Abstract

The embodiment of the invention relates to a fault identification and positioning method, device and apparatus for substation power equipment. The method comprises five steps of data acquisition, datapreprocessing, model image construction, image feature extraction and image classification to construct a fault identification model. The method comprises the following steps of inputting a to-be-detected image of power equipment of a transformer substation into a fault identification model, identifying and analyzing whether the power equipment in the to-be-detected image has a fault or not by the fault identification model, and if so, identifying and analyzing the fault position of the power equipment of the transformer substation. The fault position of the power equipment of the substationcan be identified, the identification efficiency is high, a large amount of manpower and material resources do not need to be input, and the accuracy and efficiency of identifying the fault of the power equipment are greatly improved by eliminating the interference of cluttered images and irrelevant factors on fault identification. The technical problems that a large amount of manpower and material resources need to be invested and the working efficiency is low in a traditional transformer substation inspection and fault detection method are solved.

Description

technical field [0001] The invention relates to the technical field of electric equipment fault identification, in particular to a fault identification and location method, device and equipment for substation electric equipment. Background technique [0002] With the rapid development of the electric power industry, a large number of substations are produced. It is a complex project for a substation to grow from scratch, from stability to sustainable use. The establishment of a substation puts forward high requirements for infrastructure construction. The power generation equipment required by the substation is not only large in number, but also sophisticated and complex, which means that the workload of equipment line laying is huge. [0003] In the traditional construction process of a substation, a large number of drawings, data, and reports will be generated, which is not easy to manage, and involves multiple disciplines and departments. Once some difficulties are encoun...
