Optimal Control of MTMD in Floating Wind Turbine Stability Based on MIGA
摘要
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.关键词
