Abstract:
1. 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, in which the nacelle is rotated around the tower axis, characterised in that the function of the blade adjustment equipment is monitored, and when an error of the blade adjustment equipment occurs, the nacelle ( 2 ) 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, characterised in that the nacelle ( 2 ) is rotated into the rest position only when in addition, the blade adjustment angle of at least one rotor blade ( 4 ) is smaller than a preset limit value of the blade adjustment angle.
