摘要
针对多热源环状管网水力计算复杂繁琐的问题,基于地理信息系统(GIS)对多热源多环复杂热网进行建模和仿真。提出了应用Geodatabase数据模型,快速生成热网关联矩阵和独立回路矩阵,然后使用基本回路法计算热网水力工况。当供热管网发生爆管事故时,将此法应用到爆管事故后关阀方案的模拟研究,可以定量分析事故的供热影响,并比较不同位置处爆管的受影响程度。
In order to avoid the complicated calculation of hydraulic multi-source network,based on geographic information system( GIS),the network of multi-heat sources and multi-loops complex heating was modeled and simulated. By using geodatabase data model,the relating matrix and basic loop matrix of heat network were quickly set up,and hydraulic regime of heating network with the basic circuit was calculated. When pipebursting accident occured in heating network,the valve-shut off scheme was researched by simulation after tube-burst accident. The heating influence of the accident can be quantitative analyzed,also the degree of influence is compared when tube-burst accident happens at different place.
