摘要
本文以UpWind/NREL 5 MW为参考风力机,通过重新集成和改进FAST/Aerodyn气动、结构模块,结合Matlab/Simulink里搭建的PID控制器,自主开发了基于柔性尾缘襟翼(DTEF)的"智能叶片"整机气动伺服弹性仿真平台。在此基础上,研究了基于DTEF智能叶片系统降低IEC多种湍流风下疲劳载荷的有效性及其疲劳载荷减少情况。结果表明:无论是标准湍流风模型(NTM)还是极限湍流模型(ETM)下,所开发的智能叶片系统都有效地降低了疲劳载荷,其中,叶根挥舞弯矩和叶尖偏移量的波动都得到了有效的减少。
This paper presents a newly developed aero-servo-elastic platform,which was built by improving FAST/Aerodyn codes with the integration of an external deformable trailing edge flap PID controller into the Matlab/Simulink software.Based on the platform,the effect of smart rotor control on aerodynamic load reduction on NREL/Upwind 5 MW reference wind turbine was investigated under various operating wind conditions in accordance with the IEC standard.Results showed that, irrespective of Normal Turbulence Model（NTM） and Extreme Turbulence Model（ETM） cases, aerodynamic load in terms of blade flapwise root moment and tip deflection were effectively reduced.
