Análise e modelagem no domínio da fase da máquina de indução trifásica de rotor bobinado operando sob distúrbios de tensão

Abstract

This work contributes to the study of the three-phase wound-rotor induction machine driven as a generator, both experimentally and through computer simulations, under normal operating conditions and when subjected to electrical disturbances, such as: unbalance, harmonic distortions and voltage variations. The main objective is to verify the response of the mathematical modeling of the three-phase induction machine used, called a model in the phase domain, which, in addition to not employing transformations of coordinates or reference systems, includes the effects of magnetic saturation. In order to reach the main objective, an experimental test platform was developed to provide data such as voltages, currents and mechanical speed, to be confronted with those obtained theoretically. At the end of the study, it was observed an adequate compatibility of the results from the computer simulations, with those obtained experimentally, for all the case studies carried out.
