Wind farm based doubly fed induction generator using a novel AC/AC converter

This paper proposes the use of a novel three-phase PWM rectifier-inverter topology for doubly fed induction generator (DFIG) applications. The topology uses only nine IGBT devices for ac/ac conversion through a dc link. As compare to conventional back-to-back ac/ac converters, the numbers of power semiconductor switches are reduced in the suggested converter. The proposed topology results in reduction of installation area and cost. The operating principle, control strategy and characteristics of DFIG based proposed ac/ac converter is described in this paper. The performance of proposed DFIG is validated with simulation results using MATLAB/SIMULINK software.
