AI Technical Summary
Existing wind turbine liquid damping devices have insufficient adaptability, limited damping characteristics, and are prone to inducing local resonance. They are difficult to balance dynamic suppression and unit output stability, resulting in power generation fluctuations and affecting the stability of the power system and energy storage regulation.
The sloshing damping device, which adopts a liftable baffle, dynamically controls the liquid distribution and damping characteristics in the sloshing tank through a dual-liquid stratification design and baffle height adjustment, adapting to different operating conditions and reducing tower vibration response and generator set fluctuations.
It improves the vibration suppression capability and service life of wind turbines, reduces power generation fluctuations, enhances the coordinated operation stability of wind turbine units and energy storage systems, reduces component impact damage, and extends the life of the equipment.
