Patent number: 9909562Abstract: A control method for a wind turbine, in particular for a wind turbine blade is described. The control method makes use of the blade mode shapes, or natural vibration shapes, of the blade to detect the excitement level of the blade natural vibrations, and controls active lift devices on the blade in an effort to reduce the excitement levels, to reduce loading in the blade and the overall wind turbine structure. There is also provided a method of designing a wind turbine blade for use in such a method.Type: GrantFiled: December 5, 2012Date of Patent: March 6, 2018Assignee: LM WP PATENT HOLDING A/SInventors: Peter Baek, Christian Frank Andersen, Mark Olaf Slot, Casper Skovby, Simon Berg Bojesen, Morten Ravn, Michael Klitgaard

Patent number: 9617977Abstract: 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.Type: GrantFiled: June 21, 2012Date of Patent: April 11, 2017Assignee: LM WIND POWER A/SInventor: Mark Olaf Slot

Patent number: 9353727Abstract: A method of in situ calibrating load sensors of a horizontal axis wind turbine is described. The method comprises the steps of: a) determining a rotor azimuth angle of a first wind turbine blade, b) determining a pitch angle of the first wind turbine blade, c) measuring loads in a first cross-section of the first wind turbine blade using the first load sensors, d) calculating theoretical loads based on at least the rotor azimuth angle and the pitch angle of the blade determined in steps a) and b), e) comparing the loads measured in step c) with the theoretical loads calculated in step d), and f) calibrating the first load sensors based on the comparison of step e), wherein the calibration are based only on measurements carried out, when the generator is cut out.Type: GrantFiled: January 31, 2011Date of Patent: May 31, 2016Assignee: LM GLASFIBER A/SInventor: Mark Olaf Slot
