摘要： Embodiments of the invention generally relate to wind turbine generators, and more specifically to improving power production in wind turbine generators. A rotor plane of the wind turbine may be divided into a plurality of sections. A characteristic of wind associated with each section may be determined. An optimal pitch angle may be determined for each section based on the associated wind characteristic. A pitch controller may adjust the pitch angle of a blade to the optimal pitch angle as the blade sweeps through the section.

摘要： 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 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. When an event is detected in a given sector, an individual pitch contribution 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.

摘要： Blades of a wind turbine attached to a rotor hub for rotation in a rotor plane may be adjusted by a control system for individually pitching the blades relative to the hub. The rotor planes divided into a plurality of predefined section, wherein each section has an associated pitch reference value. A light detection and ranging device may be used to determine expected properties of wind in each respective section of the rotor plane so that the pitch reference value may be adjusted accordingly.
