Detection method of user's electricity consumption behavior of user based on clustering analysis

Abstract

The invention provides a detection method of a user's electricity consumption behavior based on clustering analysis. According to the detection method, a user data warehouse is created so as to collect user's electricity consumption information, the created user data warehouse is processed to form principal component data so as to process large sample data, and the mining efficiency is improved; clustering calculation is conducted on the principal component data to obtain different user's electricity consumption modes, wherein outlier objects in the user's electricity consumption modes probably are electricity stealing users, and then electricity stealing suspected users are obtained by calculating for the outlier objects by means of the hierarchical clustering method. In the provided detection method of the user's electricity consumption behavior based on the clustering analysis, the hierarchical clustering method only needs to sequence the distance between the objects and conduct clustering according to a distance sequence, and the objects do not need to be inspected or estimated; meanwhile, the detection of the outliers and the clustering calculation are highly complementary, and good scalability is achieved.

Description

technical field [0001] The invention relates to the technical field of electricity consumption behavior detection, in particular to a user electricity consumption behavior detection method based on cluster analysis. Background technique [0002] Electricity theft refers to the act of not measuring or under-metering electricity consumption by illegal means for the purpose of not paying or underpaying electricity charges. Stealing electricity not only seriously damages the interests of power supply enterprises, but also disturbs the normal order of power supply and utilization, seriously affects the development of electric power industry, and poses a serious threat to the safety of electricity utilization. Once the stealing of electricity takes place on a certain scale, it will greatly increase the burden on the power supply line, at least it will affect the voltage stability of the entire community, and at the worst it will cause a power outage in the entire area and affect t...

Problems solved by technology

Electricity theft is usually discovered when the electricity meter is checked or the bill is paid. However, the electricity theft has already occurred at this time and the power supply system has been damaged. Electricity behavior cannot be known in advance, and electricity theft cannot be stopped in advance

[0004] At present, the methods of preventing electricity theft in our country mainly include the use of special metering boxes or meter boxes, and the installation of anti-theft equipment.

If the anti-stealing device is replaced only for individual users, only the users who have installed and replaced the anti-stealing device can be controlled, and the electricity consumption behavior of all users in the entire area cannot be detected, so there may still be missed detection electricity stealing users
