摘　　要：[目的]为实现漂浮式风力机“降本增效”,提出一种新型双叶轮漂浮式风力机,即采用混合结构叶片的双叶轮漂浮式风力机。[方法]基于自由涡尾迹方法研究其在平台静止和运动状态下的气动特性。[结果]结果表明,无论平台静止还是运动,采用混合结构叶片的双叶轮漂浮式风力机在2种不同叶轮布置形式下的总功率均较传统单叶轮具有一定优势,同时能在一定程度上降低风力机叶片的成本。其中,混合结构主叶轮上风向布置配合常规副叶轮下风向布置为最优方案。[结论]研究成果可为海上风电的降本增效提供一定参考。[Purpose]In order to reduce the cost and improve the efficiency of floating wind turbines,this paper introduces a novel dual-rotor floating wind turbine with hybrid structure blades.[Method]The aerodynamic characteristics of the turbines without and with platform's motion are investigated by the free vortex wake method.[Result]Results indicate that,whether without or with platform's motion,the dual-rotor floating wind turbine with hybrid structure blades demonstrates certain advantages in total power output compared to traditional single-rotor designs,while also reducing the cost of the blades.Among the configurations analyzed,the optimal arrangement is identified as the combination of hybrid-structural upwind main rotor with the conventional downwind auxiliary rotor.[Conclusion]The research can provide a certain reference for cost reduction and efficiency improvement of offshore wind power.
