Abstract
The present invention relates to a method for controlling a wind turbine comprising a pitch of one or more blades and collecting first data indicative of a dynamic condition of the first wind turbine blade and a rotor, the first data comprising rotor data and first deflection data, the rotor data indicative of the azimuth position and rotational velocity of the rotor in a rotor plane perpendicular to the rotor axis, and the first deflection data indicative of the position, speed and acceleration of one or more parts of the first wind turbine blade. The method comprises calculating an expected tower clearance distance at a later time of tower passage for the first blade based on the first data including acceleration of one or more parts of the first blade, and performing measures to prevent tower collision, if the expected tower clearance distance fulfills a collision risk criterion.
