A WT based high resolution approach to quantify single-phase power components defined in IEEE STD 1459-2010

This paper presents a high resolution approach based on wavelet transform (WT) for measurement of single phase power quantities defined in IEEE STD 1459-2010 specially in case of non-sinusoidal conditions of voltage and current waveforms. The proposed approach is divided into two stages, firstly using the advantage of discrete wavelet transform (DWT) in order to calculate the phasors (magnitude and phase angle) of fundamental frequency component of non-sinusoidal voltage and current waveforms, secondly using the advantage of discrete wavelet packet transform (DWPT) in harmonic analysis of non-sinusoidal waveforms in order to calculate RMS values of integer harmonics. Unlike existing approaches, the proposed approach provides higher resolution level of harmonics RMS values estimation. The developed approach is tested with the synthesised waveforms and obtained results are compared with results of the other methods.
