    摘要: A method for controlling an active power output in a wind farm comprises inputting a setpoint of the active power into a ramp and limiting unit to determine an internal active power setpoint. Inputting the internal active power setpoint into a distributing unit configured to calculate a modeled active power setpoint of the wind farm. Determine by a subtraction element, a control difference that is a difference between the modeled active power setpoint and an actual value of the active power output of the wind farm. Determine a controller setpoint variable and calculating an overall setpoint variable from the controller setpoint variable and the feed-forward control variable. Splitting the overall setpoint variable for models of the wind turbines and determining using the wind turbine models the modeled active power setpoint of respective wind turbines depending on a portion of the active power setpoint.

    摘要: A wind turbine rotor blade has a longitudinal axis, a blade root, a blade tip, a pressure side, a suction side and an aerodynamic profile which, in a longitudinal section of the rotor blade, has a profile chord and a thick trailing edge. The rotor blade includes a multiplicity of flow deflection elements which are arranged on the thick trailing edge and have respective inflow surfaces which are shaped and arranged such that a radial flow running in the direction from the blade root toward the blade tip is diverted by the inflow surface in the direction of the profile chord.

    摘要: A method for making a wind turbine member wherein a plurality Of components are arranged in a mold. The inner side of the mold determines a surface of the wind turbine member. The components are connected to one another. At least one of the components is a prefabricated structural element which has a fixed geometry with an outer surface. The prefabricated structural element has a positioning projection protruding out of the outer surface and the mold has, on its inner side, a positioning receptacle. The positioning projection is inserted positively into the positioning receptacle to determine the disposition of the prefabricated structural element in the mold.
