摘要： A wind turbine controller for controlling power production of a wind turbine is provided. The wind turbine is arranged within a wind farm coupled to a public power network via a point of common coupling. The wind turbine controller has a receiving unit for receiving a measured value of a property of the wind farm taken at the point of common coupling and for receiving a reference value for the property, and a control unit for controlling the power production of the wind turbine by regulating a local property of the wind turbine based on the received measured value and the received reference value such that the measured value of the wind farm taken at the point of common coupling corresponds to the reference value. Further, a wind turbine having such a controller, a wind farm and a method for controlling a power production of a wind turbine are provided.

摘要： The present invention relates to a control system for thrust-limiting of wind turbines, which wind turbine comprises at least one tower, which tower carries at least one nacelle which nacelle comprises a rotating shaft, which shaft is rotated by one or more blades, which blades at pitch regulated by a pitch control system. It is the object of the present invention to reduce mechanical load and stress of a wind turbine. A further object is to reduce the maximal load on tower of a wind turbine. The thrust-limiting control system performs control of the pitch angle, which thrust-limiting control system performs regulation of the pitch angle based on at least a first input from a wind estimator and a second input from a turbulence estimator. By thrust-limiting control, reduction in the maximum mechanical load on a tower, or maybe also a nacelle, can be achieved by a relatively high percentage of the load in a way where it has only very limited influence on the power production of the wind turbine.
