Abstract: Embodiments of the invention generally relate to wind turbine generators, and more specifically to the deactivation of wind turbines in a wind turbine park. A wind park controller may be configured to retrieve data indicating fatigue experienced by each wind turbine of the wind turbine park, and deactivate those turbines determined to be the most fatigued, thereby increasing the lifetime of turbines in the wind turbine park.

Abstract: To efficiently nm a wind turbine in varying wind speeds, the wind turbine may be configured to switch between two different electrical configurations that offer different efficiencies depending on wind speed. For example, a star configuration may be preferred during low wind speeds while a delta configuration is preferred for high wind speeds. Before switching, the power output by the turbine's generator may be driven to zero. Doing so, however, removes load from the rotor blades which cause the rotor speed to increase. Instead, the rotor speed may be controlled such that the speed stays at or above the speed of the rotor immediately before the generator power is ramped down. Maintaining rotor speed at or slightly above the current speed while switching between electrical configurations may mitigate the torque change experienced by the turbine and reduce the likelihood of structural failure.

Abstract: Embodiments of the present invention relate to control of a wind turbine during a recovery period after a grid fault. It is disclosed to operate a wind turbine during the recovery period to determine the actual pitch angle of the rotor blades and the actual wind speed, and based on that determining a desired pitch angle of the rotor blades, as well as a pitch ramp rate so that the actual pitch angle can be brought to match the desired pitch angle before the end of the recovery period. In embodiments, the steps performed in the recovery mode are repeated at intervals during the recovery period.

Abstract: The present invention relates to a method for operating a wind power plant in a wake situation, said wind power plant being connected to a power grid, the method comprising the steps of operating the wind power plant in a predetermined power mode of operation, terminating said predetermined power mode of operation, and increasing power generation of the wind power plant to a power level that exceeds an optimized wake power level of the wind power plant, and injecting the increased amount of power into the power grid as a power boost. Thus, the present invention is capable of generating a power boost to an associated power grid, said power boost exceeding the power level normally being available in a wake situation.

Abstract: 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.

Abstract translation: 为了有效地在不同的风速下对风力涡轮机进行nm，风力涡轮机可以被配置为在根据风速提供不同效率的两种不同的电气配置之间切换。 例如，在低风速期间，星形结构可能是优选的，而对于高风速而言，优选配置delta配置。 在切换之前，涡轮发电机输出的功率可能被驱动到零。 然而，这样做可以消除转子叶片的负载，导致转子转速增加。 相反，可以控制转子速度，使得在发电机功率下降之前，转速保持等于或高于转子的速度。 在转换电气配置之前，将转子速度保持在或略高于当前速度可以减轻涡轮机所经历的扭矩变化，并降低结构故障的可能性。

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).
