基于水力模型的供水管网区块化优化研究
|
摘要
为进一步优化配水系统分区,提出了一种基于多尺度分区算法的供水管网区块化优化方法。该方法考虑了供水管网系统的节点压力信息,改进了分区评价函数,并结合城市供水管网实际情况进行分区。以A市为例,利用EPANET建模器建立供水管网水力模型,在此基础上结合配水系统分区理念,将A市供水管网分为了11个区块。结果表明,分区后的供水管网实现了单独区域水量计量,缩小了查找漏失范围;管网压力更加趋于均衡,降低了漏失水量和产销差,使供水管网运行更加科学化、合理化。研究成果可为供水管网分区优化管理提供参考。
In order to further optimize DBS partition,a block optimization method of water supply networks is proposed based on multi-scale partition algorithm.This method takes the node pressure information of the water supply network system into account,improves the partition evaluation function,and combines with the actual situation of urban water supply network.Taking City A as an example,a water supply network hydraulic model is established by using EPANET modeler.On this basis,the water supply network of City A is divided into 11 blocks according to the concept of DBS partition.The results show that the flow of the water supply network can be measured in a single area after the partition,and the range of finding leakage is narrowed down;The pressure of the water supply network tends to be more balanced,the water leakage and the production and marketing gap are reduced.Simultaneously,the operation of the water supply network becomes more scientific and reasonable.The research results can provide reference for the regional optimal management of water supply network.
