Low-voltage user electricity stealing identification method based on side-end fusion

Abstract

The invention discloses a low-voltage user electricity stealing identification method based on side-end fusion. The method comprises the following steps: acquiring multivariate power utilization data of a user through cooperation of side end equipment, and processing to obtain power stealing suspicion quantitative parameters for a single-phase user based on cover opening event records, zero line current, live line current and a voltage load curve; for the three-phase user, based on the cover opening event record, the voltage load curve and the active power load curve, processing to obtain an electricity larceny suspicion quantitative parameter; and establishing an electricity larceny suspicion weight model of the single-phase and three-phase meters, determining weight parameters in the electricity larceny suspicion weight model through an analytic hierarchy process, calculating electricity larceny suspicion parameters, and judging to obtain an electricity larceny identification result. According to the invention, the multi-element power consumption data characteristics of the user are fully utilized, the electricity stealing behavior of the user can be effectively identified, additional monitoring equipment is not needed, and high investment, operation and maintenance cost is avoided; and meanwhile, the influence of factors such as high data communication pressure and poor clock synchronism on the recognition accuracy can be effectively relieved by utilizing the cooperation of the edge end equipment on data acquisition.

Description

technical field [0001] The invention relates to a power consumption detection method of an electric power internet of things information system, in particular to a low-voltage user electricity stealing identification method based on edge-end data fusion. Background technique [0002] As the relationship between social and economic development and electricity becomes closer and closer, some criminals are driven by economic interests to use various means to steal electricity, and the phenomenon of electricity theft is repeatedly prohibited. The problem that has plagued power supply companies for a long time not only seriously damages the benefits of power supply companies and disrupts the normal order of power consumption, but also causes damage to power facilities and poses a major power safety problem. It has become a topic that cannot be ignored. Power supply companies have been increasing their efforts to combat electricity theft, and are also constantly improving the tech...
