Electric power quality is an aspect of power engineering that has been with us since the inception of power systems. To investigate this issue, engineers have proposed various schemes to deal with the power disturbance waveforms. Among these approaches, wavelet transform is one of the most frequently used algorithms to analyze the power signal. This paper presents a new design of discrete wavelet transform suitable for DSP-based implementation. This approach has the advantages of low cost, real-time calculation, and possible hand-held device implementation. In addition, the experimental results demonstrate accurate disturbance time localization and clear decomposition of power disturbance signals.
