Abstract :
This paper presents a unique comparison between Wavelet Packet Transform (WPT) and Discrete Wavelet Transform (DWT) in the power system harmonics scenario. The signals used are actual tested waveforms which have been obtained using power quality analyzer. The results obtained using WPT and DWT are then compared with IEEE Standard 1459 - 2000 based values. The percentage error has been calculated for the individual parameters in both the cases. The comparative study shows DWT to be more suitable over WPT for quantization of power system harmonics.
