Doubly Fed Induction Generators (DFIG) are as the main generators which are used in the power generation systems of wind energy in Variable Speed-Constant Frequency (VSCF). Wind turbine model and dynamic mathematic model of DFIG have been presented in this article. Rotor currents control in internal loop and rotation speed in external loop have been accomplished according to the methods of Internal Model Control (IMC). A sample of Doubly Fed Induction Generators of VSCF with nominal capacity of 1.5 MW has been simulated in MATLAB software. The simulation results indicate quick dynamic response of system in different conditions and performance in hyper-synchronous and sub-synchronous speed.
