Abstract :
In this paper, the performance of discrete wavelet transform (DWT) is investigated. Impact of the type and order of the mother wavelet, sampling frequency, and the signal waveform on the DWT performance is evaluated in the scope of power system protection requirements. A novel DWT computation algorithm is introduced in order to eliminate the complexity encountered in real-time implementation. Efficacy of the proposed algorithm is verified via digital signal processing (DSP) experimental tests. The results consolidate the possibility of efficient DWT real-time implementation even with higher sampling rates. Shortcomings of DWT application to power system protection are outlined and corrective recommendations are included
