METHOD AND ARRANGEMENT FOR CONTROLLING A WIND TURBINE |
摘要 |
A method of controlling a wind turbine having a rotor to which at least one rotor blade is connected, is provided herein. The method includes operating the rotor according to a first rotational speed reference; and operating the rotor according to a second rotational speed reference above the first rotational speed reference, if a fluctuation of an actual rotational speed of the rotor decreases below a fluctuation threshold and/or if a blade pitch angle of the rotor blade increases above a blade pitch angle threshold. The method may further include wherein the rotor is operated according to the first rotational speed reference, if the fluctuation of an actual rotational speed of the rotor increases above another fluctuation threshold which is above the fluctuation threshold and/or if the blade pitch angle of the rotor blade decreases below another blade pitch angle threshold which is below the blade pitch angle threshold. |
