| Abstract： | In this paper, the window fast Fourier transform (FFT) was studied, and FFT was improved using interpolation method, and this paper proposed an effective interpolation method based on harmonic elimination method. By comparison between theoretical knowledge and the simulation experiments, it was proved that the improved method can effectively alleviate formation of leakage and barrier effect. This method can be used to accurately read every harmonic amplitude and phase, which is of great help for every harmonic analysis in the future, and provides convenience for harmonic governance and management. |
