| 发明名称 | Method of controlling a wind turbine and related system | ||
| 摘要 | 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. | ||

| 主权项 | 1. A method of controlling a wind turbine comprising a tower and a rotor provided on top of the tower, the rotor comprising one or more wind turbine blades including at least a first wind turbine blade that rotates about a rotor axis, the method comprising the steps of: collecting first data indicative of a dynamic condition of the first wind turbine blade and the rotor, the first data comprising rotor data and first deflection data, the rotor data being 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 being indicative of the position, speed and acceleration of one or more parts of the first wind turbine blade, and calculating an expected tower clearance distance at a predicted time of tower passage for the first wind turbine blade based on at least the acceleration of said one or more parts of the first wind turbine blade in a direction perpendicular to the rotor plane and further on a stiffness or natural frequency of the first wind turbine blade, and performing measures to prevent tower collision, if the expected tower clearance distance fulfills a collision risk criterion. | ||
