摘　　要：提出了包括全部能源消耗在内的站系统效率概念,以及既包括水量损失又包括水力损失的渠系统效率概念.研究得出了单一调水单级泵站-渠道系统效率、调水-供水结合单级泵站-渠道系统效率、单一调水多级泵站-渠道系统效率、调水-供水-蓄水结合多级泵站-渠道-湖库系统效率的计算方法,进而形成了比较完整的调水工程效率计算方法体系.A conception of pumping station system efficiency is presented which includes all the energy consumption. A conception of canal system efficiency is established including the loss of water volume and head. This paper presents calculation methods of the efficiency of single-stage pumping station-canal system for water transfer, the efficiency of single-stage pumping station-canal system for water transfer and supply, the efficiency of multi-stage pumping station-canal system for water transfer, the efficiency of multi-stage pumping station-canal-lake reservoir system for water transfer, supply and storage. Therefore the calculation method system is formed for estimating efficiency of water transfer projects.
