在供水系统实际运行过程中,调度人员往往根据实际需求,在当前水泵运行状态的基础上开启或关闭一台水泵,以调节管网中的压力和流量.人工经验的调度方式难以充分反映并结合管网中压力、流量的变化及实际需求,进而及时作出科学决策.针对此问题,提出了多水源泵站在线优化控制技术,建立了基于直接优化调度方法的在线优化控制模型,采用智能优化算法进行了求解,并确立了四项方案评价指标对在线优化控制方案进行评价.将所建立的模型,应用于南方城市供水系统在线优化控制中,验证了其实用性,并编制了相应的计算程序软件.
In the actual operation of the water supply system, dispatchers often turn on or off a water pump based on the actual demand of the pump to adjust the pressure and flow rate in the pipe network based on the current running status of the pump, and the manual experience scheduling method can not fully reflect and combine This paper puts forward the on-line optimization control technology of multi-water pump station and establishes the on-line optimization control model based on direct optimization scheduling method, and adopts the intelligent optimization algorithm And established four evaluation indexes to evaluate the online optimization control scheme.The model was applied to the on-line optimization control of urban water supply system in southern China, and its practicality was verified, and the corresponding calculation program software.
