Embodiment Construction

[0028] The specific implementation of a method for judging and locating a three-phase user electricity stealing according to the present invention will be described in detail below.

[0029] The method for judging and locating electricity stealing by a three-phase user of the present invention is mainly for judging whether a three-phase electricity user has electricity stealing behavior, monitoring whether people's electricity usage behavior is legal, and maintaining the order of electricity usage.

[0030] The three-phase user electric stealing judgment location method of the present invention mainly is the collection and analysis of signal, specifically comprises the following steps: step (1): collect special variable acquisition terminal active power signal, electric energy concentrator active power signal; Step (2): Calculate the sum of the active power signals of the electric energy concentrator; step (3): calculate the difference between the sum of the active power signal...

Abstract

The invention provides a three-phase user electricity stealing judging and positioning method. Through signal acquisition, layer-by-layer analysis is performed according to information acquired by each stage of signal acquisition equipment, whether each electric energy meter works normally or not is judged through detection CT, if each electric energy meter works abnormally, a user with abnormal electricity utilization is further judged, then abnormal information is sent to electricity utilization inspectors, specific abnormal conditions are further judged, and final judgment is made. The invention provides the three-phase user electricity stealing judging and positioning method, which can preliminarily discover and position abnormal electricity users and prevent electricity stealing behaviors.

Description

technical field [0001] The invention belongs to the technical field of electricity consumption detection, and in particular relates to a three-phase user stealing electricity judging and positioning method. 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 indu...
