Abstract	Power system harmonics are inevitable in the presence of non-linear loads. The presence of harmonics has a greater impact on the terminal apparatus. Accurate analysis of Power system harmonics plays an important role to have a better mitigation. Windowed Interpolated FFT (WIFFT) based algorithms are gaining importance due to their accurate analysis. The major advantage of WIFFT based algorithms includes reduction in error due to spectral leakage and picket-fence effect. This paper represents the application of improved Hanning window based Interpolated FFT (IFFT) algorithm for harmonic analysis. The proposed algorithm is used to analyze a static simulated signal in MATLAB. The simulation results shows the effectiveness of Hanning window based IFFT compared to Hamming window based IFFT. The algorithm is also used to analyze a dynamic signal simulated in LabVIEW and its potential towards online tracking of a signal.
