A fault remote judgment method and system for a smart electric energy meter

Abstract

The present invention provides a method and system for fault remote determination of an intelligent ammeter. The method comprises: obtaining voltage and current parameter values collected by an intelligent ammeter through a remote communication interface; comparing obtained voltage and current parameter values with a preset threshold; is the voltage and current parameter values and a normal value exceed the preset threshold, determining that the intelligent ammeter is located in a fault state; obtaining the position of the intelligent ammeter located in the fault state and collecting a plurality of influence factor conditions corresponding to the position; comparing with a preset history database according to the influence factor conditions, and obtaining normal corresponding parameter values of the intelligent ammeter; and determining the fault type of the intelligent ammeter through a preset fault determination rule on the basis of the normal parameter values. Through adoption of a comparison method, the method and system for fault remote determination of intelligent ammeter are able to more reliably determine the faults of an intelligent ammeter and avoid the one-sided view of data because of providing elaborate determination basis and determination results.

Description

technical field [0001] The invention relates to the technical field of electric energy meters, in particular to a remote fault judgment method and system for an intelligent electric energy meter. Background technique [0002] At present, with the construction of smart grid, the promotion of smart meters and the continuous development of technology, real-time collection and remote analysis of energy meter data can be realized. The invention patent document of CN1368777A mentions the electric energy meter remote data acquisition scheme. [0003] However, in the existing method for judging the failure of the electric energy meter at the site of the electric power user, the traditional method of manually arriving at the scene to detect and verify the electric energy meter is still used for judgment. This method needs to consume a lot of human resources of the power company, and it is impossible to detect the failure of the electric energy meter in time, and it is difficult to c...
