Method and control system for reducing vibrations of a wind turbine

摘要

A method and a control system for reducing vibrations of a wind turbine (100) having a plurality of set points characterizing the set values of operation parameters of the wind turbine (100) is provided, wherein the method comprises 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 modifying the set point value of at least one set point of the plurality of set points to reduce the vibrations (350) in such a way that a power output of the wind turbine (100) is not reduced.
