Abstract: The present invention refers to a method for operating a wind turbine, the wind turbine particularly comprising a tower and a rotor with rotor blades. The pitch angles of the rotor blades are adjusted to generate a force on the rotor and the tower. The force is adjusted to counteract and damp an oscillation. The adjustment is enabled by an activation decision unit, if the activation decision unit decides that certain parameters characterising the oscillation or loads of the tower indicate a requirement and/or if the activation decision unit determines that the generated force is sufficient to counteract an oscillation of the tower. In various embodiments the parameters characterising the oscillation or loads of the tower comprise current oscillations and their amplitude, an estimate of loads incurred in the turbine structure, an estimate whether damping in the near future might become necessary, an indication whether a different oscillation damping algorithm than individual blade pitch control is currently performing, and an indication whether a wind speed is above a certain portion of a rated wind speed.

Abstract: A method for controlling a wind energy farm is disclosed. A wake state of the wind energy farm is determined, including determining wake chains defining wake relationships among the wind turbines (1) of the wind farm under the current wind conditions. For at least one of the wind turbines (1) of the wind energy farm, a lifetime usage is estimated, based on an accumulated load measure for the wind turbine (1). In the case that the estimated lifetime usage is below a predefined lifetime usage limit, the wind turbine (1) is operated in an overrated state, while monitoring wake effects at each of the wind turbines (1). In the case that a downstream wind turbine (1) detects wake effects above a predefined wake threshold level, at least one wind turbine (1) having an upstream wake relationship with the downstream wind turbine (1) is requested to decrease the generated wake, e.g. by decreasing power production.

Abstract: A method of controlling pitch of individual blades in a wind turbine is described, together with a suitable controller. Wind speed is determined as a function of azimuthal angle (412). Wind speed (421) is then predicted for individual blades over a prediction horizon using this determination of wind speed as a function of azimuthal angle. The predicted wind speed for each individual blade is used in a performance function, which is optimised to control individual blade pitches (431).

Abstract: A wind turbine control system comprising a controller of a control mechanism of a wind turbine, wherein the controller implements a computerised real-time blade model to calculate operational parameters of the controller, and wherein the computerised real-time blade model receives as inputs a determined wind turbine operating point and a rotor-plane wind speed value that is estimated in real-time. In another aspect, the embodiments of the invention provide a method of controlling a control mechanism of a wind turbine. Advantageously, the invention provides a more flexible and responsive control system that is able to adapt to changing wind conditions even if those wind conditions are beyond what is usually predicted.
