Abstract: A generator for a wind turbine has a rotor and a stator separated radially by an air gap, wherein the stator includes at least one stator segment, which includes a stack of lamination sheets and at least one stator winding, and a stator support structure supporting the at least one stator segment, wherein the generator further includes a cooling arrangement for providing cooling fluid at least to the air gap, wherein the cooling arrangement further includes a cooling fluid flow dividing element for dividing an incoming cooling fluid flow to the stator into a first partial cooling fluid flow directed to the air gap and a second partial cooling fluid flow directed to the stator support structure.

Abstract: Provided is a control device configured to control a wind turbine, the wind turbine including a rotor being rotatable about a rotational axis, wherein the rotor has at least one blade, the blade including at least one add-on member which is actuated by a corresponding trim actuator to alter aerodynamic properties of the blade and a pitch actuator to alter a pitch angle of the blade. The control device is configured to determine an idling mode or a self-sustaining mode of the wind turbine; to control the pitch actuator to set a predetermined pitch angle of the blade, if the idling mode or the self-sustaining mode is determined; and to cause a target rotational speed of the rotor by variably controlling the trim actuator of the blade, if the idling mode or the self-sustaining mode is determined.

Abstract: Provided is a wind turbine having at least one lighting device, which has a light source and emission device, wherein the light source and the emission device are arranged at different positions of the wind turbine, wherein at least one positioning device is provided which, by a positioning section, is coupled to the emission device in such a way that the emission device can be moved between a first position and a second position by a movement of the positioning section.
