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.
