Rotational speed control of a wind turbine based on rotor acceleration |
摘要 |
It is described a method for controlling the rotational speed of a rotor (110) of a wind turbine (100) in particular at high wind speeds. The described method comprises (a) determining a rotor acceleration value, wherein the rotor acceleration value is caused by a temporal change of the rotational speed of the rotor (110), and (b) controlling the rotational speed of the rotor (110) as a function of the rotor acceleration value. It is further described a control system (150, 250) for controlling the rotational speed of a rotor (110) of a wind turbine (100), a wind turbine (100) being equipped with such a control system (150, 250) and to a computer program, which is adapted for controlling and/or for carrying out the mentioned rotational speed control method. |
