Controlling offshore wind turbines with respect to damping effects

A method of controlling a plurality of offshore wind turbines with respect to a mechanical oscillation damping effect is described, the method comprising: obtaining wave characteristic information (3) indicative of a characteristic of at least one sea wave; obtaining wind turbine operating state information (5) of the plurality of wind turbines; obtaining wind characteristic information (7); the wind turbines are controlled with respect to a damping effect on the basis of the wave characteristic information (3) and/or the wind turbine operating state information (5) and/or the wind characteristic information (7) of the plurality of wind turbines, in particular such that power oscillations of the total power output of the wind farm are reduced. 描述一种关于机械振荡阻尼作用控制多个海上风力涡轮机的方法，所述方法包括：获得指示至少一个海浪的特性的波浪特性信息(3)；获得所述多个风力涡轮机的风力涡轮机操作状态信息(5)；获得风特性信息(7)；基于所述波浪特性信息(3)和/或所述多个风力涡轮机的所述风力涡轮机操作状态信息(5)和/或所述风特性信息(7)关于阻尼作用控制所述风力涡轮机，特别是使得所述风电场的总功率输出的功率振荡减小。
