This thesis deals with the stabilization of grid connected wind farms by doubly fed induction generators (DFIGs). The fast growth of wind generation has led to concern about the effect of wind power on the transient stability of the electric grid. As the amount of wind power is drastically increasing in years to come, maintaining power system stability during, for example, a short circuit fault will be more important in order to ensure power supply reliability and other important issues. New studies must be performed in order to evaluate the behavior of the wind farms after severe faults and improve the design of the wind farms in an efficient and economical way. Under such circumstances, the most demanding requisite for wind farm is the Fault Ride-Through (FRT) capability. Wind farms connected to high voltage transmission system must stay connected when a voltage dip occurs in the grid, otherwise, the sudden disconnection of great amount of wind power may contribute to the voltage dip, with terrible consequences. Therefore, the dynamic and transient analyses of wind generators are necessary, in order to improve the FRT of wind farms....
