Comportamento dos geradores de indução duplamente alimentados em turbinas eólicas de 1,5MW

Abstract

Among the different ways to generate wind energy, one is the use of an induction machine with a wound rotor, where it is doubly-fed by the electrical system, being fed directly in the stator and in the rotor through converters. This paper presents the simulation study and these generate energy. The reason this method has been used in wind generation was about the possibility to provide electrical power to the network system at constant frequency and using different rotation speeds of the machine. This method is widely employed because in wind generation is interesting when the generator allows operating at different rotation speeds, in this way the turbine can work in high efficiency for different wind speeds. Consolidated data of the simulation using MATLAB software will be shown at the end of the work.
