Abstract
A control device is provided which is adapted for controlling at least one operational parameter of a wind turbine including a machine nacelle and a rotor having at least one rotor blade. The control device includes an input adapted for inputting a signal which is indicative of environmental data of the wind turbine, an evaluation unit adapted for generating at least one control signal on the basis of currently acquired environmental data and on the basis of previously acquired environmental data, and an output adapted to output the control signal adapted for adjusting the at least one operational parameter of the wind turbine.

A control device adapted for controlling at least one operational parameter of a wind turbine comprising a machine nacelle and a rotor having at least one rotor blade, said control device comprising:
- an input adapted for inputting a signal which is indicative of environmental data of the wind turbine;
- an evaluation unit adapted for generating at least one control signal on the basis of currently acquired environmental data and on the basis of previously acquired environmental data;
- and
- an output adapted to output the control signal adapted for adjusting the at least one operational parameter of the wind turbine.
A wind turbine comprising a machine nacelle and a rotor having at least one rotor blade, said wind turbine further comprising:
- a wind sensor unit adapted for measuring a direction and a velocity of incoming wind as wind data at at least one radial position of the at least one rotor blade;
- a rotation sensor adapted for detecting a rotational position of the rotor of the wind turbine;
- a pitch angle adjustment unit adapted for adjusting a pitch angle of at least one rotor blade;
- and
- a control device comprising an evaluation unit adapted for generating at least one control signal on the basis of currently acquired wind data and on the basis of previously acquired wind data,
- wherein the control signal is adapted for adjusting the pitch angle of at least one rotor blade.
A method for controlling at least one operational parameter of a wind turbine comprising a machine nacelle and a rotor having at least one rotor blade, said method comprising:
- measuring of actual environmental data at the location of the wind turbine;
- storing the measured environmental data;
- generating at least one control signal on the basis of currently acquired environmental data and on the basis of previously acquired environmental data;
- and
- adjusting the at least one operational parameter of the wind turbine on the basis of the control signal.
