CORRECTION APPARATUS FOR YAW ALIGNMENT ERROR OF WIND TURBINE

摘要

The present invention relates to an apparatus for correcting a yaw alignment error of a wind power generator. The apparatus comprises: a first detection unit which is installed in a nacelle for a wind power generator and senses a first measurement variable; an axial direction detection unit which detects the direction of a current yaw axis of the nacelle; a control unit which calculates an alignment error angle based on the detected value of the first detection unit; and a driving unit which rotates the nacelle by the alignment error angle. Therefore, the present invention can minimize a yaw error by realizing an alignment error which is the same as or close to a precise measurement device, thereby maximizing the efficiency of power generation.
