摘要
建立城市燃气PE管网核心部件流阻模型和网路结构分析模型;建立管网运行参数理论分析模型和泄漏检测分析、漏点定位分析模型;利用管道仿真软件PipelineStudio进行管网运行的动态仿真,研究管网不同工况下的泄漏规律,验证相关分析判漏和压差法漏点定位的可行性,评估了泄漏检测方法灵敏度。
In order to improve the intelligent supervision of urban gas PE pipeline network,we establish the physical and mathematical models of the network, study the leakage law, leakage detection method and sensitivity according to the intelligent PE valve node data. We use pipeline simulation software PipelineStudio to simulate the pipe network operation data, study the leakage law of pipeline network base on different operating conditions, detecte the leak by correlation analysis, and the leak location is made by pressure difference method, analyze the sensitivity of leak detection method base on a large number of simulation data.
