摘要
基于一水泵水轮机的水轮机工况综合特性曲线,文章旨在提出一种数据驱动的三维综合特性曲线表达方法,并提出遗传模糊算法用于寻找最优运行点,基于文章所提出的方法,单位流量、单位转速、效率、导叶开度等关系得到了直观清晰的表达,最优运行范围也得到了有效确认,对电站高效运行、提高经济效益具有参考意义。
Based on the composite performance curve of a pump turbine,this article aims to propose a three-dimensional and data-driven composite performance curve expression method,and proposes the Genetic Fuzzy Algorithm to find the optimal operating point as well.Based on the methods proposed in this article,the relationships between unit flow rate,unit rotation speed,efficiency,and guide vane opening have been intuitively and clearly expressed,and the optimal operating range has been effectively confirmed,which has reference significance for efficient operation of power plants and improving economic benefits.
