An electric energy meter even harmonic compensation method, device, equipment and storage medium

Abstract

The present application relates to the technical field of electric energy meter, and discloses an electric energy meter even harmonic compensation method, device, equipment and storage medium, the method comprises the following steps: obtaining current sampling data of the electric energy meter; obtaining the current according to the current sampling data, and performing harmonic analysis on the current sampling data to obtain the current even harmonic content rate; when the current reaches the preset current threshold and the current even harmonic content rate is in the preset interval, matching the compensation parameter corresponding to the current based on the preset compensation parameter table; calculating the compensation value based on the compensation parameter, the current and the factory calibration parameter; and compensating the electric energy meter based on the compensation value. The present application realizes the adaptive and accurate suppression of even harmonics in the full current range by matching the compensation parameter according to the current interval classification, and effectively improves the measurement accuracy of the electric energy meter under complex harmonic conditions.
