Uma Proposta De Experimento De Laboratório Para O Ensino Didático De Distorção Harmônica

Abstract

Harmonic distortions are anomalies in the electrical grid that consist of distortions of the sinusoidal signal, the resulting signal from the distortion can be decomposed into harmonics, of sinusoidal signals multiples of the fundamental frequency. The study of harmonic distortions is necessary for understanding the aspects involved in energy quality, which affect the entire electrical system and its equipment. This work will focus on the theory about harmonics and harmonic distortions, with a didactic purpose for students of bachelor’s degree courses in electrical engineering. It will address the aspects of calculations, analysis, and limits of the harmonic components in the voltage and electric current signal. To conduct practical studies, the harmonic distortions in converters will be analyzed, describing the assembly, measurement, and analysis of the data, verifying the harmonic distortions present in the signal.
