摘要: 天然气输配系统通常是由不同压力范围的管道组成的高度密集的网络系统.在管道系统的规划和设计过程中,为了保证其安全、经济性,对管道系统进行模拟和分析是十分重要的.针对复杂输气管道系统的特征,采用系统分析的观点,将管道系统划分成一定的子系统,并通过建立子系统中不稳定流动的数学模型和综合相关的连接条件、边界条件和初始条件,提出了整个管道系统的联立模型,然后利用泛函分析理论和算子级数法求解联立模型,得到了问题的广义解.该模型和求解方法已编成计算机程序,已应用于四川输气管道的模拟.通过分析和应用表明,其模型和算法具有计算方便,精度高,省时和适用范围广等优点.

Abstract: A lot of gas transportation and distribution systems consist of a large set of highly integrated safe and economic pipe networks with a wide range of pressure.Simulation and analysis play a major role in system planning and designing.In the light of system characteristics of complex gas pipeline,this paper presents a realistic transient flow model consisting of simple models of pipeline subsystems and connecting conditions,boundary conditions and initial condition associated with subsystems by using system analysis method.The solutions in wide sense are obtained by theory of functional analysis and operator series method.A ge neral computer program has been developed for this model and solutions have been used successfully in a local natural gas transmission network in Sichuan.It is proved that the model and algorithm proposed in this paper are of the advantages of convenient calculation,high precision,saving time and wide applied range by way of analysis and application.
