Patent ID: 6946751

Claim:
A wind power generation system comprising: a wind power generator; and a laser aerovane mounted on said wind power generator or located near said wind power generator, said laser aerovane observing direction and velocity of wind blowing toward said wind power generator and controlling at least one yaw angle and pitch angle of said wind power generator based on the direction and the velocity of the wind observed by said laser aerovane, said laser aerovane observing the direction and the velocity of the wind blowing towards said wind power generator by emitting a laser beam ahead of said wind power generator, detecting scattered waves of the laser beam, scattered by an aerosol located at any position distant from said wind power generator, at an arbitrary distance, and that floats in the air and moves on the wind at the same speed as the wind, and detecting a phase difference between the laser beam and the scattered waves in terms of the Doppler effect.
