Definitions

  • the direction may be a direction calculated based on the surrounding wind condition distribution.
  • the rotor shaft angle ⁇ r may be a direction facing the rotor rotation axis, a nacelle direction, a value measured by an encoder of the yaw turning unit, or the like.
  • FIG. 3 is a block diagram showing functions of a yaw control unit included in the control device shown in FIG.
  • the yaw control unit 300 includes a yaw deviation angle calculation unit 301 for calculating a yaw deviation angle ⁇ , a yaw rotation stop threshold calculation unit 310 for calculating a yaw rotation stop threshold ⁇ y, a yaw deviation angle ⁇ , and a yaw deviation angle ⁇ .
  • the yaw deviation angle calculation unit 301 determines the yaw deviation angle ⁇ based on the rotor shaft angle ⁇ r and the wind direction ⁇ w. As shown in FIG. 2, the yaw deviation angle ⁇ is a difference between the wind direction ⁇ w and the rotor shaft angle ⁇ r, and indicates how much the rotor shaft deviates from the wind direction.
  • the wind direction ⁇ w is not limited to the value detected from the wind direction / wind speed sensor 10 installed in the nacelle 5, and may be a value installed on the ground or another place.
