Abstract
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.
