摘要
根据ATT7022E计量芯片的特点,文章给出了基于ATT7022E电能质量监测的谐波分析方法,重点研究了FFT作为谐波分析算法在ATT7022E的实际应用,对采用同步采样数据和ADC采样数据的两种谐波分析方法进行了实验。实验表明在设定谐波信号的情况下仿真,该方法研究对谐波分析的工程实际应用具有一定的参考价值。
According to the characteristics of ATT7022E metering chip, the harmonic analysis method of power quality monitoring will be analyzed based on ATT7022E in this paper.FFT as an useful harmonic analysis algorithm in ATT7022E 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 simula-tion, this harmonic analysis method has certain reference value in engineering application.
