供水管网压力调控下的漏损形态响应与控制效能及应用

In the background of urban and rural water supply implementation in the process of urbanization, leakage control problems in water supply pipe network have become increasingly prominent. But the active leakage control pressure zone management and optimization of regulation theory are still in their infancy. The hydraulic analysis based on pressure-driven theory is not perfect in water supply pipe network, and the pressure response mechanism on pipeline leakage form is not yet clear. There is lack of theoretical and technical support on urban-rural integration pressure regulating and partition management and optimization in pipe network. In this study, it carries out water pressure management theory, and inproves the pressure-driven hydraulic analysis algorithm, focusing on leakage morphological response mechanism and control performance under pressure regulating. It further explores the pipe network pressure regulation partition management and optimization, develops leakage control and zoning regulation optimization decision support tools, and applys it to optimize the layout of urban and rural integration process in water pipe network, leakage control practices. The achievments will promote the development of network-related pressure management theory and technology, and promote China's water industry technical progress and scientific operation. It could be implementing low-carbon energy, resource conservation and social development concept, which has clear theoretical and practical significance.

我国目前正处于快速城市化进程中，在城乡一体化供水需求背景下，供水管网漏损控制问题日益突出。但面向漏损主动控制的压力分区管理和优化调控理论尚处于起步阶段，基于压力驱动的供水管网水力分析理论尚不完善，管网漏损形态对于压力的响应机制尚不清晰，城乡一体化供水的管网压力分区管理和优化调控缺乏理论和技术支撑。本研究针对上述问题，在国内外研究基础上，围绕压力管理理论开展，通过对供水管网压力驱动水力分析算法的理论改进，重点研究压力调控下供水管网漏损的形态响应机制和漏损控制效能。进一步探索管网压力分区管理和优化调控问题，开发压力状态与漏损控制潜力评估及分区调控优化决策支持工具软件。并将之应用于我国城乡一体化供水管网的优化布局、漏损控制实践，对推动管网压力管理相关理论技术发展，促进我国供水行业技术进步和科学运行管理，以及贯彻低碳节能、资源节约的社会发展理念，均具有明确的理论价值和实践意义。

本项目从实验出发，研究了单管道压力变化与漏损微观形态响应，研究了在不同研究条件下，漏损指数的大致取值，综合比较了现有的供水管网压力驱动水力分析理论，对压力驱动水力算法进行了改进，从而从宏观形态响应上研究了管网漏损表现形式，建立了物理管网漏损模型。本研究还研究并建立了基于漏损主动控制的供水管网优化分区与压力调控数学模型，提出了供水管网多目标分区方法和调压阀优化设计方法，并以此开发了基于压力调控的优化分区软件工具。项目提出的城镇供水管网多目标分区方法、调压阀优化设计方法等成果已在江苏省苏州市、上海市奉贤区、河南省郑州市等地的供水管网水力模型中得到了初步应用，并取得了一定的效果。目前，研究团队正在将提出的方法进行软件化，将方法编制成软件进一步完善，形成更为成熟的专业工具性应用软件。
