Problems solved by technology

[0005] The disadvantage here is that energy is required for this readjustment
Furthermore, the forces generated are so great that the usual high tracking speed and low energy consumption are ruled out

Embodiment Construction

[0024]The wind energy installation 10 comprises a carrier installation, such as in particular a tower 12 , at the upper end of which a so-called gondola 14 is arranged. The gondola 14 has a housing 16 , inside which typically different technical units (not shown here), such as in particular a transmission, a generator, a control device, etc., are arranged.

[0025] As an essential element, the nacelle 14 carries a rotor 20 , which here has two rotor blades 22 and 24 , which are fastened on one side to a central rotor hub 26 . The rotor 20 is configured to rotate in the wind, thereby driving a corresponding generator to generate electrical energy. For this purpose, the cross-section of the rotor blades 22 and 24 has the shape of an airfoil. The direction of rotation of the rotor 20 is figure 1 are indicated by corresponding arrows. In this case, rotor 20 rotates about rotor axis 28 in a plane formed by rotor blades 22 , 24 and a straight line which simultaneously extends per...

Abstract

In wind power plants (10), deviations from the optimal operating state lead to power losses. This applies in particular to angular deviations (62) in the orientation of the gondola (14) and therefore of the rotor axis (28) relative to the wind direction (60). The invention relates to a wind power plant (10) and to a method for operating such a wind power plant (10) by means of which wind force-based motorized tracking of the gondola (14) in relation to the wind direction is made possible.

Description

technical field [0001] The invention relates to a method for operating a wind energy installation according to the preamble of claim 1 . Furthermore, the invention relates to a wind energy installation according to the preamble of claim 9 . Finally, the invention relates to a control device for a wind energy installation according to the preamble of claim 12 . Background technique [0002] Modern wind energy installations are characterized by high power and thus corresponding structural dimensions. In recent years, the size of the rotor diameter of several meters and the initial power of tens to hundreds of kilowatts of these facilities has developed to the rotor diameter of more than one hundred meters and the power of several megawatts per facility at present. Furthermore, wind energy installations are today not only erected on land (onshore), but increasingly also high above sea (offshore). In addition to technical developments in the field of transmission and generato...
