摘要
为探究风轮-机舱组件(RNA)运行作用对近海风电结构调谐质量阻尼器(TMD)振动控制的影响,以NREL 5 MW单桩风电塔为对象,基于风-浪-流-RNA运行耦合的近海风电结构分析模型,通过定点理论对风电塔架一阶频率设计TMD参数。结合RNA控制策略下风电机组的时变振动特性,分别研究TMD对近海风电结构塔顶前后向及侧向动力响应的控制机理。结果表明:由于前后向与侧向动力条件的不同,TMD无法有效控制塔顶前后向振动,但可显著抑制塔顶侧向振动响应。
In order to explore the influence of rotor-nacelle assembly(RNA)operation on tuned mass dampers(TMD)vibration control of offshore wind turbine,this paper designs TMD parameters using the first-order frequency fixed-point theory,based on the wind-wavecurrent-RNA operation coupled offshore wind turbine analysis model.Combined with the time-varying vibration characteristics of the wind turbine under the RNA control strategy,the control mechanism of TMD for the for-aft and side-side dynamic responses of the tower top was studied respectively.The results show that TMD cannot effectively control the for-aft vibration,but can significantly suppress the side-side vibration response of the tower top,due to the different dynamic conditions between the for-aft and side-side directions.
