Abstract: A wind turbine tower includes a door access opening in a down tower area of the tower. A hinged door panel covers the door access opening, with a ventilation opening defined through the door panel. A multi-sided intake structure, such as a box-like structure, is connected to an exterior of the door panel over the first ventilation opening. The intake structure extends transversely from the door panel and includes a top side, a bottom side, and at least two vertical sides extending between the top side and the bottom side. The vertical sides are open to air flow therethrough. The top and bottom sides may also be open to air flow therethrough. Air from multiple directions is drawn into an interior of the wind turbine tower through the intake structure and ventilation opening. A filtering system with first and second stage filters may be incorporated with any of the intake structures.

Abstract: A method for installing an add-on device onto a blade of a wind turbine includes configuring a plurality of tag lines to a wrap, the tag lines having a length to extend to a ground location when the add-on device is positioned on the blade. With the rotor, positioning the blade to a first rotated position. The add-on device is located at a desired span-wise location on the blade such that the wrap forms an open-sleeve configuration draped around the leading edge of the blade and span-wise sides of the wrap extend along pressure and suction sides of the blade adjacent a trailing edge of the blade. With the tag lines, the wrap is tensioned against the blade. Attachment devices configured with the wrap are affixed to the trailing edge of the blade.

Abstract: A method is provided for installing a continuous pliant add-on device (e.g., a vibration suppression device) onto a blade of a wind turbine, wherein the blade is mounted to a rotor that is atop a tower. The method includes, with the rotor, positioning the blade to a first position. A first end of the add-on device is fixed to a first end of the blade. The blade is then rotated with a pitch control system while supplying the add-on device in a first direction along a span of the rotating blade to wrap the add-on device around the blade towards an opposite second end of the blade in a first wrap pattern.

Abstract: A system and method are provided for reducing vibrations and loads in one or more rotor blades of a wind turbine when the rotor hub is locked against rotation, The method detects that the rotor blades are vibrating above a threshold limit, and determines one or more wind parameters for wind impacting the rotor blades. An initial orientation of the blades is also determined. Based on the wind parameters and initial blade orientation, a first angle of attack for the rotor blades is determined that will reduce the vibrations in the rotor blades. The method then determines if expected loads induced at one or more wind turbine components will exceed a threshold limit at the first angle of attack for the rotor blades. The first angle of attack is modified when the expected loads exceed the threshold limit to reduce the expected loads to below the threshold limit. A controller pitches the rotor blades to achieve the first angle of attack.
