Abstract: There is provided a yaw control technique for a wind turbine generator that can decrease the magnitude of the wind direction deviation even though the wind direction changes gradually over an extended period of time while suppressing an increase in the number of yaw rotations. Further, there is provided a yaw control technique for a wind turbine generator that can improve the efficiency of a wind turbine generator by performing yaw rotation at an appropriate timing through early detection of transitional changes in the wind direction. The wind turbine generator includes a nacelle in which a wind turbine rotor is mounted, a rotating mechanism that performs yaw rotation of the nacelle, a wind direction measuring means that measures a wind direction, and a controller that controls the rotating mechanism.

Abstract: A moving turbine blade is disclosed. When an angle, which a tangent to a dorsal surface portion at a front edge of the moving turbine blade makes with a straight line perpendicular to a rotating shaft of a turbine, is designated as &thgr;, and a geometrical outlet angle of a stationary blade is designated as &agr;n, &thgr; is in the relationship &agr;N+2°<&thgr;<&agr;N+12°. As a result, the shape of the dorsal surface portion, at the front edge and in a portion adjacent thereto, of the moving turbine blade is not parallel to a stationary blade wake. Thus, the moving turbine blade can contribute to increasing the efficiency of the turbine, while suppressing an unsteady sharp increase in flow velocity.
