High-voltage cable partial discharge mode identification method, computer equipment and storage medium

Abstract

The invention provides a high-voltage cable partial discharge mode recognition method, and the method comprises the following steps: obtaining training data through laboratory data, dividing the training data into a training set and a test set, and collecting onsite to-be-recognized data; respectively inputting the training set into a plurality of classifiers for training, respectively inputting the test set into the trained classifiers for testing, and inputting to-be-identified data acquired on site into the trained classifiers to obtain a preliminary identification result; taking the preliminary identification result as input data, constructing a partial discharge mode identification model by adopting a learning method taking a support vector machine as a classifier, and then inputtingthe input data into the partial discharge mode identification model for testing to obtain a tested partial discharge mode identification model; and inputting to-be-identified data acquired on site into the tested partial discharge mode identification model, and outputting to obtain a high-voltage cable partial discharge integrated mode identification result.

Description

technical field [0001] The present invention relates to the technical field of partial discharge identification, more specifically, to a high-voltage cable partial discharge pattern identification method based on the combination of multiple classifiers, computer equipment and storage media. Background technique [0002] Since high-voltage cables have been running at high voltage and high current for a long time, under the action of external force damage, equipment defects, water tree intrusion and other factors, different types of defects will cause partial discharge of high-voltage cables, and partial discharge of high-voltage cables will cause internal electric shocks in the cable insulation. The generation and expansion of trees will accelerate the deterioration of insulation and eventually lead to breakdown, which will bring huge hidden dangers to the safe operation of the power system. Therefore, in order to discover potential safety hazards caused by partial discharge ...
