城市供水系统调度优化新策略与应用

New Strategy and Application of Urban Water Supply System Scheduling Optimization

随着我国城镇化进程的加速和人民生活水平的不断提高,对城市供水系统提出了越来越高的要求。通过有效手段降低爆管概率甚至减少到零级,以此实现供水安全具有重大现实意义。以马鞍山市供水系统为例,基于冲量定理原则,通过对净水厂、加压站和用水大客户的供配水方式及调度方案进行优化升级,完成了供水系统的科学调度。自此调度方案实施一年多来,全市未发生自然爆管事故,实现了供水系统的“安全供水”目标。

The accelerating urbanization process and continuous improvement of people’s living standards lead to higher requirements for urban water supply system.It is of great practical significance to reduce the probability of pipe burst to zero by effective means,so as to realize safe water supply.Based on impulse theorem principle,the scientific scheduling of a water supply system in Ma’anshan was completed by optimizing and upgrading the water supply,distribution mode and scheduling schemes of waterworks,secondary pressurization pump stations and large water consumption customers.Since the implementation of the scheduling scheme more than a year,there has been no natural pipe burst incident in the city,and the safe water supply target of the water supply system has been realized.
