초록

The wavelet transform can apply various lengths of windows according to the amount of signal frequencies. So characteristics of nonstationary disturbances were found to be more closely monitored by the wavelet transform. In this paper, the wavelet transform is applied to the algorithm for monitoring various power quality disturbances. And personal computer monitoring system was developed.
