Popis: The harmonics generated by a large number of power electronic equipment in the power grid will seriously affect the measurement accuracy of electric energy measuring instruments. Therefore, in order to determine the anti-harmonic interference performance of electric energy meters, harmonic influence tests are required in the national standards of electric energy meters and the type evaluation outline. As the main standard device used in the harmonic impact test of the electric energy meter, the reference meter has passed the measurement verification, but its verification items do not include the detection of the harmonic measurement performance. In order to ensure the validity of the harmonic impact test of the electric energy meter, it is necessary to test the harmonic measurement performance of the reference meter. This paper designs a set of measurement and detection schemes that uses power comparison method to trace the source of harmonics of reference meters. It has important reference value for improving the accuracy of harmonic measurement and the reliability of electric energy meter type test.
