Abstract: The invention relates to a method of controlling a wind turbine comprising one or more blades attached to a rotor hub, the one or more blades being arranged to pitch relative to the hub, the method comprising the steps of obtaining a blade load signal comprising data on an absolute load on the one or more blades; processing the blade load data to detect a high thrust wind event, and generating a control signal comprising a pitch contribution for affecting the blades to pitch out of the wind in response to the detected wind event. The invention also relates to a wind turbine, a control system for a wind turbine and a computer program product being adapted to enable a computer system to perform the method of the invention.

Abstract: The invention relates to a method of controlling a wind turbine comprising blades attached to a rotor hub for rotation in a rotor plane and a control system for individually pitching the blades relative to the hub. The method comprises the steps of dividing the rotor plane into a number of sectors, determining the individual sectors for each blade during the rotation by means of an azimuth angle sensor, and obtaining blade sensor data from a blade sensor on an individual blade relating to a sector,and comparing the obtained data with data relating to the same sector and representing blade sensor data on other blades. Hereby an event may be detected for individual sectors of the rotor plane. When an event is detected in a given sector,an individual pitch contribution t is determined in the sector, and the blades are then pitched according to this individual pitch contribution for that given sector at least partly during passage of the sector. The invention further relates to a wind turbine comprising a control system for individually pitching the blades relative to the hub according to the above mentioned control method. (FIGURE 1)

Abstract: A wind turbine is controlled in response to an estimate of vertical and/or horizontal wind shear. A tilt moment is estimated from flapwise and edgewise blade bending moments, azimuth and blade pitch positions and used to estimate vertical wind shear. A yaw moment is also estimated from flapwise and edgewise blade bending moments, azimuth and pitch position and used to estimate horizontal wind shear. A tip speed ratio is determined from an estimate of wind velocity over the rotor plane and is used to set a blade pitch angle which is passed to a blade pitch controller. The pitching may be collective or individual. In the latter case, the tip speed ratio is determined from a plurality of rotor plane positions to derive a cyclic pitch reference for each blade.
