    • PROBLEM TO BE SOLVED: To effectively suppress yaw movement of a nacelle by making the resistant torque to the yaw movement of the nacelle act according to a rate of change of the azimuth angle of the nacelle without adding a special equipment for acting the resistant torque to the yaw movement of the nacelle to the basic constitution of a horizontal axis wind turbine.SOLUTION: A control apparatus C of a horizontal axis wind turbine apparatus WTG calculates the value en of a pitch angle command for each blade based on the rate of change ΨD of the azimuth angle Ψ of a Nacelle N and the rotor azimuth angle φ; of the blades B1, B2 and B3, causes the rotor to generate torque around the yaw axis by periodically controlling the angle change of the pitch angle of the blades, and using that torque, controls the rate of change of the azimuth angle of the nacelle. The value of that angle change is calculated as a value that increases as the input value of the rate of change ΨD increases.
    • 要解决的问题:为了有效地抑制机舱的偏航运动,通过使机舱的偏航运动的阻力转矩根据机舱的方位角的变化率而起作用,而不增加用于作用的特殊设备 对机舱的偏航运动的抵抗力矩相对于水平轴风力涡轮机的基本构造。 解决方案:水平轴风力涡轮机设备WTG的控制装置C基于机舱N的方位角Ψ的变化率ΨD和转子方位角度来计算每个叶片的俯仰角度指令值en φ; 通过周期性地控制叶片的俯仰角的角度变化,使得转子绕偏转轴产生转矩,并且使用该转矩来控制机舱的方位角的变化率 。 该角度变化的值被计算为随着变化率ΨD的输入值增加而增加的值。 版权所有(C)2012,JPO&INPIT
