摘要:
大型管网的日趋复杂和多水源的供水结构导致了水量调度有诸多不确定性因素，而有效分区是可行的解决方法。利用基于围绕中心点的划分（PAM）改进的二分K-means模型实现了大型管网的聚类分区，并结合“手肘图”得到了科学的分区方案；根据二八原则、最优切分算法对区域间重要管道进行识别，可以为分区阀门的关闭提供理论支撑；通过管道的流量响应分析了水厂调配能力及区域间的水量调配效率。将该方法应用到G市大型供水系统中，取得了良好的分区效果，为下一步区域间联合水量优化调度提供了决策依据。
Abstract:
The complexity of large-scale water supply network and multi-source water supply structure lead to many uncertain factors in water dispatch, and effective district-dividing is considered to be a feasible solution to solve this problem. The clustering district-dividing of large-scale water supply network was realized by using binary split K-means model modified by partitioning around medoid (PAM), and a scientific partitioning solution was obtained by combination with “elbow diagram”. The important inter-regional pipelines were identified according to the two-eight principle and the optimal segmentation algorithm, which could provide theoretical support for the closure of partition valves. The water dispatch capacity of water treatment plant and the efficiency of water dispatch between regions were analyzed through the flow response of pipeline. The method was applied to a large-scale water supply system in G city, and good performance was obtained, which provided a decision-making basis for the next step of inter-regional combined water dispatch optimization.
