摘要
以DTU 10 MW风力机为研究对象,对现有的NREL 5 MW无撑杆的半潜浮式风力机支撑平台进行放大设计,用于支撑DTU 10 MW风力机;基于浮式风力机“气动-水动-控制-弹性”全耦合分析模型,使用FAST软件对DTU 10 MW浮式风力机系统在不同工况下的动力特性进行了分析,并与5 MW浮式风力机系统的动力特性进行了对比。研究发现:风力机大型化后,风荷载低频激励作用更为突出,且系统动力反应有所增加,但整体运动性能良好。
Taking the DTU 10 MW wind turbine as research object,the existing braceless semi-submersible platform for the NREL 5 MW wind turbine is enlarged to support the DTU 10 MW wind turbine. Based on the aero-hydro-servo-elastic full coupling calculation model,the dynamic characteristics of 10 MW floating wind turbine system under different working conditions are analyzed by using FAST,and is compared with the dynamic characteristics of 5 MW floating wind turbine. The results show that,the low-frequency excitation of the wind loads is more prominent with the increase of wind turbine size,and the dynamic response of system is increased,but the overall motion performance is good.
