Abstract
In this paper a Cascaded Doubly-Fed Induction Generator (CDFIG) has been modeled using the Power-Oriented Graphs (POG) technique. The dynamic equations of the system have been obtained using a Lagrangian approach. The system equations have been described with respect to a rotating reference frame to clearly show the internal dynamic structure of the system. An Indirect Rotor Field-Oriented control that let the grid voltage frequency to be constant, even when the rotor speed is variable, has been given and implemented. Finally, some simulation results have been reported to validate the presented control law and the effectiveness of the model.
