摘要

摘要: 供水管网漏失是国内外普遍存在的问题。如何有效降低管网漏失率、定位漏失发生的位置,是困扰我国供水行业的一个重要问题。基于水力模型和在线监测数据的管网漏失定位方法能够较快地对管道漏失事件进行侦测识别,并实现初步定位,但该类方法较为依赖水力模型精度,同时缺乏足够的实际管网漏失案例监测数据进行检验。通过搭建实验室管网模型,布设SCADA系统用以监测压力、流量数据,从而实现对城市供水管网的模拟,以生成各类管网漏失的模拟数据,用于检验漏失定位方法的有效性。同时,通过改变漏失位置及漏量、模型精度、监测点优化布置方式,进行漏失定位效果的比对,分析了影响漏失定位效果的因素。

Abstract: Leakage in water distribution network (WDN) is a common and worldwide problem.How to effectively reduce the leakage rate and locate the leakage is an important problem which perplexing China's water supply industry.The leakage location methods based on hydraulic model and online monitoring data can quickly identify the leakage events in WDN and achieve preliminary location.However,such methods depend heavily on model accuracy,and also lack sufficient actual leakage case data in WDN for testing.To address this,the laboratory pipe network model was built in this study,and the SCADA system was arranged to monitor the pressure and flow data,so as to realize the simulation of WDN,which can be used to generate the simulation data of various leakage in WDN and test the effect of leakage location method.Moreover,by changing the leakage location and flow,model accuracy,as well as optimal layout of monitoring points,this study identified the influencing factors of the leakage location.
