Abstract: The invention relates to a method of controlling a wind turbine having a rotor with pitchable wind turbine blades and a generator for producing power, where a control signal for a controllable parameter of the wind turbine is determined, and an operational parameter representing a loading on the wind turbine exerted by the wind is estimated at time intervals. From this is determined a variation parameter reflecting the variation of the operational parameter over time. The wind turbine is then controlled according to the control signal only if the variation parameter is below an alert threshold, and otherwise according to a modified control strategy.

Abstract: A method for controlling operation of a wind turbine and a method for controlling operation of a plurality of wind turbines positioned in a wind farm are disclosed. According to the method, a pitch and rotational speed curve, e.g. a θ versus λ curve, is selected from a group of pitch and rotational speed curve, and the wind turbine is operated in accordance with the selected curve for a short period, while monitoring at least one target parameter, e.g. power production or loads on one or more components. This is repeated for each of the curves of the group of pitch and rotational speed curves. This is also repeated a predetermined number of times, i.e. each curve is selected in turn a predetermined number of times. Based on the monitored target parameters an optimum curve is determined from the group of pitch and rotational speed curve, and the wind turbine is operated in accordance with this optimum curve. The method ensures that the applied curve is in fact optimal for the specific wind turbine, at the specific site and under the specific conditions. Thereby the wind turbine can be operated in a more optimal manner, e.g. with respect to power production and/or loads or wear on components.

Abstract: A method for operating a wind turbine is disclosed. The wind turbine comprises a rotor having a set of wind turbine blades, said rotor being mounted on a tower. The method comprises the steps of: Providing a curve defining optimal pitch angle as a function of tip speed ratio for the wind turbine blades or as a function of wind speed. Modifying at least a part of said optimal pitch angle curve by applying a safety buffer, e.g. at tip speed ratios and/or pitch angles where there is a risk that the blades may stall and/or that overload is caused to the wind turbine, thereby obtaining a safety modified pitch angle curve. Operating the wind turbine in accordance with the safety modified pitch angle curve. Measuring one or more parameters providing information regarding wind conditions and/or loads on one or more components of the wind turbine, during operation of the wind turbine. Adjusting the safety buffer, based on said measurements, thereby obtaining an adjusted pitch angle curve, and operating the wind turbine in accordance with the adjusted pitch angle curve. The safety buffer is applied in order to ensure that the blades of the wind turbine do not stall and/or that the wind turbine is not overloaded, but it has the effect that the wind turbine is operated in a suboptimal manner from an energy production view. Since the safety buffer is adjusted based on measured parameters, it can be reduced if it is detected that the actual operating conditions are less severe than expected. This allows the wind turbine to be operated in a more optimal manner, thereby increasing the energy production of the wind turbine.
