摘要： 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).

摘要： The invention relates to a method of controlling a wind turbine, the wind turbine comprising wind turbine blades attached to a rotor hub and a control system for pitching the blades relative to the hub. The method comprises providing wake sectors assigned to different wind directions and providing a normal pitch schedule to control an output parameter of the wind turbine (e.g. power, rotational speed), comprising pitch reference values as a function of the wind speed and at least one of the parameters of thrust coefficient C, and axial induction factor a. Further, is provided a modified pitch schedule to control a modified output parameter of the wind turbine, comprising pitch reference values in dependence of the wind speed and at least one modified parameter of the thrust coefficient and/or the axial induction factor. Upon receiving indications of a wind speed and a wind direction at the wind turbine is determined a pitch reference value for the wind turbine blades according to the normal pitch schedule if the wind direction falls outside the wake sector and otherwise according to the modified pitch schedule. The wind turbine is then controlled according to the pitch reference value. The invention further relates to a method of controlling the wind turbines in a wind park, wherein each wind turbine in the park is controlled locally according to the above mentioned control method.

摘要： A method of operating a wind turbine is provided. The wind turbine comprises a turbine rotor with at least two blades, each blade having a variable pitch angle. The method comprises determining mechanical loads on the blades, determining an asymmetric load moment experienced by the turbine rotor based on the mechanical loads on the blades, determining high order harmonics from the asymmetric load moment, and determining an individual pitch control signal for each of the blades for varying the pitch angle of each blade to compensate for the asymmetric load moment. The individual pitch control signal for each blade is determined at least based on the high order harmonics.
