摘要
为提高漂浮式风力机的稳定性,以NREL 5 MW风力机及ITI Barge平台为控制对象,在传统单个调谐质量阻尼器（STMD）基础上提出风力机机舱及塔架中配置不同动力特性调谐质量阻尼器（TMD）的新型多重调谐质量阻尼器（MTMD）控制方法,分别研究其在环境载荷作用下队海上漂浮式风力机稳定性的控制效果。研究表明：STMD及MTMD对漂浮式风力机塔顶左右位移控制效果较明显,波动范围分别减小38%和45%,稳定性分别提高41%和46%;在STMD及MTMD控制下,漂浮式风力机平台横荡和横摇降幅明显;MTMD对漂浮式风力机塔架和平台的动态响应控制效果优于STMD控制。
To enhance the stability of a floating type wind turbine, with a 5 MW NREL wind turbine and rH Barge platform serving as the object to be controlled, put forward was a novel MTMD method for controlling the wind turbine equipped with TMD in its cabin and derrick having various power characteristics on the basis of the conventional STMD and studied respectively were the results of the control over the stability of the offshore floating type wind turbine under the action of the environmental loads. The research results show that the STMD and MTMD will have a relatively conspicuous result in controlling the displacement at the top of the derrick of the floating type wind turbine along the left and right direction and the range of the fluctuation will decrease by 38% and 45% respectively and the stability will increase by 41% and 46% respectively. Under the control based on the STMD and MTMD, the swaying and rolling of the platform for the floating type wind turbine will decline conspicuously. The result of the control over the dynamic response of the derrick and platform of the floating type wind turbine based on the MTMD is better than that based on the STMD.
