    Abstract: A method is provided for warning a wind turbine generator (WTG) (100) in a wind park (200, 400, 1300) of an extreme wind event. According to one embodiment of the method, one or more WTGs are adaptively selected to operate as front line WTGs. The one or more front line WTGs detect extreme wind events and provide a warning (230) to other WTGs. The selection of front line WTGs is adaptive to changing wind conditions. In another embodiment, a wind park (200, 400, 1300) includes a group of one or more WTGs of a first type (220) located in an inner region of the wind park and a plurality of WTGs of a second type (210) located in an outer region of the wind park that at least partially surrounds the inner region. The first type of WTG (220) is structurally weaker and/or rated for higher performance than the second type of WTG (210).

    Abstract: The present invention relates to a method for curtailing electrical power supplied from a wind turbine or a group of wind turbines to an associated power supply grid, the method comprising the steps of determining an available electrical power level from the wind turbine facility and setting a wind speed independent curtailment level. The curtailment level may be a percentage of an actual available electrical power level or a fixed power level. The method further comprises the step of operating the wind turbine facility in such a way that the generated electrical power supplied from the wind turbine facility equals the difference between an actual available electrical power level and the curtailment level. The present invention further relates to a wind turbine facility and a curtailing controller for carrying out the invention.

    Abstract: 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.
