研究浮式风力机系统整体湿拖的运动及拖缆张力，建立浮式风力机系统的水动力模型，基于三维势流理论计算浮式基础的水动力。考虑风、浪、流环境载荷，计算拖航过程浮式基础运动、风机法兰倾角、机舱加速度、拖缆张力等关键参数，分析缆长、有义波高、谱峰周期等参数对计算结果的影响。结果表明，在给定的环境参数范围内，浮式风机运动符合限制条件；拖缆越短相同环境参数下拖缆张力越大，600 m 及以上缆长的拖缆张力相对稳定，受波浪参数影响较小。最后给出不同缆长作业的波浪参数限制条件，为浮式风机整体湿拖作业提供参考。
The motion and cable tension of wet towing of the floating wind turbine systems were studied. The hydrodynamic model of floating wind turbine system was established, and the hydrodynamic forces of floating foundation were calculated based on three-dimensional potential flow theory. Having considered wind, wave and current loads, the key parameters such as floating foundation motion, wind- turbine flange inclination, cabin acceleration and towing cable tension during towing were calculated. The influence of cable length, wave height and wave period on the calculation results was analyzed. The results show that within a given ranges of environmental parameters, the motion of the floating turbine meets restrictive conditions. The shorter the towed cable, the greater the towed cable tension under the same environmental parameters. The towed cable tension of 600 m and above is relatively stable and less affected by wave parameters. Finally, the limiting operating wave parameters of different cable lengths are presented. This study provides some suggestions for the wet-towing operation of the floating wind turbine.
