Abstract
A method for controlling a tip speed of a blade of a wind turbine. The method includes determining the wind speed proximate the wind turbine; maintaining a first substantially constant rotational speed of the tip of the blade during variable wind speeds above a first predetermined nominal wind speed and below the second predetermined nominal wind speed; maintaining a second substantially constant rotational speed of the tip of the blade during variable wind speeds above a second predetermined nominal wind speed. The noise generated by wind at the second predetermined nominal wind speed is greater than noise generated by the blade at the second constant rotational speed of the tip of the blade.
