摘要： The invention relates to a wind turbine, a method of controlling loads in a wind turbine blade thereof, and a method of monitoring buckling in a wind turbine blade thereof. The wind turbine blade comprises predetermined means arranged in the first and second shell parts, wherein these means are configured to initiate buckling at extreme load conditions. This provides a simple and lightweight wind turbine blade capable of retaining its original aerodynamic shape without significant structural damages. These means may also be used for passive load control, wherein the means are activated in a maximum compression load situation and decreases the aerodynamic efficiency and, thus, reduces the compression loads. These means may further be used for monitoring the buckling using suitable sensors or measuring units, wherein a control unit analyses and evaluates the signals from these sensors or measuring units and then determine a buckling signal indicative of the actual buckling.

摘要： The present invention relates to a method of increasing the output of a wind turbine, wherein one or more flow surfaces are placed at a wind turbine. At lower wind speeds, the flow surfaces are set to guide the wind up towards and/or out from the rotor of the wind turbine and hence use the venturi effect in the rotor to advantage. At higher wind speeds, the flow surfaces are completely or partially taken out of the flow of the wind. Moreover, the flow surfaces can be adjusted around the wind turbine based on measurements of the speed of the wind and direction of the wind and/or the power signal of the wind turbine. The invention further relates to a system comprising one or more flow surfaces and means for adjusting same to the effect that the output of a wind turbine can be maximised by using the venturi effect to advantage as described above.

摘要： A wind turbine has a generator (7) with a connected rotor (3) having a hub (4) and blades (5) rotatably connected to the hub for adjusting the pitch angle. In a method of operating such a wind turbine under climatic conditions, where there is a risk of icing on the blades and no or weak wind, the generator is used as a motor for driving the rotor and the pitch angle of the blades is adjusted to ensure that the resulting wind substantially hits the leading edge of the blades. Any ice formed may be removed by means of de-icing in a known manner.
