“…7 and Table 4. From the figure and table, although RifeVincent 4-I window exhibits the highest sidelobe decay rate among all cosine windows, it can be concluded that when it is taken amplitude and phase angle together the proposed Nuttall-Kaiser combination window has better performance than others [24].…”

Harmonics pose a great threat to safe and economical operation of power grids. Therefore, it is critical to detect harmonic parameters accurately to design harmonic compensation equipment. The fast Fourier transform (FFT) is widely used for electrical popular power harmonics analysis. However, the barrier effect produced by the algorithm itself and spectrum leakage caused by asynchronous sampling often affects the harmonic analysis accuracy. This paper examines a new approach for harmonic analysis based on deducing the modifier formulas of frequency, phase angle, and amplitude, utilizing the Nuttall-Kaiser window double spectrum line interpolation method, which overcomes the shortcomings in traditional FFT harmonic calculations. The proposed approach is verified numerically and experimentally to be accurate and reliable.K e y w o r d s: power system, harmonic analysis, barrier effect, window function, FFT
