... to develop a phasor estimation technique fulfilling the performance criteria at low sampling frequency. Design/methodology/approach To provide high accuracy during off-nominal frequency estimation, this work attempts to enrich the attenuation level at the side-lobe using a five-term cosine function...

...Seyed Reza Aali; Mohammad Reza Besmi; Mohammad Hosein Kazemi Purpose The purpose of this paper is to study variation regularization with a positive sequence extraction-normalized least mean square (VRP-NLMS) algorithm for frequency estimation in a three-phase electrical distribution system...
