Computerized Modeling of Variable Speed Wind Turbines and developing its control systems


Abstract in English

The turbine control purpose is to achieve the maximum limit of wind power, associated with reducing the mechanical loads. The current control techniques do not take into consideration the dynamical side of wind and turbine, which leads to power loss. To improve the effectiveness of the nonlinear controllers, we can derive the nonlinear feedback controllers for static and dynamic conditions in order to reach the wind speed estimator. Then we can test the controllers by a mathematical model applied on the wind turbine simulator, with disturbances and noise. The results have shown important improvements in comparison with the current used controllers.
