渠系配水是一个复杂的动态过程,为此,建立了配水渠道流量优化调度0-1线性整数规划模型,并提出了各轮灌组引水时间均一化处理方法,使各轮灌组在同一引水时间结束灌溉,从而可使配水渠道进水闸能在同一时间关闭。模型运用于支渠以下各级配水渠道在来水流量确定,分水渠道流量彼此相同且按“定流量、变历时”方式轮灌时的优化配水方案决策。
As a complicated dynamic process, canal water distribution is a dynamic process. Therefore, a 0-1 linear integer programming model of water distribution channel flow optimization is established and a uniform treatment method of water diversion irrigation time is put forward. The time is over for irrigation so that the water distribution channel intakes can be closed at the same time. The model is applied to the decision of optimal water distribution scheme when water distribution channels at branches and sub-levels are under the condition of water flow rate determination, water diversion channel flow rate equal to each other and rotation according to “constant flow, variable time”.
