Floating yaw type anti-typhoon wind power generation device and typhoon defense method

The invention discloses a low-cost floating yaw type anti-typhoon wind power generation device and a typhoon resisting method, and provides a low-cost structure configuration and control strategy for improving the anti-typhoon capacity and reducing the degree of typhoon, and the characteristic that a floating system can freely rotate on a water body without a bearing and a rail is utilized. A set of expensive yaw bearing and control system of a traditional fan is omitted, the cost of a tower drum and a transmission chain structure can be further optimized through the self-adaptive directional stress state, and a structure that blades of a wind wheel can be put down and folded together under the typhoon condition is constructed. And in combination with control of the yaw system and the downwind blowing effect of wind power, all the blades point to the downwind direction in the typhoon environment, the upsetting moment of the wind power device is balanced, and therefore the typhoon disaster resisting capacity i
