摘要
基于弱海流,依据螺旋桨和风力发电的相关理论,分析叶轮流场特性,建立叶轮发电系统的数学模型。推导叶轮几何参数与其动力特性之间的关系,提出叶轮优化设计方法,分析叶轮发电系统总体性能。通过某一具体算例,设计并优化叶轮几何参数,选择合适的传动系统和电机,计算系统输出功率和效率。
Based on the weak marine current, the theory of propeller and wind - power genera- tion was used to analyze the flow field of turbine and establishes the mathematical model of turbine generation system. The design method and optimized design ideas of turbine are proposed and the performance of generator is analyzed on the basis of the model. At last, the turbine geometric parameters are optimized and the appropriate transmission system and generator are selected through a specific numerical example, then the output power and the total efficiency of the system are calculated.
