摘要
采用型号为STM32F407VGT6的ARM单片机和AD7606模数转换芯片设计了电网谐波监测装置,利用全波傅里叶算法计算采样数据,求出电压、电流量的基波幅值、高次谐波含量以及总谐波畸变率。将换算后的最终结果,通过GPRS无线通信发送到固定IP地址的服务器。试验结果表明:该装置硬件电路结构简单、易于实现,能满足实际工程应用的要求。
By using the ARM microcontroller of STM32F407VGT6 and the AD7606 digital conversion chip thispaper designed an electric harmonic monitoring device. The full wave Fourier algorithm is used to calculate thesampling data, the fundamental amplitude, harmonic content and total harmonic distortion rate of the voltage andcurrent are calculated. After converting, the final results, through the GPRS wireless communication, are sent to afixed IP address smwer. The experimental results show that the hardware circuit of the device is simple and easy toimplement, and can meet the requirements of practical engineering application.
