Análise teórica da máquina de indução duplamente alimentada atuando como gerador eólico.

Abstract

A source of energy sought as a source of renewable energy, which uses as sources of clean and renewable energy for other forms of electrical energy. In this year it was observed a growth of sources, mainly, that are generators of other renewable energy sources, mainly the ones that are generators of other renewable energy sources, have several advantages, of energy sources, of their source costs, which are energy generators and source costs. system-wide, there is regular availability of offshore power and ease of installation. Thus, to contribute to this scenario, the work demonstrates and introduces an analysis of the Machine Theory presented of Doubly Fed production, as a Wind Generator. A DFIG study was carried out and a mathematical modeling and computational simulation were presented in Matlab®/SimulinkTM. The mathematical approach used was used in the modeling of the turbocharged mechanism and doubly fed generator (DFIG) as they were approved. A vector control strategy used for air load control and air force compensation, demonstrating the control of aerodynamic current from load distortion. The machine side controller is used to attenuate harmonics and common voltage and current at the connection point. Finally, the work aims to build a simulation model of DFIG in the MATLAB environment. The simulation results show the performance of stator and rotor currents in all three modes. The accuracy of the mathematical modeling can also be verified through the simulation results.
