Abstract
A wind turbine includes a laser wind velocity measurement system mounted on a nacelle of the wind turbine for determination of air velocities at the same relative position in front of the wind turbine, and which compensates for wind velocity changes prior to impingement of the air flow on the adjustable pitch wind turbine blades so that desired maximum tip speeds, tip speed ratios, and normalized power output C,may be maintained.
