| Abstract: | This paper designs a power parameter detection device based on STM32F103VE6 and ADE7878,using the electric energy measurement chip ADE7878 to sample many parameters including voltage,current,frequencies,power factor,and so on.With ARM STM32F103VE6 chip as CPU,by connecting CPU SPI port to ADE7878’s high speed data capture interface,the AD conversion data of the current and voltage waveform is transmitted to CPU with high-speed.After CPU gains access to the data and saves it in real time,frequency quasi-synchronous conversion and FFT computation are completed to achieve the measurement of harmonics.The device has the function of the accurate measurement of the public distribution network voltage,current,active power,reactive power,harmonics and other parameters,which can provide an effective on-line monitoring tool for the public distribution network for energy monitoring,reactive power compensation and harmonic control. |
