Problems solved by technology
[0004]
However, the floating wind turbine in the related art has the problem of limited yaw rotation angle. In addition, the overall yaw of the wind turbine tower is likely to cause problems such as excessive load on the yaw bearing, excessive volume, and inconvenient installation and maintenance.
[0005]
In addition, the floating platform has insufficient wind resistance when encountering strong winds at sea, which will cause further damage to the bearings

The invention provides a single-wind-wheel automatic yaw power generation system and a yawing control method thereof. The single-wind-wheel automatic yawing power generation system comprises a fan (10), a tower drum (20), a water platform (30), a mooring system (40) and a yaw controller, wherein the water platform (30) comprises a rotary supporting platform (31), a fixed connecting ring disc (32) fixedly connected with the rotary supporting platform (31) and a plurality of propeller yaw devices (33), an annular guide structure (321) is formed at the bottom of the fixed connecting ring disc (32), the plurality of propeller yaw devices (33) are evenly fixed to the outer circumference of the fixed connecting ring disc (32) and used for driving the water platform (30) to rotate, and the tower drum (20) is fixed to the rotary supporting platform (31). The annular guide structure is arranged on the water platform, so that an expensive yaw bearing for yawing is saved, and the single-wind-wheel automatic yaw power generation system is convenient to install and maintain, does not need shutdown operation, does not need a large installation ship, and is good in economical efficiency.
Description
technical field [0001] The invention relates to the technical field of wind power generation, in particular to a single wind rotor automatic yaw power generation system and a yaw control method thereof. Background technique [0002] As a renewable new energy, wind energy is attracting more and more attention due to its advantages of wide sources, large reserves and no pollution. As a special carrier of energy, electric energy has the characteristics of cleanness, high efficiency and environmental friendliness, so it is of great significance to vigorously develop new energy power generation. [0003] With the deepening of human understanding of offshore wind resources and the advancement of wind energy development technology, the development of wind resources has developed from near and shallow seas to deep and distant seas. Floating wind turbines are an important direction for deep-sea wind energy development, and the overall cost will be lower than that of traditional fixe...
