Embodiment Construction

[0029] The specific implementation of a method for judging and locating a single-phase user electricity stealing according to the present invention will be described in detail below.

[0030] The method for judging and locating electricity stealing by a single-phase user of the present invention is mainly for judging whether a single-phase electricity user has electricity stealing behavior, monitoring whether people's electricity usage behavior is legal, and maintaining the order of electricity usage.

[0031] The method for judging and locating a single-phase user stealing electricity of the present invention is mainly the collection and analysis of signals, specifically comprising the following steps: Step (1): collecting the active power signal of the dedicated variable collection terminal and the active power signal of the electric energy concentrator; step (2): Calculate the sum of the active power signals of the electric energy concentrator; step (3): calculate the differ...

Abstract

The invention provides a single-phase user electricity stealing determination and positioning method. It is determined whether each electric energy meter works normally or not by detecting a CT and mainly through signal collection and layer-by-layer analysis, if each electric energy meter works abnormally, Users with abnormal electricity utilization is further determined, an alarm is controlled for alarm, abnormal information is displayed, and concrete user information with the abnormal electricity utilization is sent to electricity utilization inspectors. The single-phase user electricity stealing determination and positioning method provided by the invention can preliminarily discover and position abnormal electricity users and can avoid electricity larceny behaviors.

Description

technical field [0001] The invention belongs to the technical field of electricity consumption detection, and in particular relates to a method for judging and locating single-phase user stealing electricity. Background technique [0002] With the development of various large and medium-sized industrial enterprises in our country, the electricity consumption has also increased rapidly. Driven by profit, the electricity stealing behavior of large electricity consumers is becoming more and more serious, and the technology and methods of stealing electricity are becoming more and more diversified. Stealing electricity not only threatens the economic interests of electric power enterprises, but also greatly affects the stable development of my country's electric power industry, and brings great security risks to people's production and life. Faced with the diversification of electricity stealing methods and the increasing technology of electricity stealing, the electric power in...
