摘要
提出一种用于漂浮式风力机的新型双索系泊系统,研究其对减少漂浮式风力机平台动态响应的有效性及系泊系统本身的力学性能。算例所采用的漂浮式风力机为OC4-DeepCwind三浮筒半潜式风力机,通过OrcaFlex软件建立相应风力机模型和两种系泊系统(原始单索系泊系统和新型双索系泊系统)。在一定海况条件下对比研究双索系泊系统相比于原始单索系泊系统对减少漂浮式风力机平台动态响应的优势。结果表明:相比于原单索系泊系统,双索系泊系统漂浮式风力机的振动响应有明显降低,但改变缆索预张力和副索导缆孔位置对漂浮式风力机振动响应影响不明显。
A double-cable mooring system for floating wind turbines was proposed and the dynamic response of the floating wind turbine platform with this mooring system and its own performance were investigated.The floating wind turbine used in this study was OC4-DeepCwind three-buoy semi-submersible wind turbine.The OrcaFlex software was used to build the corresponding wind turbine model and the models of two kinds of mooring systems(the original single-cable mooring system and the new double-cable mooring system).Under a certain ocean condition,the effects of the two kinds of mooring systems on the dynamic response suppression of the floating wind turbine platform were investigated.The results show that the vibration response of the floating wind turbine is significantly reduced by the double-cable mooring system compared with the original one,but the influence of the cable pre-tensile force and the position of the fairlead on the vibration response of the floating wind turbine is small.
