Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation, and in particular to a wind power generator set. Background Art

[0002] With the growing global demand for clean energy, wind power generation, as a key form of renewable energy, is garnering increasing attention. However, a major operational challenge for wind turbines is vibration caused by factors such as wind speed fluctuations and mechanical wear. This vibration not only affects the efficiency and lifespan of the equipment but can also pose safety risks. Therefore, research and development of effective vibration suppression and stability enhancement devices are crucial for improving the performance of wind power systems. Traditional wind turbine designs typically rely on robust mechanical structures to withstand the various challenges posed by the natural environment. However, this design approach has limitations, particularly when faced with complex and variable wind conditions. For example, sudden increases in wind speed or gusts can dramatically increase the load on the blades, causing additional vibration in the drivetrain and generator. Over time, this accelerates component wear and can lead to equipment failure. Furthermore, since wind turbines are often located in remote areas, maintenance costs are high and timely repairs are difficult to obtain, further highlighting the need for improved equipment stability and durability.
