城镇中压燃气管网的在线动态仿真

摘要

为了更好的实时监测中压燃气管网,本文提出了基于SCADA系统对大型中压燃气管网的运行工况进行在线仿真,,通过节点流量变化系数的计算建立了中压燃气管网在线仿真系统模型,开发了软件系统,成功应用于宝鸡市中压燃气管网的在线仿真,经过长时间的应用证明技术运行稳定,模拟计算误差均在5％以内,可以满足运行工况监控和调度管理的需要.%In order to better real-time monitoring of medium gas pipe network, the article introduces the mathematical models of on-line simulation software based on node flow calculation of the coefficient of variation. The software has been successfully applied to Baoji city gas network system. The examples of project show that the software is stable and has high accuracy, and that the simulation error is less than 5%.
