Abstract

The present invention is related to a method for controlling a wind energy plant, with a nacelle disposed on a tower and with a rotor with at least one rotor blade, the blade adjustment angle of which can be adjusted by means of a blade adjustment equipment. The objective to provide a reduction of the loads acting on the plant when there is a malfunction of the blade adjustment equipment is resolved according to the present invention in that the function of the blade adjustment equipment is monitored, and when an error of the blade adjustment equipment occurs, the nacelle is rotated from an operating position into a rest position, in which there is a flow of the wind against the surface extended by the at least one rotor blade (4) in a rotation of the rotor which is reduced with respect to the operating position.
