Electric energy meter quality consistency evaluation method based on random sampling and medium

Abstract

The invention discloses an electric energy meter quality consistency evaluation method based on random sampling and a medium, relates to the technical field of electric energy metering, and solves theproblems that an existing evaluation method is large in human interference factor and small in sampling sample, and a sampling test needs to be carried out independently. The method comprises the steps of carrying out a full-inspection test, constructing an overall sample space, constructing a sub-sample space, carrying out data sampling on the sub-sample space, carrying out sub-sample space error consistency calculation and carrying out error consistency result identification. The invention can be realized through software, a sampling error consistency test does not need to be independentlycarried out, and the time cost and the labor cost can be effectively reduced; manual intervention is not needed, human factor interference can be effectively eliminated, and fairness and justice of results are ensured.

Description

technical field [0001] The invention relates to the technical field of electric energy metering, in particular to a method and medium for evaluating the quality consistency of electric energy meters based on random sampling. Background technique [0002] With the continuous development of economy and society, electric energy meters have been more and more widely used. A large number of electric energy meters are sent to thousands of households after passing the verification of the compulsory verification organization, and they play the role of trade settlement. [0003] For smart energy meters, before they are officially put into use, the mandatory verification agency will follow JJG596 "Electronic AC Energy Meter", JJG 1099-2014 "Prepaid AC Energy Meter", JJG 569-2014 "Maximum Demand Energy Meter" and JJG691 -2014 "Multi-tariff AC Electric Energy Meter" and other metrology verification regulations to verify its metering performance. When the error value measured by the ve...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is: in the existing evaluation methods, there are many human interference factors, small sampling samples and the need to carry out separate sampling tests, etc.

This method can reduce the hidden dangers of batch quality to a certain extent, but there are still problems such as human interference with the sampled electric energy meter, small number of samples, and the need to conduct separate sampling tests.
