摘要：

With the continuous advancement of smart grids and the digital substations, transformers and electric energy meters in traditional metering systems will gradually be replaced by electronic transformers and meters, the electric energy metering will also enter the digital value. The accuracy of electric energy measurement is directly related to the benefits of power generation, power supply and electricity consumption in the settlement. As an emerging product, the computer-aided electric energy metering system (EES) is still being improved in all aspects. This article first introduces the development background and status quo of the computer-aided electric energy metering system, combining the computer-assisted electric energy metering system composed of electronic transformers, merging units and digital electric energy meters in the smart grid, and putting forward the factors that influence the results of electric energy metering. Aiming at the typical influencing factors, a test method for the verification of measurement errors is proposed, and part of the test is performed on the electric energy meter with the test equipment to verify the analysis results. Based on the analysis of the error factors of computer-aided electric energy measurement, suggestions for reducing errors are proposed, suggestions for improving the function of electric energy meters, and constructive opinions on error verification methods of computer-aided electric energy measurement systems. © 2022 CAD Solutions, LLC, http://www.cad-journal.net.
