Space vector modulation technique applied to doubly fed induction generator

Abstract

In this paper, implementation of SVPWM switching technique for a constant frequency, variable speed wind turbine is carried out. The modeling and simulation is done using MATLAB/Simulink for doubly-fed induction generator. The total harmonic distortion for various parameters like stator current, rotor speed and electro-magnetic torque of this wind electric generator has been obtained. The reduction in distortion level is higher compared to other pulse width modulation techniques.
