Abstract: A method of controlling a floating-body wind turbine power generating apparatus including a wind turbine generator disposed on a floating body includes a pitch-angle increasing step of increasing a pitch angle of a blade of the wind turbine generator when the wind turbine generator is stopped, so that an aerodynamic braking force is applied to a rotor of the wind turbine generator. In the pitch-angle increasing step, a first change rate of the pitch angle of the blade in a first period during which the wind turbine generator is in an inclining motion toward an upwind side from a vertical direction due to sway of the floating body, is smaller than a second change rate of the pitch angle of the blade in a second period during which the wind turbine generator is in an inclining motion toward a downwind side from the vertical direction due to the sway of the floating body.

Abstract translation: 一种控制浮体风力发电装置的方法，包括设置在浮体上的风力涡轮发电机，其包括在风力发电机停止时增大风力发电机叶片的俯仰角的俯仰角增大步骤 ，使得空气动力学制动力施加到风力涡轮发电机的转子。 在俯仰角增加步骤中，叶片在俯仰角度的第一期间中的俯仰角的第一变化率，在该第一期间，由于浮体的摆动，风力发电机从垂直方向向上风侧倾斜运动， 小于叶片俯仰角的第二变化率，在第二时段期间，由于浮体的摆动，风力涡轮发电机从垂直方向向下风向侧倾斜运动。
