<p>The invention concerns a method for reducing mechanical oscillation in a wind power plant 1 which comprises a plurality of rotor blades 2, a wind turbine drive train 3 and a generator 4, wherein the rotor blades 2 are rotatably connected to the generator 4 by the wind turbine drive train 3. The method comprises the steps: mathematically modeling the dynamical response and/or transfer function of a group of rotatable parts of the wind power plant, the group of rotatable parts comprising at least the wind turbine drive train 3, and determining dynamical response and/or transfer function of the group; in operation of the wind power plant 1, determining a first parameter characteristic of the mechanical oscillation at a first location, controlling the operation of at least one rotatable part in response to the dynamical response and/or transfer function of the group and at least the first parameter. In effect, resonance induced mechanical wear is reduced which leads to an increased life time of the wind power plant 1.</p> |
