Automatic Error Correction Method for Induction Energy Measurement Based on Harmonic Analysis
The current error correction of induction energy metering can only be carried out in laborato-ries or specific testing environments,requiring manual intervention and operation,resulting in significant fluc-tuations in voltage harmonic amplitude.Therefore,a method for automatic error correction of induction energy metering based on harmonic analysis is studied.Determine the amplitude of harmonics through harmonic anal-ysis,and gain a deeper understanding of the impact of harmonics on electricity meter measurement.Establish a measurement error correction model for induction energy meters,and compare and analyze actual measure-ment results with theoretical values.Determine the corresponding coefficients to correct measurement errors and improve the accuracy and reliability of electricity metering.The experimental results show that compared with deep learning based correction methods and frequency-domain analysis based correction methods,the au-tomatic correction method of induction power metering error based on harmonic analysis for measurement error correction stabilizes the voltage harmonic amplitude within 0.05％and has better stability.
