Análise comparativa de técnicas de estimação de harmônicos em sistemas de potência.

Abstract

The determination of harmonic components present in a signal is of fundamental importance for studies in power quality in power systems. Several techniques are used to extract the harmonic content in signals. This paper presents a comparative analysis between some few techniques that are used for estimation of harmonic components. Results based on both simulation and experimental setups are presented in order to evaluate the performance of the proposed techniques.
