基于爆管识别的压力监测点优化布置

Tube burst identification-based pressure monitoring points optimal layout

通过阐述压力监测点优化布置原则及思路,基于爆管事件数据库设定拟布置压力点数量。开展能够准确监测爆管事件且识别较多压力监测点的优化布置方法研究,并根据研究区管网概况构建爆管模拟水力模型,通过对爆管识别阈值的确定和监测点现状评估,分析新增压力监测点布置位置。最终分析确定了监测管径DN400以上,监测流量为300m^(3)/h的爆管,需要新增压力监测点50个,监测流量为400m^(3)/h的爆管,需要新增压力监测点20个。

The principle and idea of optimal layout of pressure monitoring points are elaborated in this paper,the number of pressure points to be arranged is set based on the data from pipe burst events,so that the number of monitoring points can be identified,and each pressure monitoring point can monitor as many monitoring points as possible.According to the general situation of the pipeline network in the study area,the simulation hydraulic pressure of pipe burst is constructed Based on the model,through the determination of pipe burst identification threshold and the evaluation of monitoring points,the layout area of new pressure monitoring points location.Finally,it is determined that for the burst pipe whose diameter is more than DN400,50 pressure monitoring points need to be added for the burst pipe whose monitoring flow rate is 300 m^(3)/h,for the monitoring flow is 400 m^(3)/h,15 new pressure monitoring points need to be added.
