城市水工业系统泵站优化调度问题建模方法研究

针对常用泵站效率优化模型的不足，提出一种符合水泵并联运行特性的最小流量偏差模型，对比研究了用于城市水工业系统泵站优化调度的最小流量偏差模型和最小轴功率模型，结合大量仿真实验，较系统地总结了二者的特点及其适用范围，研究结果表明：流量偏差优化模型比最小轴功率优化模型在工程实用性方面具有更大的优势，因而具有广阔的应用前景。

On optimal scheduling modeling of urban water industry system

To remedy the defects of optimal scheduling model for water supplying pumping stations, an improved model based on flow difference minimization is presented, which satisfies the parallel characteristics of pumping stations. Optimal scheduling models of water supplying pumping stations are analyzed, based on least flow difference and least shaft power respectively. The simulation results show that the optimal model based on least flow difference is better than the optimal model based on least shaft power in engineering practicality.
