Abstract: Starting from wind turbine model types and structures, this paper introduced wind turbine’s aerodynamic model, generator model,converter model and controller model. With the double-fed induction generator as an example, analysis was made to its speed controller and pitch controller principle and its control process. This paper established a more complete wind turbine model to provide basis for design and control of wind turbines.
Key words: wind turbine; controller; aerodynamics; double-fed induction generator
