Abstract
The invention regards an apparatus for adjusting the yaw of a wind turbine adapted for mounting on a wind turbine comprising, a system for measuring the wind direction adapted, via a control signal, to control the yaw angle of the wind turbine based on the wind direction, and a wind sensor system adapted to determine the yaw error of the wind turbine, and means for modifying the control signal based on the yaw error determined by the wind sensor system.
Claims18
An apparatus for adjusting the yaw of a wind turbine adapted for mounting on a wind turbine comprising,
- a system for measuring the wind direction operative, via a control signal, to control the yaw angle of the wind turbine based on the wind direction, and
- a wind sensor system operative to determine the yaw error of the wind turbine, and
- means for modifying the control signal based on the yaw error determined by the wind sensor system.
A wind turbine comprising an apparatus according to any of the preceding claims.
A method for adjusting the yaw angle of a wind turbine wherein a wind measuring device controls the yaw of the wind turbine and, wherein the controlled yaw angle is modified on the basis of a yaw error determined by a wind sensor system.
