立洲水电站水轮机额定水头的优选方法

摘要

确定一个合适的水轮机额定工作水头，对于保障水轮发电机组的稳定运行和提高水电站运行的经济效益是至关重要的。以立州水电站水轮机选型设计为例，通过对不同额定水头方案水轮机的加权平均效率、投资、运行可靠性等的分析和比较，阐述了确定水轮机额定水头时应考虑的主要因素和优选方法。%The determination of a suitable turbine rated operating head is essential for ensuring stable operation of hydroelectric generating set and improving the economic benefits of hydropower station running. Lizhou Hydropower Station Turbine Selection and Design was taken as example, the weighted average efficiency, investment, operational reliability, etc. of different rated water head scheme turbines were analyzed and compared to describe the main factors and optimal methods which should be considered during determing the rated water head of turbines.
