| Abstract: | In view of the increasingly serious harmonic pollution in rural areas, this paper adopts fast Fourier (FFT) algorithm based on the hanning window in Matlab environment. The method will reduce the problem of fast Fourier transform spectral leakage, and improve the accuracy of the harmonic analysis of power grid. The simulations show that the results would be better when using the fast Fourier transform algorithm which adds hanning window to measure the power network harmonic. |
