【摘要】：对多泥沙水源泵站的优化调度,主要以清水条件下算出的泵站稳态数据为基础,在一定的含沙率和下游所需流量下,运用泥沙公式求出泥沙水源条件下各种组合的水泵工作点;然后采用动态规划法,以抽取单位水量的耗能量最小作为目标函数,确定约束条件和递推方程,接着对模型求解,找出最优的开机组合。以某取水泵站为例进行了相关计算,计算结果表明:采用动态规划法,并运用相关的公式求出工作点;利用计算机语言,可以快速并准确地在满足条件下所有的水泵开机组合型式中寻找出最优的开机组合,以减少泵站的损耗,提高泵站的运行效率。借助于工程实例,对于含沙水流下泵站工作参数的推导、动态规划数学模型的建立以及调度目标函数的确定等过程进行了较为详细的介绍。
[Abstract]:On the basis of the steady state data of the pump station under clear water condition, the optimal operation of the pumping station with sediment source is mainly based on the calculation of the pump station's steady state data under the condition of clear water. Under the condition of certain sediment content and the required downstream discharge, the working points of various kinds of combined pumps under the condition of sediment source are obtained by using the sediment formula. Then, by using dynamic programming method, the minimum energy consumption per unit of water is taken as the objective function, the constraint conditions and recursive equations are determined, and then the model is solved to find the optimal start-up combination. The results show that the dynamic programming method is used to calculate the working point and the computer language is used to find out the optimal start-up combination of all the pump start-up combinations quickly and accurately. In order to reduce the loss of the pumping station and improve the operation efficiency of the pumping station, the working parameters of the pumping station under the sand bearing flow are deduced with the aid of an engineering example. The establishment of mathematical model of dynamic programming and the determination of scheduling objective function are introduced in detail.
