Rotation Speed Control of Horizontal-Axis Wind Turbine by Tip Vane

抄録

This paper describes the rotation speed control of a horizontal-axis wind turbine. A tip vane has the excellent capability of improving the performance of the horizontal-axis wind turbine. Also, we found that the rotation speed of the wind turbine is controlled by changing the sweep angle of the tip vane. The relationships among the sweep angle of the tip vane, the change of wind speed and the rotor speed are investigated. As a result, a method to maintain constant rotor speed for changing wind speed, by means of an electromechanical apparatus, is developed.
