Power consumption analysis method, system and equipment for special transformer and low-voltage user, and storage medium

Abstract

The invention discloses a power consumption analysis method, system and equipment for a special transformer and a low-voltage user and a storage medium, and relates to the technical field of power utilization detection. The method comprises the following steps: acquiring a plurality of historical power consumption data; training and stacking the auto-encoders according to historical power consumption data, and outputting power consumption characteristics after dimension reduction; introducing a supervised classification layer, and performing fine tuning on parameters of the auto-encoder; adopting a category imbalance processing method based on random undersampling and resampling to obtain a random forest classifier; and adopting a random forest classifier to classify each user on the test set, and outputting the electricity larceny confidence of each user on the test set by integrating the classification results of each classifier. According to the invention, a more reasonable and effective troubleshooting strategy can be formulated in combination with an electricity larceny troubleshooting target, so that the problems of time and labor waste and low accuracy of an existing electricity larceny troubleshooting method are solved.

Description

technical field [0001] The present invention relates to the technical field of electricity consumption detection, in particular to a method, system, equipment and storage medium for analyzing electricity consumption of special transformers and low-voltage users. Background technique [0002] Electricity theft refers to the process in which electricity customers use illegal concealed means or other illegal behaviors to realize the measurement of their electricity consumption is less than the actual amount used. Electricity theft is very harmful. If electricity theft users modify the electric energy meter and reconnect the transmission line without permission, it will easily lead to electrical equipment failure, short circuit of the line, and even casualties. Stealing electricity is not only considerable in number, but also the people who steal electricity are specialized and diversified. Because the main body of stealing electricity is varied, it is necessary to analyze the p...
