Problemas de Medições em Analisadores de Energia Elétrica Devidos a Supra-Harmônicas Produzidas por Conversores Eletrônicos de Potência
Keywords:
Power quality, supra-harmonics, microgrids, power electronics
Abstract
The article presents problems of harmonic identification in networks with the presence of power electronics converters with high switching frequency. It begins with a description of the standardized procedures for the operation of energy analyzers. The following shows how the presence of high frequency components can occur in currents and voltages signals. Finally, it is verified how such components can affect the correct spectral identification of the energy analyzers. Simulation results and field measurements are presented.
