供水管网实时分区及节流阀调度研究

为进一步降低供水管网漏损率,节约能源,提高水资源利用率,通过EPANET工具箱、Matlab及C#联合编程,以节流阀的开启度为影响因素,以漏失费用为目标,建立阀门实时调度模型。首先,该模型通过模糊C-均值聚类法(FCM)实时对管网进行分区;其次,对各区域内每一时刻的阀门开启度进行调整;最后,通过布谷鸟算法(CS)进行优化调度,从而均衡管网压力,降低管网漏失量。F市实际供水管网优化调度结果表明,优化后漏失率降低了11.96%,提高了水资源的有效利用率。研究成果对于供水管网优化调度意义重大。

Real-time Partition and Throttle Valve Scheduling in Water Distribution System

In order to further reduce the leakage ratio of water supply pipe network and save energy as well as improve utilization of water resources, based on EPANET toolbox, Matlab and C#, a real-time throttle valve scheduling model was established by taking opening degrees of throttle valve as influencing factor and leakage costs as objective function. First, water distribution system was divided into different zones based on FCM. Secondly, the opening degrees of each throttle valve zone were adjusted in every time. Finally, cuckoo search algorithm was used for scheduling, which can balance pressures of pipe networks and reduce leakage volumes. A case of City F is employed to verify the precision of this model. The optimal scheduling results demonstrate that the optimized leakage volumes are reduced 11.96%. So, the effective utilization of water resources is improved. The research has important significance for optimal scheduling of water supply pipe network.
