Abstract

The invention relates to a method for the operation of a wind energy plant (10), wherein the wind energy plant (10) has a rotor (11) with a rotor axis and at least one rotor blade (15, 15′) arranged on the rotor (11), wherein the rotor blade (15, 15′) is adjustable or adjusted around a rotor blade axis with a predetermined rotor blade pitch angle. Further, at least one rotor blade (15, 15′) is rotated into an idle position, the rotation of the rotor blade (15, 15′) is braked after a first predetermined rotational position of the rotor blade (15, 15′) is reached and the stand-still position of the rotor blade (15, 15′) reached as a result of the braking procedure is captured. Furthermore, the invention relates to a wind energy plant (10) with a rotor (11) and at least one angle-adjustable rotor blade (15, 15′) arranged on the rotor (11).
