摘　　要：为高效利用海洋资源,促进多能源融合的新型浮式平台发展,提出一种适应深远海域的“风力机-光伏-网箱”浮式综合平台。基于FAST与AQWA耦合计算方法,建立风力机、光伏与网箱平台、系泊系统耦合数值计算模型,通过“光伏-网箱”组合模型与单一网箱模型的频域对比分析,探究光伏组件对综合平台水动力性能的影响,进一步考虑海洋环境风浪流联合作用,计算得到“风力机-光伏-网箱”浮式综合平台的动力响应。结果表明:光伏组件使组合模型附加质量和辐射阻尼峰值有一定增加,对一阶波浪力影响较小但会导致垂荡与纵摇方向的幅值响应算子(RAO)上升;风浪流联合作用下,上部风力机转子推力、叶尖挥舞偏移、塔基剪力和塔顶偏移均产生较大波动,下部光伏与网箱平台纵荡和纵摇方向响应幅值显著增加,对垂荡方向影响较小,但会引起平台迎风缆绳张力明显增大和背风缆绳张力相应减少;相比单一网箱平台,添加风力机、光伏组件同样会引起浮式综合平台迎风缆绳张力增加和背风缆绳张力减小。In order to efficiently utilize marine resources and promote the development of multi-energy integrated floating platform,a"wind turbine-photovoltaic-net cage"floating integrated platform is proposed to adapt the deep-sea application.Based on the coupled calculation method of FAST and AQWA,the integral numerical model of wind turbine,photovoltaic(PV)and net cage platform,mooring system was established.The influence of the PV module on the hydrodynamic performance of the integrated platform was investigated by comparing the frequency domain of"PV-net cage"integrated model and single net cage model.Considering the combined actions of winds,waves and currents,the dynamic responses of the"wind turbine-photovoltaic-net cage"floating integrated platform was further calculated.The results show that PV module causes the increase of the additional mass and the peak radiation damping of the integrated model,and has little effect on the first-order wave force but leads to the augment of the RAO in the direction of the heave and the pitch.Under combined actions of winds,waves and currents,the rotor thrust,blade tip flapping deviation,base shear force and tower top deviation of the wind turbine produce large fluctuations.The responses amplitudes of the PV and the net cage platform in the surge and pitch direction significantly increase,but slightly influences on the heave direction.Meanwhile,the axial tension of the windward platform cables remarkably amplifies,and the axial tension of the leeward platform cables reduces.Compared with the single cage platform,the addition of wind turbine and photovoltaic module will also increase the upwind cable tension and decrease the leeward cable tension of the floating integrated platform.
