摘　　要：针对柱状漂浮式风力机的结构振动控制展开研究。首先为进行调谐质量阻尼器(TMD)参数的优化,对风力机模型进行简化,并对简化模型中的未知参数进行估计;随后,基于简化模型分别使用公式法和遗传算法对TMD参数进行优化,并通过比较塔顶前后位移的标准偏差确定最终的优化方法;最后,为评估TMD对风力机振动控制的影响,构建风力机的联合仿真模型,并在3种典型工况下进行仿真分析。仿真结果表明,所设计的TMD可以很好地降低漂浮式风力机的载荷以及位移,有效抑制塔顶振动加速度与系泊缆绳有效张力,同时可有效降低额定风速以上时电功率输出的标准偏差,使电功率输出更加稳定。In this paper,structural vibration control of spar floating wind turbines are investigated. Firstly,wind turbine model is simplified to estimate and optimize tuning mass damper(TMD) parameters. Secondly,based on genetic algorithm,optimization method is determined by comparing standard deviation of tower top longitudinal displacement. Finally,in order to evaluate the influence of TMD on vibration,a joint simulation is constructed under three typical load cases respectively. Results show that TMD can effectively reduce loads and displacement,by suppressing the vibration acceleration at the top of the tower and mooring cable,which can significantly reduce the standard deviation of electric power and make it more stable.
