Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0032] Such as figure 1 As shown, a method for analyzing abnormal power consumption of large power users includes the following steps:

[0033] Step 1. Based on the power metering data, use the regular discontinuous analysis method and the classification continuous difference analysis method to analyze the user's abnormal electricity consumption, and build an abnormal list.

[0034] Such as figure 2 As shown, the process of the regular discontinuous analysis method is: analyze the voltage or current curve based on the power metering data; If the same fluctuation occurs continuously, that is, abnormal and normal appear alternately, it is determined that the user's electricity consumption is a...

Abstract

The invention discloses a power consumption abnormality analysis method for a large power consumer, and the method comprises the steps: carrying out the user power consumption abnormality analysis based on power measurement data, and constructing an abnormality list; and performing metering device anomaly analysis, transformer area line loss anomaly analysis, meter dismounting anomaly analysis andthree-phase imbalance analysis on elements in the anomaly list to obtain a user anomaly result list. The invention further discloses a corresponding system. According to the invention, the exceptionlist is constructed based on the metering data, metering device exception analysis, transformer area line loss exception analysis, meter dismounting exception analysis and three-phase imbalance analysis are carried out on all elements in the exception list, exception results of all users in the exception list are obtained, and compared with a traditional analysis method, the method does not dependon personnel experience, and analysis is more thorough.

Description

technical field [0001] The invention relates to a method and system for analyzing abnormality of electricity consumption by a large electric power user, belonging to the field of abnormality analysis. Background technique [0002] Electric power takes key parameters such as voltage and current, and key technical indicators such as line loss as the entry point to carry out metering technical supervision work, and implement online monitoring, precise positioning, and tracking supervision of the master station for various user metering device failures and breach of contract and electricity theft. However, the current identification process of abnormal electricity consumption of users relies too much on the experience of staff, and the analysis is not thorough. It is urgent to design a unified analysis method for abnormal electricity consumption of large users. Contents of the invention [0003] The present invention provides a method and system for analyzing abnormal power co...
