Abstract: A wind turbine includes a tower, an aerodynamic rotor operable at a variable rotor speed and having a plurality of rotor blades each having an adjustable rotor blade setting angle and a generator for generating an electrical output power. An operating characteristic curve is prespecified for operating the wind turbine. The operating characteristic curve indicates a relationship between the rotor speed and the output power. A controller is provided, which sets the output power in accordance with the operating characteristic curve depending on the rotor speed. The the operating characteristic curve has a starting rotation speed to which the rotor speed increases as soon as the wind turbine starts when a sufficient wind speed is reached. The starting rotation speed is defined depending on a tower natural frequency of the wind turbine and/or depending on a detected turbulence measure of the prevailing wind.

Abstract: A two-part or multi-part rotor blade and also to a method which is associated with it. The rotor blade is split into at least one rotor blade component which is close to the hub and one rotor blade component which is remote from the hub at a separation point in the longitudinal direction, wherein the rotor blade component which is close to the hub and the rotor blade component which is remote from the hub can be connected at the separation point for operation of the wind turbine. A ratio of profile thickness to profile depth, called relative thickness, at the separation point lies within a range of from 0.4 to 0.5. An improved two-part or multi-part rotor blade in spite of the unexpectedly high relative thicknesses.

Abstract: A method of controlling a wind power plant for generating electrical power from wind is provided. The plant comprises a rotor having rotor blades with adjustable blade angles and the rotor can be operated at a variable rotational speed. The method includes controlling the plant in a partial load mode when wind speed is below a nominal speed and, controlling the plant in a storm mode when the wind speed is above a storm commencement speed. An output power of the plant in the partial load mode and storm mode is adjusted according to an operating characteristic curve that determines a relationship between the rotational speed and the output power. A partial load characteristic curve is used as the operating characteristic curve for controlling the power plant in partial load mode, and a storm mode characteristic curve is used as the operating characteristic curve for controlling the plant in storm mode.
