Metering device wire misconnection analysis method and system based on internal data of electric energy meter

Abstract

The invention provides a metering device wire misconnection analysis method and system based on internal data of an electric energy meter, and the method comprises the steps: obtaining original data collected by the electric energy meter, and classifying the original data according to an access phase line mode of the electric energy meter; and judging a voltage access mode of the classified data according to a voltage phase sequence, respectively listing a correct expression of a power factor angle and an expression under the current real wiring according to the relationship between the voltage and the current of each element in space, and realizing wire misconnection analysis through the distribution of vectors in the space. Based on the method, the invention further provides the meteringdevice wire misconnection line analysis system based on the internal data of the electric energy meter. According to the invention, strong voltage is not required to be contacted in the operation process, and work contents such as wiring condition analysis, vector diagram drawing, power expression calculation, correction coefficient calculation, electric quantity compensation and electric chargecompensation calculation of an electric energy metering device are completed through database and software analysis by acquiring internal data of the electric energy meter; therefore, electric shock danger is avoided and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of electric energy meter data analysis, in particular to a method and system for analyzing wrong wiring of a metering device based on internal data of electric energy meters. Background technique [0002] Due to the strong professionalism of electric energy metering and electricity inspection, customers cannot be cut off during the inspection process. Live inspection is required to collect various data such as voltage and current into the on-site electricity inspection instrument, and then complete phase diagram drawing error judgment and other work , the operation process is electrified, the wiring is complicated and cumbersome, it is necessary to manually judge the miswiring situation, calculate the correction coefficient, replenish the power, etc., there are safety risks, the work efficiency is slow, the manual calculation results are not pre-approved by the customer, and it is very easy to cause accidents...
