Abstract: A wind turbine with a tower and a nacelle with a nacelle housing is provided. The nacelle is placed on the tower. Further provided is a cooling flap, which is configured to close an opening in or on the area of the wind turbine to be cooled. At least one temperature-dependent passive actuator is configured to activate and open the cooling flap as a function of temperature, so as to enable a heat compensation in the area to be cooled by means of the opening. The temperature-dependent passive actuator can change its shape and/or its length without any external electrical energy as a function of temperature.

Abstract: A generator for a wind power installation for generating electrical energy from kinetic energy comprises an outer peripheral surface portion, the outer peripheral surface portion having: an incident-flow surface portion against which wind flows in an incident-flow direction in the installed state of the generator, the incident-flow surface portion extending along an axial direction and orthogonally thereto along a peripheral direction, and a cooling surface portion, designed for cooling the generator and disposed downstream of the incident-flow surface portion in the installed state in the incident-flow direction, the cooling surface portion extending along an axial direction and orthogonally thereto along a peripheral direction, wherein one or more vortex generators for passive cooling of the generator are arranged in a region of the outer peripheral surface portion, in particular in a region of the incident-flow surface portion and/or in a region of the cooling surface portion.

Abstract: A wind turbine comprising a tower, a nacelle arranged on the tower, a generator, and a rotor comprising at least one rotor blade, wherein the wind turbine comprises vortex generators arranged on an outer surface of the tower, wherein the vortex generators have a fin extending from the outer surface of the tower, and wherein the fin has a height extending perpendicularly from the surface of the tower and a fin chord extending parallel to the surface of the tower. The fin chord has a curvature such that a first end of the fin chord has a smaller angle to the horizontal than the opposite second end of the fin chord.

Abstract: A method for ascertaining a wind direction at a wind power installation having a rotor on which at least one rotor blade is arranged. The method includes measuring first wind speeds in a predefined first measuring direction and second wind speeds in a predefined second measuring direction different from the first measuring direction in each case with a measuring frequency at a measuring point for a measuring period, wherein the measuring period is defined by a rotational distance of the rotor or by a prespecified time, wherein the rotor blade or one of the rotor blades passes the measuring point in the measuring period, and determining a wind direction by vectorial evaluation of the first wind speeds and of the second wind speeds.
