An application of continuous wavelet transform (CWT) for the analysis of voltage flicker-generated signals is proposed. With the time-frequency localization characteristics embedded in wavelets, the time and frequency information of a waveform can be integrally presented, thereby enhancing the monitoring of voltage flicker-generated signals at different time intervals. The Morlet wavelet has been selected as the basis function for the CWT in the proposed method. The merit of the method lies in that the signal component at any frequency of interest can be more easily monitored than by discrete wavelet transform (DWT). The high frequency required in the voltage flicker study can be also comfortably accomplished. This approach has been applied to investigate various simulated voltage flicker-generated signals, and inspect the data recorded from the actual arc furnace operation. Test results help solidify the practicality and advantages of the proposed method for the applications.
