摘要:
为了解决供水管网水力模型节点流量分配不准确的问题，基于J市供水管网水力建模项目提出新的节点流量分配方法,此方法先根据营业收费数据将供水区域划分区块，再利用GIS技术，采用“水表上溯”法找出用水量节点，该流量分配方法中的节点流量是营销节点流量和产销差节点流量之和。营销节点流量通过营销数据确定；在各个供水区域分别采用传统沿线流量法和人口密度法分配节点产销差流量。结果表明，两种方法所分配的节点流量都可满足流量监测点误差以及测压点相对误差要求，对比后发现应用人口密度法进行流量分配计算时，模型精度更高。
Abstract:
In order to solve the problem of inaccurate node flow distribution of water supply network hydraulic model, a new node flow distribution method based on a water supply network hydraulic modeling project in J city was proposed. This method first divided the water supply area according to the business sales data, and adopted GIS technology to find the water consumption node by using the “water meter up-tracking” method. Node flow in the allocation method was the sum of the business scales node flow and the non-revenue water node flow. Business scales node flow was determined by business scales data. The traditional linear flow method and the population density method were used to distribute the difference between the production and sales of the nodes in each water supply area. The node flow rate assigned by the two methods could meet the requirements of flow monitoring point error and pressure measuring point relative error. After comparison, it was found that the model accuracy was higher when the population density method was applied for the flow distribution calculation.
