摘要:
将调谐质量阻尼器(TMD)引入海上浮动风力机结构动力学控制领域,建立了浮动风力机的气动-水动-控制-TMD-结构完全耦合动力学模型,对典型5 MW驳船型浮动风力机进行了TMD参数优化和振动控制研究;通过对5种典型风浪联合载荷工况、有/无配置TMD的风力机的动态响应仿真,研究了TMD的振动抑制效果。结果表明:优化设计的TMD在100 s内使风机塔顶纵向挠度的标准差降低45.7%;TMD使塔根纵向载荷、塔顶纵向挠度标准差降低20%~50%;使叶根纵向载荷、叶尖纵向挠度标准差降低10%~40%。因此,该TMD控制策略可显著减小海上浮动风力机各关键部位的振动响应及载荷。

Abstract:
In order to suppress the responses of the large vibration loads and deflections of the offshore floating wind turbine under the extreme wind and wave conditions,a passive tuned mass damper(TMD) is introduced to the dynamics control field of the floating wind turbine,and the fully coupled aero-hydro-control-TMD-structural dynamics model of the floating wind turbine is established in this paper. Parameter optimization of the TMD is researched based on the typical 5MW barge-type floating wind turbine. Five typical combined wind and wave load cases are selected under normal running state of the wind turbine; the dynamic responses of the wind turbine with/ without TMD are simulated and the suppression effect of the TMD is investigated. The results and their analysis show preliminarily that: ①The standard deviation of the tower top longitudinal deflection is decreased 45.7% in 100 seconds by the optimized TMD,so the optimized TMD can suppress the vibration in the form of the most important modal effectively. ②The suppression rates of the standard deviation of the longitudinal loads at tower base and deflections at tower top are 20% ~ 50% and those of the longitudinal loads at blade root and deflections at blade tip are 10% ~ 40% by the optimized TMD,which show that the optimized TMD can reduce the vibration loads and deflections of the key parts in wind turbine significantly under actual environmental conditions.
