Method for controlling a wind turbine

摘要

The method involves arranging a nacelle (2) on a tower, and adjusting blade adjustment angle i.e. pitch angle, of a rotor blade (4) with respect to a rotor plane by a blade adjustment equipment. The nacelle is rotated about 90 degrees along a tower axis from an operating position into a rest position when an error of the blade adjustment equipment is detected. Flow of the wind against a virtual surface extended by the rotor blade on rotation of a rotor (3) is reduced with respect to the operating position.
