Wind power generation unit, wind farm, and arrangement structure and control method of the same

摘要

A wind farm includes a plurality of wind power generation units each including a rotation axis, a hub, at least two airfoil blades, a pitch control system and a yaw control system. At least two first-direction wind power generation units are spaced apart longitudinally from each other along a prevailing energy wind direction at a predetermined interval and whose blades are rotated in a same direction. At least one second-direction wind power generation unit that is located between the first-direction wind power generation units and has blades rotating in an opposite direction to a rotational direction of the blades of the first-direction wind power generation units.

1. A wind farm, comprising
a plurality of wind power generation units, each wind power generation unit including:
a rotation axis;a hub located at a first end portion of the rotation axis;at least two airfoil blades radially mounted on the hub;a pitch control system configured to adjust a pitch angle of the blades mounted on the hub; anda yaw control system configured to horizontally rotate the rotation axis to adjust a direction of the rotation axis with respect to a prevailing energy wind direction, wherein at least two first-direction wind power generation units are spaced apart longitudinally from each other along the prevailing energy wind direction at a predetermined interval and whose blades are rotated in a same direction, and at least one second-direction wind power generation unit is located between the first-direction wind power generation units and has blades rotating in an opposite direction to a rotational direction of the blades of the first-direction wind power generation units.
