漂浮式风力机是一种新型风力机。在海上风和波浪的综合作用下,机组的运动和气动特性参数将产生显著的动态变化,即动态响应。本文利用气动、水动、控制、结构完全耦合的风力机模拟软件,对三种典型漂浮式风力机在不同的风和波浪条件下的动态响应进行了计算和分析,结果表明:不同类型漂浮式风力机的动态响应差别很大,但纵荡运动始终是最主要的运动形式,纵荡平衡位置主要受风速的影响,而纵荡振幅主要受浪高的影响;漂浮式风力机的平均功率相对固定式风力机的稳态值基本不变,但平均载荷有较大程度的增加。
Floating wind turbine is a new type of wind turbine. Under the combined action of sea wind and wave, the dynamic and aerodynamic characteristics of the unit will have a significant dynamic change. In this paper, the dynamic responses of three typical floating wind turbines under different wind and wave conditions are calculated and analyzed by using pneumatic turbine, hydro-dynamic control and structurally fully coupled wind turbine simulation software. The results show that different types of floating The dynamic response of the wind turbine varies greatly, but the longitudinal movement is always the main form of movement. The position of the longitudinal oscillation is mainly affected by the wind speed, while the amplitude of the longitudinal oscillation is mainly affected by the wave height. The average power of the floating wind turbine is relatively The steady-state value of fixed-type wind turbine is basically the same, but the average load has a greater degree of increase.
