Simulation of a Wind Turbine with Doubly-Fed Induction Machine Using FAST and Simulink

In order to fully study the electrical, mechanical and aerodynamic aspects of a wind turbine with a doubly-fed induction machine (DFIM), a detailed model that considers all these aspects must be used. In general, however, detailed electrical models are combined with very simple mechanical and aerodynamic models or vice versa, so that the effects of interactions between all three aspects are neglected. In the paper, three simulation programs - TurbSim, FAST, and Simulink - are used to model the wind, mechanical and electrical parts of a wind turbine and its controllers in detail. Simulation results obtained from the model are used to observe the interaction of all three aspects of a wind turbine system
