    摘要:

    对深海大兆瓦级浮式海上风电结构设计分析中的关键问题进行研究。浮式风电支撑结构采用美国国家可再生能源实验室(NREL)的OC3 Spar平台为基准模型。分别选用5 MW、6.7 MW和8 MW风机,采用比例因子设计法提出对应浮式支撑结构设计方案。考虑风荷载与波浪荷载联合作用,进行操作工况和极限工况下浮式支撑结构水动力分析及强度分析,分别得到支撑结构响应幅值算子(Response Amplitude Operator,RAO)和结构关键节点应力响应随风机功率变化规律。提出大兆瓦浮式风电结构应力消减方案,经过验证,改进后结构应力显著降低。

    Abstract:

    The key issues in design of deep-sea large-megawatt floating offshore wind power structures are focused on. The OC3 Spar platform of the National Renewable Energy Laboratory (NREL) is applied as the benchmark model of the floating wind power supporting structure. The 5 MW, 6.7 MW and 8 MW wind turbines are selected respectively, and the corresponding floating supporting structure design scheme is proposed using the scale factor design method. Considering the combined action of wind load and wave load, the hydrodynamic analysis and strength analysis of the floating supporting structure under operating conditions and extreme conditions are carried out, and the Response Amplitude Operator (RAO) of the supporting structure and the stress response of the critical nodes of the structure changing with the power of the wind turbine are obtained. The stress reduction scheme of large-megawatt floating wind power structure is proposed. After verification, the structural stress is significantly reduced after improvement.
