摘　　要：针对浮式风力机受到各种复杂载荷而产生的稳定性问题,通过在5 MW Barge风力机机舱内配置调谐阻尼质量器(TMD),利用FAST模拟结构的动力特性,研究TMD对海上浮式风力机平台运动特性、塔顶位移以及塔架根部载荷的控制效果。此外,基于遗传算法对TMD结构参数进行优化,并比较了在无控制、无优化TMD控制以及优化TMD控制下浮式风力机的运动响应。基于实测海况数据,对优化后的TMD进行了合理性与可靠性验证。结果表明:相较于无优化TMD,优化后的TMD对浮式风力机横摇、塔顶侧向位移以及塔架根部侧向载荷控制效果更加明显;优化后TMD可以适用于大部分海况,能够很好地控制高频区间时运动响应的幅度,并且随着海况等级的提高,对浮式风力机运动响应控制效果更加明显。结果表明了TMD控制方法与优化算法的可靠性与优越性。Focusing on the stability problem of floating wind turbine subjected to various complex loads,by equipping a tuned mass damper(TMD)on the nacelle of the 5 MW Barge wind turbine and using FAST to simulate the dynamic performance of the structure,this paper is to investigate the control effect of TMD on the motion characteristics,tower top displacement and tower root load of floating wind turbines.In addition,the TMD structure parameters were optimized based on the Genetic Algorithm.Meanwhile,motion responses of floating wind turbines without the control,with the non-optimized TMD control and with the optimized TMD control were compared.Based on the measured sea state data,the rationality and reliability of optimized TMD were verified.The results show that compared with the non-optimized TMD,the optimized TMD is more effective in controlling the roll,the side-to-side displacement at the tower top and the side-to-side load at the tower root.The optimized TMD can be applied to most sea states and can well control the amplitude of motion response in the high frequency interval of sea state.Besides,with the improvement of sea state level,the control effect of motion response for the floating wind turbine becomes more obvious.The results show the reliability and superiority of TMD control method and optimization algorithm.
