The invention discloses a typhoon-resisting yaw control method for a wind generating set. When a power grid is in a normal condition, if a yaw system of the wind generating set is normal and a wind indicator is normal, the wind generating set initially enters the leeward state; if the yaw system fails or the wind indicator fails, a brake of the yaw system is opened, and the wind generating set is in the free yaw state; and in the situation of outage of the power grid, a UPS and a storage battery supply power, the brake of the yaw system is opened, and the wind generating set is in the free yaw state.
