本文在长江潮位预报和感潮河道水流运动研究的基础上,根据大型立式轴流泵全调节性能特性,运用系统优化的原理和方法,建立了江都抽水站第四站在满足抽水流量要求的前提下,利用长江潮汐变化规律,进行经济性运行方案决策的优化模型,编制了电算程序。决策结果表明,在相同的运行条件下,优化运行方案与现行的运行方案相比,泵站提水单位流量所耗用的功率下降15％左右,泵站效率明显提高,经济效益显著。
Based on the research on the tidal level forecast of the Yangtze River and the study of the tidal current flow in the tidal channel, according to the characteristics of full regulation of the large vertical axial-flow pump and the principle and method of system optimization, the fourth station of Jiangdu Pumping Station was established to meet the requirement of pumping flow rate On the premise of using the tidal variation law of the Yangtze River, the optimization model of economic operation scheme decision-making is made and the computer program is compiled. The decision-making results show that under the same operating conditions, compared with the current operation scheme, the power consumption of pumping unit pumping unit drops by about 15%, the pumping station efficiency is obviously increased and the economic benefits are remarkable.
