为研究水轮机安装位置对Spar式风-流互补系统耦合动力学特性的影响，基于开源软件OpenFAST和商用软件AQWA建立了浮式风-流互补系统气动-水动-伺服-弹性全耦合仿真模型，分别计算了水轮机安装于水平面以下70m、80m、90m、100m和110m处的平台运动、系统输出功率及系泊张力，并与无水轮机时的计算结果对比分析。结果表明：当水轮机安装于水平面以下110 m时，比无水轮机时平台纵摇标准差降低了11.58%，系统输出功率增加10.11%。说明浮式风-流互补系统在提升功率的同时，还可以增强系统运动稳定性。

In order to investigate the influence of installation position on the dynamics of the Spar integrated wind-current energy system, this paper established a fully coupling model of integrated floating energy system based on the open source software OpenFAST and the commercial software AQWA. The platform motion, system power and mooring tensions are calculated for the cases in those the tidal turbines are installed at 70m, 80m, 90m, 100m and 110m below the mean sea level, respectively. The simulation results analyzed and compared with those obtained for the floating offshore wind turbine. The results show that when the tidal turbines are installed 110m below the mean sea level, the standard deviation of the platform pitch is reduced by 1.58% compared with the results in the case without tidal turbines. The output power of the system increases by 10.11%. The results indicate that the integrated floating wind-current energy system is not only capable of improving the power output, but also of enhancing the stability of the system.
