The present application relates to a generator comprising: a stator, a rotor, in particular having a rotor band, and a heat pipe assembly which is thermally connected to the rotor in order to conduct heat which is generated by the rotor, in particular during operation of the generator.

Generator of a wind turbine

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.

Wind turbine and method for controlling a wind turbine

A wind turbine rotor blade, with a length, a rotor blade root, a rotor blade tip, a pressure side, a suction side, a leading edge, a trailing edge, and an air guide for heated air to guide heated air inside of the rotor blade and along a longitudinal direction of the rotor blade from the rotor blade root in the direction of the rotor blade tip. The wind turbine rotor blade additionally comprises at least one passively controllable air control element in the area of the air guide. The invention further relates to a wind turbine with at least one wind turbine rotor blade.

Wind turbine rotor blade and wind turbine

Method for operating a wind power installation which has a rotor and feeds an output power from wind, the latter having a wind speed, into an electric supply grid, and controls cooling of a component of the wind power installation, wherein an operational evaluation is carried out, in which an operating state or an operating state variation is evaluated, and the cooling is controlled as a function of a component temperature and additionally as a function of the operational evaluation.

Method for efficiently cooling a wind power installation

A wind turbine rotor blade is provided comprising a rotor blade root region, a rotor blade tip region, a pressure side, a suction side, a front edge, a rear edge and at least one web along a longitudinal direction of the rotor blade. Furthermore, a deflecting unit is provided comprising at least two deflecting bends between one end of the at least one web and the rotor blade tip region.

Wind turbine rotor blade

Air cooling device for the air cooling of a generator of a wind power installation by means of wind, comprising a cooling unit of the generator with a cooling unit outer surface, the wind flowing onto said cooling unit outer surface for the air cooling of the generator during the operation of the wind power installation, wherein an air deflector is arranged on the cooling unit outer surface of the cooling unit and has a first air deflection unit which extends outwardly at an acute angle starting from the cooling unit outer surface and forms with the cooling unit a converging first air deflection channel, which is configured in an operating state of the wind power installation to deflect the wind for the air cooling in the direction of the cooling unit.

Air cooling device, generator, air guiding device, wind power installation and method for producing a generator and a wind power installation

The invention relates to a method for determining the energy production to be expected for a wind power installation for a forecast time period, which may be an expected annual energy production. The installation has installation components. In the method, at least one of the installation components is selected as a thermally relevant component and chronologically distributed wind speed values are specified for the forecast time period. An expected power output level of the installation is determined for one of the wind speed values. In the power output level determining step, a component temperature which is assigned to this wind speed value is taken into account by the at least one thermally relevant component. The expected power output level of the installation, which is determined for the wind speed value, is used to determine the energy production of the installation which is to be expected for the forecast time period.
