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

Abstract

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 is greatly improved, and the safe operation capacity of a large fan within the 30-year service life is guaranteed.

Description

technical field [0001] The invention discloses a wind power generation technology, which belongs to the field of clean energy wind power generation and the field of machinery manufacturing. [0002] Specifically, it relates to a cost-effective offshore floating yaw type wind power generation device with strong typhoon resistance, which can reduce the low cost of electricity per kilowatt-hour while improving the operational reliability of the wind turbine. Background technique [0004] Improving the earth's atmospheric environment, reducing greenhouse gas emissions, advocating the use of wind and solar energy and limiting the use of fossil energy are the mainstream of contemporary energy technology. [0005] In the 21st century, wind power has experienced a golden age of rapid development. In the past two decades, the single-unit capacity has developed from 1MW to 10MW, and it has also entered the deep-sea continental shelf from land. Basically, the maximum 3MW level of on...

Fighting against typhoons has become the biggest risk to the safe operation of offshore wind farms

[0007] In addition, although offshore wind resources are abundant, the manufacturing and installation costs of wind turbines remain high, which also hinders the exploitation and utilization of offshore wind power.

[0008] In the existing offshore floating wind turbines, the floating foundation still relies on anchor chains in many directions to stabilize and fix the wind turbines. Such pile foundations are very large and expensive.
