Abstract
The invention relates to a method for the operation of a wind energy plant (), wherein the wind energy plant () has a rotor () with a rotor axis and at least one rotor blade (') arranged on the rotor (), wherein the rotor blade (′) is adjustable or adjusted around a rotor blade axis with a predetermined rotor blade pitch angle. Further, at least one rotor blade (′) is rotated into an idle position, the rotation of the rotor blade (′) is braked after a first predetermined rotational position of the rotor blade (′) is reached and the stand-still position of the rotor blade (′) reached as a result of the braking procedure is captured. Furthermore, the invention relates to a wind energy plant () with a rotor () and at least one angle-adjustable rotor blade (′) arranged on the rotor ().
