Abstract

The invention discloses an electricity stealing detection method and device of using an integrated entropy method and a density clustering method, wherein the detection method comprises the followingsteps of: acquiring user intelligent meter data and total energy consumption data in a period of time to be detected in a target area to obtain a user power consumption curve set and non-technical loss data; processing the user power consumption curve set and non-technical loss data according to a maximum information coefficient calculation method, and obtaining a power consumption correlation measurement index; obtaining a shape anomaly index of each curve; according to the measurement index and the shape anomaly index, dividing the power consumption curve of each user into an abnormal curveand a normal curve through the k-Mean value clustering, and obtaining an abnormal index of power quantity and an abnormal index of shape; and then obtaining the power quantity anomaly rank and shape anomaly rank of the users to obtain the comprehensive anomaly rank. The method can improve the accuracy of detection in various power stealing modes, realize the unsupervised detection of the power stealing behavior under large data, and enlarge the application scope.

Description

technical field [0001] The invention relates to the technical field of anti-stealing electricity analysis, in particular to a method and device for detecting electricity theft using a comprehensive entropy method and a density clustering method. Background technique [0002] In recent years, with the popularization of smart meters in the power grid, the attack methods of electricity thieves on meters are no longer limited to traditional physical cutting or destruction, and a new mode of tampering with smart meters by using digital storage technology and network communication technology has emerged. . Under this new type of attack, smart meter data obtained by grid companies may be carefully forged by electricity thieves. On the other hand, smart meters can record user electricity consumption data more than dozens of times a day, providing massive data for power grid companies. In the traditional sense, the detection of electricity theft mainly depends on the power grid com...
