城市供水企业是耗电大户.研究供水系统的优化运行可以达到节能的目的.因此该研究具有重要的社会经济效益.本文引入多目标决策技术,建立了以供水水质、运行费用、水量平衡函数及投入运行水泵台数四个目标函数为基础的优化调度模型.该模型是一个混合离散变量非线性规划问题,可用MDOD法求解,对实际管网进行了优化计算,结果表明:该方法可直接计算含定速泵与变速泵的供水系统.具有明显的实用价值.
Urban water supply enterprises are large consumers of electricity. Researching the optimal operation of water supply system can achieve the goal of energy saving. Therefore, this research has important social and economic benefits. This paper introduces multi-objective decision-making technology and establishes a water quality, operating cost, and water balance function. The optimal scheduling model based on the four objective functions of the number of pumps is used. This model is a nonlinear programming problem with mixed discrete variables. It can be solved by MDOD method and the actual pipe network is optimized. The results show that this method can be directly calculated. The water supply system with fixed speed pump and variable speed pump has obvious practical value.
