Horizontal axis wind-driven generator with continuously adjustable wind wheel rotating angle and adjusting method thereof

The invention discloses a horizontal axis wind-driven generator with a continuously adjustable wind wheel rotating angle and an adjusting method thereof. The horizontal axis wind-driven generator comprises a primary yawing motor, a primary yawing planetary gear, a secondary yawing motor and a secondary yawing planetary gear, wherein the primary yawing motor and the primary yawing planetary gear form a drive yawing gear mechanism which performs coarse adjustment according to a yaw command sent by a control circuit; and the secondary yawing motor and the secondary yawing planetary gear form a driven yawing gear mechanism which performs secondary fine adjustment on the basis of the primary adjustment, so that continuous change and adjustment of a rotating angle of the horizontal axis wind-driven generator is realized. Therefore, the device can be adjusted by continuously changing the rotating angle in a yawing state; and the utilization efficiency of wind energy is improved.
