摘要
为支撑DTU 10 MW风力机,对5 MW无撑杆半潜浮式风力机支撑平台进行了放大设计,并对10 MW半潜浮式风机的伺服控制系统重新设计。其中,在额定风速以下实施转矩控制,以实现最大功率捕获;在额定风速以上,基于增益调度比例积分(GSPI)控制方法进行变桨控制系统设计,以保证浮式风机的安全运行。基于所设计的10 MW浮式风机伺服控制系统,采用“气动-水动-控制-弹性”全耦合模型对10 MW半潜式风机在恒定风和湍流风作用下的耦合动力特性进行了分析,验证了所设计控制系统的可靠性。研究发现,在伺服系统控制作用下,10 MW浮式风机的运动响应得到有效控制,湍流风对浮式风机的纵荡和纵摇激励作用明显,垂荡运动受到风载荷和波浪的共同激励。
The braceless semi-submersible platform for the NREL 5 MW wind turbine is upscaled to support the DTU 10 MW wind turbine in this study.The servo control system of 10 MW semi-submersible wind turbine is redesigned,in which,the torque control is used to achieve maximum power capture below the rated wind speed,and the gain scheduling proportional integral(GSPI)control method is used to realize the design of variable propeller control system above the rated wind speed,so as to ensure the safe operation of the floating wind turbine above the rated wind speed.Based on above designed servo control system of the DTU 10 MW wind turbine,the coupled dynamic characteristics of 10 MW semi-submersible wind turbine under the action of constant and turbulent wind are analyzed by using the full coupling model of"Aerodynamics-hydrodynamics-control-elasticity"for verifying the reliability of the designed control system.The results show that,under the action of servo control system,the motion response of 10 MW floating offshore wind turbine is controlled effectively,the turbulent wind has obvious excitation effect on the surge and pitch of the turbine,and the heave motion is excited by both wind loads and wave loads.
