Embodiment Construction

[0023] The same or similar elements may be provided with the same or similar reference numerals. Furthermore, the description as well as the claims contain several features in combination. It is obvious to a person skilled in the art that these features can also be considered individually or that these features can be combined in other combinations not described in detail here.

[0024] figure 1 A diagram of a wind energy installation 100 with a control device 102 according to an exemplary embodiment of the invention is shown. Control device 102 has means 104 for reading and means 106 for providing.

[0025] The wind energy installation 100 has a tower 108 on which a generator nacelle 110 is mounted so that it can rotate horizontally. Arranged within the generator nacelle 110 or the nacelle 110 is a generator which is driven via a rotor shaft by a rotor 112 of the wind energy installation 100 . The rotor 112 is arranged axially relative to the generator. A transmission ma...

Abstract

The invention relates to a method used for adjusting a rotor (112) of wind energy equipment (100) according to wind direction; the method comprises a step of providing adjusting signals (126) for the rotor (112); the adjusting signal (126) for each rotor blade (114) of the rotor (112) represents a single periodical matching deflection-attach angle portion, thus causing a deflection torque (128) generated by wind and used for tracking and adjusting the rotor (112).

Description

technical field [0001] The invention relates to a method for adjusting a rotor of a wind energy installation according to wind direction, to a corresponding control device, to a wind energy installation and to a corresponding computer program. Background technique [0002] In wind power installations, the plane of the rotor should always be oriented as perpendicular as possible to the ground through which the wind passes, in order to achieve an optimal power capture. Due to the perpendicular orientation of the rotor to the wind direction, the asymmetric load on the rotor is also reduced, thereby reducing the load on the installation as a whole. [0003] However, the centrifugal forces generated by the rotating rotor do not allow frequent adjustments of the wind turbine. This centrifugal force causes additional loads on the supports of the main shaft as well as on the tower head bearings. The orientation of the wind turbine is therefore only tracked if the measurement error...
