【摘要】 本文介绍了城市给水系统优化调度技术的主要内容,并对优化调度的基础,如用水量预测模型,管网模型和优化调度模型进行了深入的研究。 针对时用水量预测模型,采用季节指数法、自适应指数平滑法、季节指数联合自适应过滤法、指数平滑联合自回归法、季节指数联合灰色系统法等具体预测方法,其中数种方法预测精度达到工程要求。实践结果表明,开发的联合法效果较好。考虑到管网宏观模型不但能描述整个管网的工作状态,而且建模所需成本低,运行速度快,省时省力,主要研究了管网宏观模型的建立方法,分析测压点布置原理并编制程序。在研究优化调度方法时,研究了两级优化调度方法。根据优化调度模型的特点,提出了求解模型的多种算法。 最后根据优化调度方法的主要内容,编制了优化调度模型系统软件,该软件具有模块化、结构化、可视化特性。用榆次市的给水系统作为工程实例,对该市的给水系统进行短期优化调度,结果表明,榆次市优化调度结果具有明显的节能意义,说明该优化调度模型软件的开发是成功的。

【Abstract】 Methods for optimal operation of pumping stations in municipal water supply system were introduced, it consider the model as the base of optimal operation. The method comprises of three components, namely ,prediction model for hourly water of the entire network, model of water distribution system and optimization model. Hourly water demand prediction of distribution system was mainly studied. The paper analyze many methods of water demand prediction which include many up to date methods and some in common use, and it bring forward some new combinatorial methods which can meet the need of optimization model in precision, such as season exponent, auto adapt filter, season exponent combined grey model, etc. Based on the cost and time of modeling Jt mainly study the macroscopic network model which describes the correlation between nodal pressures and water plant discharge. When a complex water supply system use optimization model, the secondary series of discrete optimization will be adopted for modeling and solving it easily. Many computational methods about the optimization models were researched.finally, software of optimal operation was developed based on the optimization methods in water supply system. Modularization, better frameworks and visualization are the characters of this software. Appling these methods and the software to water supply system in Yuci city, the result show that the short term optimization is feasible. The development of software for optimal operation of water supply system is successful and application can reach the result of saving energy.
