| 以桑迪亚国家实验室公开的SNL-13. 2 MW半潜浮式风机计算模型为研究对象，采用Openfast软件对浮式风机进行“气动—水动—控制—弹性”全耦合时域仿真模拟，研究分析变化波高与风速对13. 2 MW风机运动特性产生的影响，并与同工况下10 MW风机的运动特性进行比较。研究发现: 在不同湍流风不规则波作用的工况下，SNL-13. 2 MW半潜浮式风机系统的纵荡、纵摇、垂荡响应幅值对波高变化不敏感，对风速变化较敏感，与同工况下10 MW风机的运动响应差异较小；在恶劣工况下，风机系统的波动幅值基本符合风机安全工作规范要求，满足风机的安全运转条件。 |

| The computational model of SNL-13. 2 MW semi-submersible floating wind turbine published by Sandia National Laboratories is used as the object of study, and the fully coupled "pneumatic-hydraulic-control-elasticity" time domain simulation of the floating wind turbine is carried out by Openfast software. The influence of changing wave height and wind speed on the motion characteristics of 13. 2 MW wind turbine is studied and analyzed, and it is compared with the motion characteristics of 10 MW wind turbine under the same working conditions. It is found that the amplitude of swing, pitch and heave response of SNL-13. 2 MW semi-submersible wind turbine system is not sensitive to the change of wave height, but sensitive to the change of wind speedunder different working conditions of turbulent wind irregular waves, and it has little difference from the motion response of 10 MW wind turbine under the same working conditions. Under harsh working conditions, the fluctuation amplitude of the wind turbine system basically meets the requirements of the fan safety work specifications and meets the safe operating conditions of the wind turbine. |
