随着固定基础风电机组已不能满足深海电站的设计和造价要求,适合海上浮式风电机组的风电机组得到了迅速发展。在有限元分析软件Ansys-AQWA中建立了Spar Fowt模型,研究了五种工况下不规则波的频谱峰值频率和入射角度对Spar FoWT振动响应的影响。在相似理论的指导下,对典型工况下的1/150缩尺模型进行了模拟计算。结果表明,频谱的峰值频率对FOWT的振动响应有显著影响,入射角对其影响较小。将塔顶纵向位移的最大值和标准差与物理模型和实验模型进行比较,最小误差分别为3.60%和3.56%。为浮式风力机振动的实验研究奠定了基础。
As the fixed foundation wind turbine no longer meets the design and cost requirements in deep sea power plant, and the offshore floating wind turbine (FOWT) suitable has been developed rapidly. The spar FOWT model is established in ANSYS-AQWA, and the influences of spectral peak frequency and incident angle for irregular waves on the vibration responses of FOWT are studied under five load cases. Under the guidance of similar theory, 1/150 scaled model has been simulated under typical load cases. The results show that the peak frequency of the spectrum has a significant effect on the vibration responses of FOWT, the incident angle also has a slight effect. By comparing the maximum and standard deviation (SD) of the tower top fore-aft displacement (TTDspFA) with the physical model and the experimental model, the minimum errors are 3.60% and 3.56%, respectively. This work will lay a foundation for experimental study on vibration of the floating wind turbine.
