Medium-voltage anti-electricity-stealing analysis method based on coding correlation

Abstract

The invention relates to the technical field of anti-electricity-stealing analysis, and discloses a medium-voltage anti-electricity-stealing analysis method based on coding correlation, which comprises the following steps that: a master station acquires daily frozen electric quantity data of a line general meter and each line gateway meter; preprocessing the daily frozen electric quantity data; subtracting the sum of the table day frozen electric quantity data of each line gateway from the total table day frozen electric quantity data to obtain a line day line loss value; performing first-order difference operation on the daily freezing electric quantity of each line gateway and the daily line loss value of the line; coding according to a first-order difference operation result; obtaining a correlation coefficient between each line gateway table and a line daily line loss value according to a coding result; the line gateway meters with the correlation coefficients exceeding a certain threshold value are suspected electricity stealing meters. According to the method, electricity stealing prevention equipment does not need to be additionally arranged on the line, electricity stealing judgment can be achieved only by freezing the daily electricity data of the line general meter and the line gateway meters, on the basis that judgment accuracy is guaranteed, the workload is small, implementation is easy, and time, economic cost and labor cost are saved.

Description

technical field [0001] The invention relates to the technical field of anti-stealing electricity analysis, in particular to a medium-voltage anti-stealing electricity analysis method based on coding correlation, which is mainly used for analyzing and judging electricity theft of medium-voltage users in a power distribution automation system. Background technique [0002] With the continuous increase of electricity consumption in the society as a whole and the rapid development of science and technology, the methods of stealing electricity have become more and more hidden, and the problem of electricity theft has become a problem that plagues power companies. However, medium-voltage users consume a lot of electricity. Driven by economic interests, they are more likely to have the idea of ​​taking risks and stealing electricity. Stealing electricity is not only easy to cause hazards such as fire and line failure, but also causes huge economic losses to the country and power co...

However, medium-voltage users consume a lot of electricity. Driven by economic interests, they are more likely to have the idea of ​​taking risks and stealing electricity.

Stealing electricity is not only easy to cause hazards such as fire and line failure, but also causes huge economic losses to the country and power companies

At present, the common medium-voltage anti-stealing method is mainly to install additional anti-stealing equipment on each medium-voltage line, and to find the electric-stealing meter by comparing the current recorded by the equipment and the electric energy meter at the gateway of the line. The cost of installing anti-stealing equipment on each line is too high
