Procedure and regulation device for a wind energy installation, as well as a computer program product, digital storage medium and wind energy installation

摘要

Procedure for the operation of a wind power installation (1000), in which, in a case of technical assistance or similar case of a disconnection of the wind power installation conditioned by the operation, the rotor (3) stops and immobilizes , which presents the stages; - rotor braking (3) - rotor positioning (3) in a stop position, - rotor immobilization (3) in the stop position (P1, P2), in which - a position (S2) is also predetermined final - the rotor (3) is braked (SI) in a regulated manner to a stop position associated with the final position, and - in view of the positioning (S-II) for the predetermined final position, the rotor is automatically braked until the stop in the stop position, in which - for immobilization (S-III) and / or lock in the stop position a mechanical immobilization device is approached, characterized in that the stop position is adjusted (S6) with the use of a generator retention moment as a retainer for immobilization and / or a block, a final position of the rotor being predetermined while an angular position of the rotor is predetermined and the angular position is associated with a position of retention of the generator .
