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%。
The research on the stability of offshore floating wind turbine has gradually become the focus and hotspot of wind power research. Taking NREL (National Renewable Energy Laboratory) 5 MW wind turbine and ITI Barge platform as the research object, the whole model of offshore floating wind turbine is established. Through the configuration of TMD (tuned mass damper), the effect of its environmental load on Control effect of offshore floating wind turbine stability. The results show that: TMD has obvious restraining effect on the movement response of the floating wind turbine tower and platform. Under TMD control, the maximum displacement of the floating wind turbine tower top and bottom is reduced by 50% and the stability is improved by 38% Wind turbine platform roll and swing motion control effect is more obvious, the stability of the platform ramps increased by 18%, roll stability increased by 41%.
