The invention discloses an offshore wind driven generator set and a mounting method thereof. The offshore wind driven generator set comprises a semi-submersible type floating body, a ship type platform, a tower, a cabin, impellers, vertical tail wings, an inclined supporting rod and the like, wherein the semi-submersible type floating body comprises a front floating barrel and at least one rear floating barrel; the upper part of the front floating barrel is conical, is inserted into a yaw tapered rotary bearing, and an anchoring system is connected to the middle lower part of the front floating barrel; a truss structure is arranged above a water level of each rear floating barrel, a dowel pin is arranged at the top of each rear floating barrel and is rigidly connected with a positioning device; a pressure equalizing tube is connected with each rear floating barrel. The ship type platform adopts a gabbart mode, the yaw tapered rotary bearing is arranged on the front section of the ship type platform, the tower is mounted behind the ship type platform, and symmetrical vertical tail wings are arranged at the tail part of the ship type platform. When the impellers are distributed in upwind direction (downward direction) in front (back) of the tower, the inclined supporting rod is mounted on the leeside surface (windward side surface) of the tower. The offshore wind driven generator set can be structurally mounted in a shipyard, so that the offshore mounting difficulty is lowered and the cost is reduced, the mechanical yaw failure rate is low and the reliability is high. The tower structure has an obvious damping effect, and the anti-overturning capability of the tower can be improved by the inclined supporting rod.
