| Abstract: | This paper introduced a Maflab simulation model of smart meter based on fast fourier transform （FFT） algorithm for analysis of electric power harmonics, which can calculate precise electrical parameters, including the power factor, harmonic component, distortion and so on. The model consists of waveform generator of power system, signal conditioning module and microchip module and can analyze harmonic for theoretical data, simulating data of power system and fieldes test data. This paperes focus on the FFT data processing module. Through the Matlab software＇ s own power parameter calculation module, the results of FFT Analysis function of Matlab software Powergui module and the simulation model, were compared and the correctness of this method was verified. |
