基于TMD的海上漂浮式风力机稳定性研究

海上漂浮式风力机的稳定性研究已逐渐成为风电研究的重点与热点。以NREL(国家可再生能源实验室)5 MW风力机及ITI Barge平台为研究对象,建立海上漂浮式风力机整机模型,通过配置TMD(调谐质量阻尼器),研究其对环境载荷作用下的海上漂浮式风力机稳定性的控制效果。结果表明:TMD对漂浮式风力机塔架和平台的运动响应有明显的抑制效果,在TMD控制下,漂浮式风力机塔顶左右位移最大值降低近50%,稳定性提高38%;对漂浮式风力机平台的横摇及横荡运动控制效果较明显,平台横荡稳定性提高18%,横摇稳定性提高41%。

Research on the Stability Control of Floating Wind Turbine based on TMD

The research on the stability of offshore floating wind turbine has become the focus in the field of wind power research. In this paper,the parameters of NREL 5MW wind turbine and platform are used to build wind turbine model and to study the control effect of the stability of floating wind turbine through the configuration of TMD(tuned mass damper).The results show that TMD can significantly inhibit the response of floating wind turbine tower and platform. Under the control of TMD,the maximum value of the tower top side-to-side displacement of the floating wind turbine is reduced by nearly 50%,and the stability is improved by 38%.The control effect of roll and sway motion of the platform is more evident; the sway stability of the platform is improved by 18% and the roll stability is increased by 41%.
