Abstract: This invention relates to a method and a power plant controller arranged to carry out the method. The method is on an intelligent dispatching of the power production to wind turbines and optional compensation equipment of a wind power plant, as the power producing units of a wind power plant. The invention relates to a case where the requested produced power (both active and reactive) is less than the total capacity of the power plant, and the invention relates to utilizing this situation to dispatch set points to the wind turbines and the compensation equipment based on correction factors relating to the operating conditions of the wind park. This method may increase the wind turbines' life time, help in scheduling maintenance and expand the electrical operating range of the wind power plant.

Abstract: Methods, controllers and computer program products for controlling a wind turbine. Under de-rated operating conditions in which the power requested from a wind turbine is less than the available power, a controller adjusts blade pitch of the wind turbine to reduce the rotor power coefficient. The captured wind power is thereby reduced to be approximately equal to the requested electrical power, which is less than either the available power or the rated power of the wind turbine generator. This reduction in captured power provides the controller with an additional degree of freedom that allows the controller to increase the electrical power output of the wind turbine in response to wind fluctuations without damaging the wind turbine. By allowing increases in power under de-rated conditions, the controller may reduce the amount of pitching necessary to prevent the turbine from exceeding its rated power output level.

Abstract: This invention relates to a method and a power plant controller arranged to carry out the method. The method is on an intelligent dispatching of the power production to wind turbines and optional compensation equipment of a wind power plant, as the power producing units of a wind power plant. The invention relates to a case where the requested produced power is less than the total capacity of the power plant, and the invention relates to utilizing this situation to dispatch set points to the wind turbines and the compensation equipment in a flexible way. This flexibility may increase the wind turbines' life time, help in scheduling maintenance and expand the electrical operating range of the wind power plant. The determination of the set points on active and reactive power is a combined determination of both set points for each of the energy producing units of the wind power plant.

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: According to an aspect of the invention, a wind farm is provided. The wind farm includes a plurality of wind turbines and a wind farm controller. The controller is configured to detect a high wind condition from at least one wind turbine in the wind farm, reduce a parameter setpoint of at least one other wind turbine, and increase a cut-out wind speed threshold of the at least one other wind turbine.

Abstract: The disclosure is provides for warning a wind turbine generator (WTG) in a wind park of an extreme wind event. According to one embodiment, one or more front line WTGs of the wind park that detect extreme wind events and provide the warning are adaptively selected based on a measured wind direction. Thus, the selection of front line WTGs is adaptive to changing wind conditions. In another embodiment, a wind park includes a group of one or more WTGs of a first type located in an inner region of the wind park and a plurality of WTGs of a second type located in an outer region of the wind park that at least partially surrounds the inner region. The first type of WTG is structurally weaker and/or rated for higher performance than the second type of WTG.

Abstract: Embodiments of the invention are generally related to optimizing performance of a wind power plant. A controller may be configured to determine that a first wind turbine is in the wake of a second wind turbine and that power production at the first wind turbine can be increased by reducing power production at the second wind turbine. The controller may be further configured to cause the second wind turbine to reduce power production.

Abstract: Embodiments of the invention are generally related to optimizing performance of a wind power plant. A controller may be configured to sequentially, for each wind turbine in a wind power plant, adjust the power production by a predefined amount, and determine whether the adjustment of power production from the wind turbine results in an increase in overall power production from the wind farm. Adjustments in power production of the wind turbines may be continuously made so that power production of the wind power plant approaches the maximum possible value.
