The thesis discusses modeling and control of wind turbine systems (WTS) with doubly-fed induction machines (DFIM). A holistic model design yields the dynamic power flow within the WTS. Based on a nonlinear DFIM model including flux maps and differential inductances, new control strategies are employed to regulate the machine. A back-to-back converter connects the WTS to the grid via an LCL filter. The controller design of the grid connection under harsh system conditions is developed. Measurements validate both modeling of the WTS and control performances.
