Intelligent electricity stealing checking system and method based on non-invasive load monitoring

Abstract

The invention discloses an intelligent electricity stealing checking method based on non-invasive load monitoring, which mainly comprises the following steps of: (1) judging whether an electricity user is a suspected electricity stealing user; (2) dividing the electric equipment of the user into electric equipment, the operation state of which can reflect a whole-day electricity utilization behavior of the user and is suitable for analyzing the behavior of intermittent meter throwing and electric equipment, the monitoring result of the operation state of which is not influenced by the behaviorof less metering and electricity stealing; secondly, calculating an evaluation index of the electricity stealing behavior; (3) judging the electricity stealing behavior of the user; (4) estimating the electricity stealing quantity of the user by utilizing the relation between the accumulated electricity consumption of the same type of electric equipment and the total electricity quantity of the user under the normal condition and the judgment result of the electricity stealing behavior of the user. According to the invention, the non-invasive load monitoring technology is utilized to acquirethe power utilization detail data, so that the defects that the prior method is difficult to utilize at a household and evidence is difficult to obtain are overcome, and the accuracy and reliability of the inspection of the two electricity stealing behaviors are improved.

Description

technical field [0001] The invention belongs to the field of electricity stealing inspection of electric power users, and in particular relates to an intelligent electricity stealing inspection system and method based on non-intrusive load monitoring. Background technique [0002] my country's power system is developing rapidly, with almost exponential growth in power generation, installed power capacity, and related infrastructure. However, due to the mismatch between the speed of development and the relevant regulatory governance, and the imperfection of power consumption governance technology, no practical and effective countermeasures have been found for abnormal power consumption supervision. Among them, the amount of energy and economic losses caused by electricity theft is huge every year, and the upward trend is obvious. Therefore, it is imperative to find a reasonable method to rectify the electricity theft behavior of power users. [0003] Several typical cases hi...

AI Technical Summary

Problems solved by technology

[0004] High-tech means of stealing electricity are becoming more and more hidden, which leads to a significant increase in the difficulty of law enforcement when conducting electricity theft inspections, whether it is in the process of determining user stealing behavior, or in the process of estimating and recovering electricity charges for stealing electricity

In addition, sometimes even though it is found that the electricity metering is wrong, it cannot be classified as electricity theft because of the failure to conduct a reasonable analysis of electricity consumption behavior, resulting in a waste of electricity.
