| Abstract: | This paper presents the time-frequency analysis method for detecting disturbance in power quality analyzing. The Meyer wavelet is applied for detecting the swells, sags, interruptions, transients and notches in power quality analysis. The result of simulation illustrates that Meyer wavelet has good performance in time-frequency detecting. |
