Abstract :
This paper proposes the estimation of active power, reactive power, apparent power, and power factor using the scaling and the wavelet coefficients of the Maximal Overlap Discrete Wavelet Transform (MODWT). The performance of the proposed wavelet-based power measurement was assessed and compared with the IEEE Standard 1459-2010 and the power estimation through the Discrete Wavelet Transform (DWT). As advantage, the MODWT provides power estimation every sampling, which is ideal for real-time analysis.
