Definitions

  • This horizontal axis wind turbine utilizes a characteristic that an upflow angle or a downflow angle of a wind depends on the lay of the land. Specifically, when a wind direction toward a wind turbine 100 is, in a direction with a certain azimuth angle, one as indicated by an arrow Q in FIG. 5 having an angle of ⁇ to the horizontal plane, a nacelle 102 rotates on each of an inner cam track 104 and an outer cam track 105 so that a rotor shaft 103 a of a rotor 103 turns to point to a certain azimuth angle of the wind direction and stops. At a stop position, a tilt angle, that is a wind-direction angle to the horizontal plane) is set to ⁇ , corresponding to the certain azimuth angle.
  • the inclination angle of the rotor shaft 103 a with respect to the upper surface of a tower head pedestal 101 a in a plane parallel to the horizontal plane comes to be ⁇ .
  • the wind turbine 100 comes to be a state that the rotor 103 faces perpendicularly to the flow of wind in the wind direction. Further, in FIG.
  • the horizontal axis wind turbine described above is so constructed that the nacelle moves to turn by 180 degrees when a wind flow in a direction of a certain azimuth angle changes to a wind flow in the opposite direction, and as to the displacement in a tilt angle direction corresponding to a wind direction in a certain azimuth angle direction, the cam tracks are provided with surfaces formed in advance so that the value of a tilt angle differs according to the azimuth angle.
  • the cam tracks have to be produced having different values of tilt angles correlative to azimuth angles for every installing position, and further a difficulty occurs in work for correcting the angle once set.
  • Patent Document 1 JP-2003-35249A (pages 2-4, and FIGS. 3 and 4).
  • the horizontal axis wind turbine comprises: a nacelle to support the rotor; a tower head which the nacelle is mounted on and comprises a rail with a circular or arc shape thereon; and a roller to support the nacelle, which is movable on and guided by the rail, to control an azimuth direction of the wind turbine.
  • each roller is moved on the rail with a circular or arc shape, in a limited range to correspond to the change of wind direction in the range, which allows the wind turbine to be adjusted within a narrow range for the wind direction in the azimuth-angle direction.
  • the inclination angle can be controlled by extending and retracting the actuators without producing a special cam track which was required by the above-described conventional example, therefore installation cost can be reduced including omission of work to lift a large cam, and further a horizontal axis wind turbine more precisely facing the wind direction can be implemented.
  • the actuator is a hydraulic jack.
  • the wind turbine when the wind turbine is installed at a place where wind directions are changeable, in addition to the above-described changes of the pitch angle and the reverse of rotation, the wind turbine follows the azimuth direction of a wind using the rails and the rollers rotatably moving thereon, and controls the inclination angle by up-and-down control of the actuators to coincide with the wind direction. Accordingly, the wind turbine of the invention has advantages in that installation can be relatively easier and the change after the installation can be also easier.
  • FIG. 3A is a view for illustrating the operation of a horizontal axis wind turbine according to a second embodiment of the invention
  • FIG. 3B is a partially sectional view taken along the line A-A in FIG. 3A ;
  • Such a horizontal axis wind turbine 1 includes a tower 2 placed on the ground, an approximately cylindrical nacelle 4 directly fixed to the tower 2 , a rotor shaft (not shown) rotatably supported to the nacelle 4 , a hub 6 a fixed to the rotor shaft, and a rotor 6 having three blades 6 b 1 - 6 b 3 in the embodiment, each blade attached to the hub 6 a so that its pitch angle is changeable.
  • Each of the blades 6 b 1 - 6 b 3 is attached to the hub 6 a so as to be perpendicular to the rotor shaft.
  • the wind turbine 1 when the wind turbine 1 is placed on the lay of the land like coastline, it is required to control mainly the azimuth angle because wind directions are relatively stable such that a wind blows from the sea to the land in the daytime and from the land to the sea at night, and blows along the ground.
  • the rotor 6 of the wind turbine 1 rotates with a rotating surface facing perpendicular to the flowing direction of the wind, and each of the blades 6 b 1 - 6 b 3 of the rotor 6 is controlled to have a predetermined pitch angle as described above.
  • a horizontal axis wind turbine 20 is a downwind horizontal axis wind turbine similar to the above-described wind turbine 1 . However, the wind turbine 20 can control azimuth angles and tilt angles according to the change of wind direction which is indicated by an arrow in FIG. 3A .
  • the wind turbine 20 is in a state that the rotation plane of the rotor 6 is perpendicular to the flow of the wind direction.
  • the wind direction changes at night to one in a certain azimuth-angle direction, as indicated by an arrow N of the rear side, having an angle of “y” influenced by the lay of the land where the tower 2 is placed (as shown by broken lines)
  • the pitch angle of each of the blades 6 b 1 - 6 b 3 is changed to correspond to the wind direction changed, to reverse the rotating direction of the rotor 6 .
