Description

Technical Field

[0001] The invention relates to the technical field of wind turbines, in particular to a built-in large-scale superconducting direct-drive wind turbine. Background Art

[0002] With the surge in global demand for clean energy and the leapfrog development of technology, large-scale built-in superconducting direct-drive wind turbines are gradually becoming a bright new star in the field of wind power generation, especially in extreme wind conditions and high-standard application environments such as offshore wind power. Their outstanding performance and unparalleled stability are attracting widespread attention and high recognition from the industry.

[0003] Modern wind turbines face severe challenges in terms of structural stability and power generation efficiency under extreme weather conditions, especially when strong winds are raging. This not only places higher demands on technical support capabilities, but also increases safety risks during operation, forcing the industry to constantly seek innovative solutions to cope with these complex and severe tests.

[0004] The towering towers and huge rotating blades of existing wind turbines are prone to significant dynamic shaking under strong winds. This shaking is then transmitted through complex mechanics, causing the base to vibrate violently. If there is a lack of effective shock-absorbing measures to alleviate this vibration, the long-term accumulated vibration energy will gradually aggravate the fatigue effect of the wind turbine base structure, causing material performance degradation and loose connection parts, and ultimately seriously threatening the overall stability and long-term service life of the wind turbine. Therefore, designing and implementing an efficient shock-absorbing system is crucial to ensure the safe and stable operation of wind turbines under extreme weather conditions.
