Method for operating a wind turbine, arrangement and system

摘要

A method is provided for operating a wind turbine having an elongated stand apparatus, a generator rotatably mounted on the stand apparatus, and a rotor coupled to the generator via a rotor hub and the wind turbine also having an elongated rotor blade. A position of a radar system is determined with respect to the wind turbine and at least one area is determined for the rotational axis of the rotor as a function of the determined position which is not intended to be permanently assumed for alignment of the rotational axis of the rotor about the longitudinal axis of the stand apparatus. The wind turbine is operated with the at least one determined area not being permanently assumed for the alignment of the rotational axis of the rotor about the longitudinal axis of the stand apparatus.

1. A method for operating a wind turbine, comprising the steps of:
providing the wind turbine including an elongated stand apparatus, a generator rotatably mounted on the stand apparatus, and a rotor which is coupled to the generator via a rotor hub and has an elongated rotor blade; determining a position of a radar system with respect to the wind turbine; determining at least one area for aligning the rotational axis of the rotor in the direction of the generator as a function of the determined position of said radar system which is not intended to be permanently assumed for alignment of the rotational axis about the longitudinal axis of the elongated stand apparatus; operating the wind turbine with the at least one determined area not being permanently assumed when the rotational axis of the rotor is aligned about the longitudinal axis of the elongated stand apparatus; determining a wind direction of the wind flowing over the wind turbine; determining a value for the alignment of the rotational axis of the rotor as a function of the determined wind direction; and, aligning the rotational axis of the rotor with an edge of the area which is not intended to be permanently assumed for alignment of the rotational axis of the rotor about the longitudinal axis of the stand apparatus, when the determined value is in the area not intended to be permanently assumed for an alignment of the rotational axis of the rotor about the longitudinal axis of the stand apparatus.
