基于多岛遗传算法的漂浮式风力机稳定性多重调谐质量阻尼器优化控制

摘要/Abstract

摘要： 将多重调谐质量阻尼器（MTMD）引入漂浮式风力机控制领域以提高漂浮式风力机的稳定性。以NREL 5MW风力机及ITI Barge平台为研究对象，提出在漂浮式风力机机舱和塔架中配置2个参数不同的调谐质量阻尼器（TMD），并基于多岛遗传算法，算出MTMD系统最优参数。通过对3种典型工况下、有无配置MTMD的漂浮式风力机进行模拟计算，研究了最优MTMD的控制效果。结果表明：多岛遗传算法能够有效优化MTMD参数；MTMD控制优于单一TMD控制；经参数优化后，MTMD对漂浮式风力机振动的控制效果更好，塔顶纵向位移和平台横摇角标准差抑制率分别提升了80.4%和83.8%；MTMD对漂浮式风力机不同部位的控制效果不同，控制效果最好的为塔顶纵向位移、塔根横向弯矩及平台横摇角；不同环境工况下，MTMD对漂浮式风力机都有着明显的控制效果，其中纵向载荷和位移的标准差抑制率分别为10.3%~12.1%和76.1%~78.3%，横向载荷和位移的标准差抑制率分别为75%~77.7%和8.9%~10.8%。

Abstract: MTMDs were introduced into the field of floating wind turbine controls to improve the stability of floating wind turbines.By NREL 5 MW wind turbine and ITI Barge platform as the research objects， two TMDs with different parameters in the nacelle and tower of the floating wind turbines were proposed.Based on the MIGA， the optimal parameters of the MTMD system were calculated.Based on the simulated calculations of three kinds of typical operating conditions， with or without MTMD were equipped with a floating wind turbine， the optimal control effects of MTMD were studied.The results show that MIGA may optimize MTMD parameters effectively and MTMD control is better than single TMD control.After optimization of parameters， MTMD has better control over the vibrations of floating wind turbines.The standard deviation inhibition rate of tower longitudinal displacement and platform roll angle increase by 80.4% and 83.8% respectively.MTMD has different control effects on different parts of floating wind turbines， and the best control position is the tower top longitudinal displacement， tower root lateral bending moment and platform roll angle.Under different environmental conditions， MTMD has obvious control effects on floating wind turbines.The standard deviation inhibition rate for vertical loads and displacements are 10.3% to 12.1% and 76.1% to 78.3% respectively.The standard deviation inhibition rate for lateral load and displacement are 75%~77.7% and 8.9%~10.8% respectively.
