Abstract
A method of controlling the yawing of two-bladed wind turbine is described. The yaw speed of the turbine is increased when the wind turbine rotor blades are in a substantially vertical position, and the yaw speed may be reduced when the blades are substantially horizontal. By modulating the yaw rate based on the rotational angle of the blades, the effect of the yaw moments on the wind turbine structure is reduced, and the wind turbine may be designed to take into account such reduced forces.
