摘　　要：双机组浮式风电系统是一种新型海上风力发电装备,两台风力机之间存在显著的相互作用,且与平台和系泊之间的耦合效应明显。本文通过对OpenFAST进行二次开发,开发了适用于双机组浮式风电系统风–浪联合仿真模型,计算了10MW半潜式双机组浮式风电系统在湍流风与非规则波联合作用下的动态响应,并与单机组模型进行比较。结果表明双机组平台水平及倾角、平台纵摇平均值和最大值及标准差分别比单机组模型低79.62%、61.87%和48.93%。同时,双机组模型的系泊张力也更低,波动幅度比单机组模型低66.9%。因双机组模型的轮毂高度较低,在同一风况下整机发电功率比单机组模型低15.64%。但双机组模型在降低平台运动方面表现出巨大潜力,在风剪切更大的深远海区域可以减少平台用料而显著降低风能利用成本。The twin-turbine floating wind power system is a novel type of offshore wind energy conversion device,where significant interactions exist between two wind turbines and coupling ef-fects with the platform and mooring system.This study conducted a secondary development on OpenFAST and developed a fully coupled simulation model for the twin-turbine floating wind power system.An investigation has been carried out on the dynamic response of a 10 MW semi-submersible twin-turbine floating wind power system under the combined action of turbulent wind and irregular waves,and then compared with the single-turbine model.The results indicate that the twin-turbine model exhibits lower platform translational and rotational angles.Compared to the single-turbine model,the average,maximum and standard deviation of the platform pitch are reduced by 79.62%,61.87%,and 48.93%,respectively.Additionally,the mooring tension of the twin-turbine model is lower,with a fluctuation amplitude 66.9%lower than that of the single-turbine model.Due to the lower hub height in the twin-turbine model,the overall power generation is 15.64%lower than that of the single-turbine model under the same wind condition.However,the twin-turbine model shows great potential in reducing platform motions,which can lead to significant cost savings in wind en-ergy utilization by reducing material usage for the platform,particularly in deep offshore areas with higher wind shear effect.
