| 摘 要： | 南水北调东线工程源头泵站扬程变化幅度大、变化频度高、年运行时数长，应实现经济运行。分析泵装置效率特性，提出大型泵站变速一变角综合经济运行理论，并给出运行方案。结果表明，与单一变速或变角经济运行相比，泵站实现变速一变角综合经济运行，平均泵装置效率可再提高1％～5％。

| Abstract: | Since the head of pump stations in the East Route Project of Water Transfer from North to South varies frequently and in a wide range, and the pump stations have long running time annually, economical operation should be realized. The efficiency characteristics of pump installation were analyzed. The theory of comprehensive economical operation of pump stations by adjusting rotational speed and blade angle was advanced, and the operation schemes were also put forward, which could increase pump installation efficiency by 1%~5% compared with those by only adjusting rotational speed or adjusting blade angle. |
