摘要
近海环境复杂多变,风和波浪的综合载荷会对浮式风力涡轮机平台和塔顶产生较大振动,严重威胁风力涡轮机系统的结构安全。为了应对这一挑战,在驳船浮式风力涡轮机的机舱内安装了一个调谐质量阻尼器(tuned mass damper,TMD),并通过采用H∞控制算法利用主动驱动力形成混合质量阻尼器(hybrid mass damper,HMD)。通过仿真比较了无控制、被动控制和H∞控制的效果,结果表明H∞控制能有效减小平台纵向角度和塔顶纵向位移,抑振效果明显。
The offshore environment is complex and volatile,and the combined wind and wave loads can generate large vibrations on the floating wind turbine platform and tower top,posing a serious threat to the structural safety of the wind turbine system.To cope with this challenge,a tuned mass damper(TMD)was installed in the nacelle of the barge floating wind turbine to form a hybrid mass damper(HMD)using active driving force.The H∞algorithm was used for the drive force control.The effects of no control,passive control,and H∞control were compared through simulation.The results show that the H∞control can effectively reduce the longitudinal angle of the platform and the longitudinal displacement of the top of the tower,with obvious vibration suppression effects.
