半潜式浮式风电平台立柱波面爬升特性试验

Test on Wave Run-up Around Cloumn of Semi-submersible Floating Wind Turbine Platform

以新型3立柱半潜式浮式风机平台为研究对象,建立全耦合物理水池试验模型。采用水池模型试验对浮式风电平台各立柱附近波面爬升特性进行研究。结果表明:在线性频域范围内,当波浪周期小于17 s时立柱波面爬升幅值响应不受浪向影响;叶片旋转和塔筒耦合谐振激励对波面爬升没有显著影响;最小气隙主要发生在背浪向立柱,并且受系泊缆分布不对称影响。

Taken a new type three-column semi-submersible floating wind turbine platform as the research object,a fully coupled physical pool test model is established.The characteristics of wave run-up near each column of the floating wind turbine platform are studied through the pool model test.The results show that:in the linear frequency domain,when the wave period is shorter than 17s,the wave run-up around column is not affected by the wave direction;the blade rotation and tower coupling resonance excitation have no obvious effect on wave run-up;the narrowest air gap mainly occurs at the column in the back wave direction and is affected by the asymmetric distribution of mooring lines.
