摘要
以基于ITI Barge平台的NREL 5 MW风力机为研究对象,通过在机舱配置调谐质量阻尼器(TMD),研究在环境载荷作用下TMD对海上漂浮式风力机塔顶位移和平台摇荡特性的稳定性控制效果。结果表明:TMD对漂浮式风力机塔顶前后位移的控制效果不明显,对塔顶侧向位移的控制效果较明显,其最大值降低了66%,稳定性提高了38%;在TMD控制下,漂浮式风力机平台横荡和横摇降幅明显,其最大值分别降低了29%和45%,稳定性分别提高了18%和41%。
Taking the NREL 5 MW floating wind turbine with ITI Barge platform as an object of study, by equipping a tuned mass damper （TMD） in the nacelle, the control effects of TMD on the tower top dis- placement and platform sway characteristics were researched under environmental loads. Results show that TMD does not have an obvious effect on the control over back-and-forth displacement of the tower top, but it does have a remarkable influence on the lateral displacement, with a reduction in maximum value by 66%, and an increase in stability by 38%. Under the control of TMD, significant decline can be obtained for the floating wind turbine in platform sway and roll, with a reduction in maximum values of sway and roll by 29% and 45%, respectively, resulting in an increase in stability by 18% and 41% accordingly.
