摘要
以美国可再生能源实验室(NREL)研究所选用的5MW海上风力机为主要参考模型,概念性地提出一种新型张力腿-锚缆结合式系泊系统的浮式平台形式。综合考虑顶部风机响应、支撑结构和下部系泊系统的动力耦合作用,参照IEC 61400-3海上风力机设计规范中的典型设计工况,采用数值模拟的手段对新型海上风力机浮式平台进行风浪流联合作用下的时域分析。结果表明,新型张力腿-锚缆结合式系泊系统可很好地保障海上5MW浮式风力机的正常工作性能,其对未来海上浮式风力机的发展具有积极的指导意义。
Based on 5 MW offshore wind turbine model chosen by the National Renewable Energy Laboratory, a new conceptual offshore floating wind turbine structure with the combined tension legs-mooting lines system was pro- posed. Taking the coupled effect of dynamic response of the top wind turbine, tower support structure and lower mooring system into account, the time domain analysis with coupled wind-wave-current effects was applied to the new offshore floating platform by advanced numerical tools, according to the typical design conditions in IEC 61400-3 code. The results showed that, the new conceptual tension legs-mooring lines system can effectively ensure the performance of the offshore floating wind turbine, which would play an active and instructive role in the devel- opment of the offshore floating wind turbine.
