    摘要: A method for reducing vibrations of a wind turbine includes a plurality of set points characterizing set values of operation parameters of the wind turbine. The method includes measuring an acceleration force value corresponding to acceleration forces acting on the turbine, and determining whether the measured acceleration force value is above a predetermined threshold value. Furthermore, in case it is determined that the acceleration force value is above the predetermined threshold value, the set point value of at least one set point of the plurality of set points is modified in order to reduce the vibrations in such a way that a power output of the wind turbine is not reduced.

    摘要: A method for acoustically monitoring a wind turbine, in particular for monitoring the existence of loose objects inside the wind turbine is provided. A sound generated in a rotating part of the wind turbine is monitored during operation of the wind turbine which sound is analyzed with respect to specific parameter values of the sound within at least one specific frequency range and if such specific parameter values are detected, a signal for possible further actions is generated. An acoustic monitoring system for a wind turbine and a re-equipment kit are also disclosed.

    摘要: A method of de-icing wind turbines of a wind park is provided. At least a first wind turbine and a second wind turbine are assigned to the wind park. The first wind turbine produces a first electrical output power, which exceeds a first power threshold value. The second wind turbine produces a second electrical output power, which falls below a second power threshold value. The first output power and the second output power are reported to a power controller of the wind park. The power controller detects that the first electrical output power exceeds the first power threshold value and the power controller detects that the second electrical output power falls below the second power threshold value. The power controller initiates a de-icing procedure being executed at the second wind turbine until the second electrical output power exceeds the first threshold value.
