Damping of Wind Turbine Tower Oscillations through Rotor Speed Control

To enable wind turbines to produce power under great variety of wind conditions a sophisticated control system is needed. Wind turbine system is highly nonlinear and its dynamic changes rapidly with the change of wind speed. Besides this, wind turbine mechanical structure is very flexible due to its great height and tends to oscillate. All this makes the design of wind turbine control system very demanding task. In his paper three controller design methods are compared. It is shown how with adequate controller design it becomes possible to control the wind turbine under various operating conditions reducing the structural oscillations at the same time
