A method and device for identifying electricity theft

Abstract

An embodiment of the invention provides an electricity stealing identification method and an apparatus thereof. The method comprises the following steps of acquiring electricity utilization data of a user to be identified; calculating a preset abnormal electricity utilization index according to the electricity utilization data of the user to be identified; and if the user to be identified is an abnormal user, according to the abnormal electricity utilization index of the user to be identified, generating an electricity utilization characteristic vector of the user to be identified; calculating a similarity value of the electricity utilization characteristic vector of the user to be identified and an electricity stealing fingerprint vector of each preset electricity stealing method; if any similarity value acquired through calculation exceeds a preset threshold, indicating that the user to be identified is a suspected electricity stealing user. In the embodiment, through calculating the similarity value of the electricity utilization characteristic vector of the user to be identified and the electricity stealing fingerprint vector, whether the user to be identified belongs to the suspected electricity stealing user is automatically identified, subjective assumption made by an expert on electricity stealing identification is avoided and accuracy of electricity stealing identification is increased.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a method and device for identifying electricity theft. Background technique [0002] With the rapid development of my country's economy, the user's demand for electricity is growing rapidly. However, the stealing of electricity, especially the stealing of special transformers is becoming more and more serious, the methods of stealing electricity are becoming more and more abundant and concealed, and the loss of electricity stealing is increasing year by year. [0003] In the prior art, the identification of the stealing behavior of special transformers is usually analyzed based on expert experience. This analysis method is highly subjective and the identification accuracy is low. Contents of the invention [0004] In view of this, the embodiment of the present invention provides a method and device for electricity theft identification. Through the method of this embodiment, not o...
