PWM controlled double-fed induction generator for wind energy applications

Abstract

In this paper, a wind power system using a double fed induction generator (DFIG) was modelled and simulated by using MATLAB/Simulink environment. At the beginning of the study DFIG and its control methods are introduced. After simulative approaches, it will be aimed that how DFIG response to speed changes in different load conditions with pulse width modulation (PWM) control method. The system is analyzed in terms of electromagnetic torque, rotor speed, voltage, current and control signals at constant DC Link voltage.
