to obtain main component matrixes and first characteristic information of multiple fault set groups; performing dimensionality reduction calculation on the line fault data and multiple main component matrixes to obtain multiple pieces of second characteristic information; comparing the second characteristic information with the first characteristic information, and calculating to obtain an Euclidean distance between each piece of second characteristic information and each piece of first characteristic information; and positioning the fault of the to-be-positioned line with the fault set group corresponding to the second characteristic informationthat is corresponding to a minimum Euclidean distance. Therefore, a fault state of the line is positioned efficiently and accurately.

Description

technical field [0001] The present application relates to the technical field of power line fault location, in particular to a power line fault location method, device, computer equipment and storage medium. Background technique [0002] When a fault occurs on a line, it will cause a change in the cross-section power flow, but the power flow information data is huge, and it is very difficult to directly judge the fault information through the power flow data, and it is impossible to guarantee all the data during the whole process of collection, transmission, and exchange of measurement data. They are all accurate, and it is difficult to take all factors into consideration when locating a fault. [0003] Currently commonly used fault location methods, such as alarm performance analysis method, replacement method, configuration data analysis method, based on fault indicator and intelligent analysis master station location, etc. The above methods need to build an expert system...
