WIND FARM

A wind farm and a wind power generator capable of improving the power generation amount of the entire wind farm are provided without introducing a central processing unit of the wind farm. A wind farm includes a plurality of wind power generators, the plurality of wind power generators each including a rotor which rotates by receiving at least wind, a yaw angle controller which controls an orientation of a rotational plane of the rotor, and a mode switching device which switches an operation mode of a wind power generator, and a yaw error command value for each wind direction is calculated from a relative position with respect to a wind power generator in a vicinity, and the operation mode of the wind power generator located on a windward side of the plurality of wind power generators is changed, based on the yaw error command value.
