Design and Modelling of Induction Generator Wind power Systems by using MATLAB/S IMULINK

G. Hima Bindu, Dr. P. Nagaraju Mandadi

This paper describes the performance comparison of a wind power systems based on three different induction generators. The three induction machines studied for the comparison are the squirrel-cage induction generator (SCIG), the doubly fed induction generator (DFIG) and using a doubly fed induction generator in single-sided grid connection. The performances are compared between the SCIG, DFIG and DFIG in single-sided grid connection systems. The SEF-DFIG stator of the machine is connected with a direct power grid, and the rotor is controlled by an inverter without any external power source. In this paper, for applying the proposed scheme to the wind turbine, the design and modelling of the induction generators simulated in MATLAB/SIMULINK environment
