Abstract:Matrix Pencil Method (MPM) has been applied to sub-cycle information of space vector and zero-sequence voltage to classify voltage dip phenomena. The feature extraction performance of MPM using different sampling window width has been statistically analyzed and found to perform relatively well between 0.1 and 1 cycle of a damped complex sinusoidal signal. The results show that MPM is able to estimate the fundamental frequency space vector even in highly distorted signals. The space vector ellipse's estimation … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
