Embodiment 1

[0040] This embodiment is a staged and stratified sampling method for operating smart electric energy meters. The method is specifically, obtaining the total amount of intelligent electric energy meters to be sampled, and sampling the intelligent electric energy meters to be sampled in stages according to time sequence, and sampling in stages Including the first-stage sampling and the second-stage sampling in sequence, both the first-stage sampling and the second-stage sampling are stratified sampling for smart energy meters, and the second-stage sampling is based on the results of the first-stage sampling.

[0041] Specifically, stratified sampling is to perform stratified sampling on the operating smart energy meters based on the manufacturer, model, specification and / or purchase year. In this embodiment, stratified sampling is performed based on the manufacturer. In the first stage of sampling and the second stage of sampling, the sample size is obtained according to the pre...

Abstract

The invention relates to a staged and stratified sampling method for operating an intelligent electric energy meter. The method is specifically as follows, the total quantity of the to-be-sampled intelligent electric energy meters are obtained; according to the time sequence, the intelligent electric energy meters to be sampled are sampled in stages, the stage sampling comprises first-stage sampling and second-stage sampling which are carried out in sequence, the first-stage sampling and the second-stage sampling are both used for carrying out stratified sampling on the intelligent electric energy meters, and the second-stage sampling is carried out according to the result of the first-stage sampling. Compared with the prior art, the method has the advantages that the real state of the running intelligent electric energy meter can be accurately reflected, the sample amount is small, time and economic cost are saved, and the reliability of a sampling result is high.

Description

technical field [0001] The invention relates to the field of smart electric energy meters, in particular to a staged and stratified sampling method for operating the intelligent electric energy meter. Background technique [0002] With the comprehensive construction of the smart grid and the transformation and upgrading of rural power grids, the smart energy meter market is developing rapidly, and will basically achieve full coverage of smart energy meters. The application of metering equipment presents the characteristics of large quantity, various types, intelligence, and complex operating environment. At present, the State Grid has nearly 220 million smart energy meters connected to the grid, and the Southern Power Grid has nearly 50 million smart energy meters connected to the grid. In the future, the combined smart energy meters and power consumption management system market of the two major power grids will exceed 16 billion yuan per year. The stability and reliabilit...
