Distance protection using a novel phasor estimation algorithm based on wavelet transform

This paper presents a novel phasor estimation algorithm, which combines the filtering characteristics of the maximal overlap discrete wavelet transform (MODWT) and the least error square (LES) algorithm. Time and frequency response of the designed filters are compared to the ones of traditional disc...
