ATT7022E Based Harmonic Analysis Method Research on Power Quality Monitoring

Xie Zhi-yua

Abstract

According to the characteristics of ATT7022 E metering chip,the harmonic analysis method of power quality monitoring will be analyzed based on ATT7022 E in this paper. FFT as an useful harmonic analysis algorithm in ATT7022 E practical application will be focused on. Two harmonic analysis methods of synchronous sampling data and ADC sampling data have been tested,the results of which show that under the condition of the harmonic signal simulation,this harmonic analysis method has certain reference value in engineering application.
