摘　　要：在总结多级泵站系统工作组合方式的基础上,推导了多级泵站系统固有能耗参数和实际能耗参数的计算方法,其中固有能耗参数是指多级泵站系统无分流情况下的能耗参数。以东雷抽黄灌区2019年冬季灌溉新民多级泵站系统的实测数据为例,讨论了固有能耗参数与实际能耗参数之间的关系,分析了水泵机组及泵站系统的运行情况。对于一个固定组成的多级泵站系统,各水泵机组性能稳定情况下固有能耗参数为一定值,其实际能耗参数随工况变化而变化,固有装置效率通常小于实际装置效率。水泵机组及泵站系统的能耗参数可作为运行状态监测、最优运行调度方案和节能改造的标准,同时也可为灌区水价的制定及灌区财政补贴提供依据。On the basis of summarizing the working combination of the multi-stage pumping station system,the calculation methods of the inherent energy consumption parameters and the actual energy consumption parameters of the multi-stage pumping station system are derived,the inherent energy consumption parameters refer to the energy consumption parameters in the case of no diversion in the multi-stage pumping station system.Taking the measured data of the Xinmin system for 2019 winter irrigation in Donglei Yellow River pumping system as an example,the relationship between the inherent energy consumption parameter and the actual energy consumption parameter is discussed,and the operation of the pump unit and pumping station system is analyzed.For a fixed multi-stage pumping station system,the inherent energy consumption parameter is a certain value when the performance of each pump unit is stable,and its actual working efficiency varies with operating conditions.The inherent device efficiency is usually less than the actual device efficiency.The energy consumption parameters of the pump unit and the pumping station system can be used as standards for operating status monitoring,optimal operation scheduling and energy-saving transformation,and can also provide a basis for the formulation of irrigation district water prices and financial subsidies for irrigation districts.
