The algorithm of interpolating windowed FFT for harmonic analysis of electric power system.

The algorithm of interpolating windowed FFT for harmonic analysis of electric power system.

The fast Fourier transform (FFT) cannot be directly used in the harmonic analysis of an electric power system because of its higher errors, especially the phase error. This paper discusses the leakage phenomenon of FFT and presents a new amending algorithm, poly-item cosine window interpolation, whi...
