【摘要】 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.更多还原

【Abstract】 Water supply companies are large consumers of electricity. Optimal operation of water supply systems can save energy, therefore this research has important social and economical benefits.In this paper, multy-objective dicision technique is introduced. The optimal dispatch model Is based on four objective functions, which include the quality of supplying water, operation cost, balance function of water quantity and the number of operation pumps.The model is a mixed descrete variable non-linear programme problem, which can be solved by the MDOD method. The corresponding computations show that the method can directly solve the systems of both fixed-speed pumps and variable-speed pumps. The method has practical values.更多还原
