METHOD FOR DRIVING YAW OF WIND POWER GENERATOR WITHOUT CABLE TWIST

摘要

Disclosed is a method for driving the yaw of a wind power generator without twisting a cable. The method for driving the yaw of a wind power generator according to an embodiment of the present invention comprises a step of measuring wind angles (a); a step of determining the direction of the minimum angle for rotating a nacelle by comparing the wind angles with the angle of the nacelle (b); a step of comparing a twisting angle with the twisting limit angle when the nacelle rotates in the direction of the minimum angle (c); and a step of rotating the nacelle in the opposite direction to the direction of the minimum angle when the twisting angle is greater than the twisting limit angle or in the direction of the minimum angle when the twisting angle is not greater than the twisting limit angle. [Reference numerals] (AA) Yes; (BB) No; (S200) Determining the direction of the minimum angle according to wind angles currently measured; (S210) Twisting angle in rotation > Twisting limit angle; (S220) Rotating a nacelle in the opposite direction to the direction of the minimum angle; (S230) Rotating the nacelle in the direction of the minimum angle
