An operation decision method for multi - stage pumping station system with adjustable - blade propeller pump is presented . it includes optimal water level of individual stage of pumping station and optimal operation method of every pump . the paper describes some mathematical models and decision making technique of multi - stage pumping station 本文针对大型引水工程整个系统在进入稳态运行后，在各站的抽水流量或首级站进口水位发生变化的情况下及时做出运行决策，调整各梯级站间的水位，达到整个系统总能耗最小的目的。
Currently , there is a strong tention between energy and society development . our country consumed 335 million tons of standard coal in the year 1996 , it had a percentage of 24 of all the energy consumption . in the year 2001 , it has increased to 376 million tons of standard coil , increased by 0 . 05 % every year , and had a percentage of 27 . 6 % of all the energy consumption . from the year 2000 to the year 2015 , with the development of civil architecture the proportion of energy consumption will continue increase . generally about 40 % to 50 % of building energy is consumed in air conditioning system . the energy saving of building and hvac system has become an urgent problem to be solved in our country 1996年,我国建筑年消耗3 . 35亿吨标准煤,占能源消费总量的24 % ;到2001年,达到3 . 76亿吨标准煤,占能源消费总量的27 . 6 % ,年增加比例约为0 . 5 % ,而能耗指标仅为发达国家的1 / 3 。预测随着建筑业的高速发展,建筑能耗占总能耗的比例还会继续增长。建筑中空调系统的能耗占建筑总能耗的40 % 50 % ,因此要求降低建筑以及空调系统的能耗已经成为当前亟需解决的课题之一。
