Abstract
The paper investigated the problem of spectrum leakage in harmonics detection of power system based on FFT,analyzed the causation of spectrum leakage and put forward a solution method of spectrum leakage with window functions.The simulation result showed that Hann windows can reduce spectrum leakage commendably and satisfy accuracy of harmonic detection.
