Abstract

The invention discloses an error remote estimation method and system for an intelligent electric meter, a terminal and a storage medium. The method comprises the following steps: acquiring transformer area and user file data and electric quantity data of the intelligent electric meter; preprocessing the electric quantity data of the intelligent electric meter, and taking the preprocessed electric quantity data as electric quantity sample data; according to the electric quantity sample data, the transformer area and user archive data and a transformer area electric energy loss calculation method, constructing a standardized perception matrix and a measurement vector group; and calculating the metering error of each intelligent electric meter in the transformer area by adopting a self-adaptive parameter regularization orthogonal matching pursuit algorithm for the standardized sensing matrix and the measurement vector group. The calculation efficiency in the electric power metering process can be improved, and a guarantee is provided for monitoring the error of the electric energy meter in a running state in real time.

Description

technical field [0001] The invention relates to the technical field of smart meter error calculation, in particular to a method, system, terminal and storage medium for remote estimation of smart meter errors. Background technique [0002] With the reform of the electric power system, the separation of power plants and enterprises, and the gradual enterprise operation of power grid companies, the management of electric energy measurement is becoming more and more important, which directly affects the economic benefits of power supply enterprises. In this context, it is important to determine the measurement error of a smart meter. According to the current metering status or operating status of each electric energy meter, it is inferred that there may be a faulty electric energy meter, so that the staff can replace it in time, which is the basis for ensuring the accuracy of grid measurement. [0003] At present, the main way to test whether the meter is accurate is to carry ...
