Design and Research of Automatic Error Correction Algorithm for Electric Energy Metering Device

Aiming at the problems of long error correction time and poor correction effect of electric energy metering device, an automatic correction algorithm design of electric energy metering error is proposed. First, the stationary characteristics of the electric energy metering device when errors occur are extracted, and the regular interval of error correction is found. Second, in the regular interval, the average power of the quantization error of the metering device is determined, and the location of the error is found. Finally, the stability is corrected according to the error. According to the interval and error position, an automatic error correction model is constructed, which shortens the error correction time, enhances the automatic error correction of the power calculation device, and realizes the accurate correction of the power calculation error. The comparative experimental results show that the error correction time of the algorithm is short, and it has the ability of real-time error correction, which can be applied in real life.
