摘　　要：超临界二氧化碳(S-CO_(2))循环发电技术是未来发电市场极具前景的发展方向,透平是循环的核心部件,直接决定S-CO_(2)发电系统的动力性和经济性。借鉴蒸汽透平的设计理论和经验进行了300MW等级S-CO_(2)系统透平设计,利用哈汽公司高性能叶型数据库进行三维叶型设计。三维气动性能分析表明,S-CO_(2)透平气动性能优良,流量、效率、功率等指标满足设计要求。有限元分析表明,典型级动叶片应力、频率合格,设计方案可行。Supercritical Carbon Dioxide(S-CO_(2))power cycle is considered to be one of the most potential power conversion systems.Turbine,as the core component of the sysytem,determines the power and economy performance.In this paper an axial turbine for 300MW S-CO_(2) system is designed according to the theory and experiment of steam turbine,besides,3D blade is modeled referring to high-performance profile databases of HTC.The numerical simulation results indicate that the S-CO_(2) turbine has excellent aerodynamic performance and it can meet design requirements of mass flow,efficiency and output power.The FEA results indicate that the stress and frequency of typical blade is qualified and the design scheme is practicable.
