| Abstract: | Wavelet transform has the characteristic of time-frequency localization and has been applied widely in electric power systems. Harmonic detection to the electric power systems based on wavelet transform and the measurement of voltage flicker using wavelet transform with synchronous detection are proposed in this paper. It has been proved that this method can be used to detect the voltage flicker exactly by simulation. |

| Keywords: | electric power system wavelet transform voltage flicker synchronous detection |
