输气管道末段储气能力计算

输气管道末段储气是最经济的短期调峰方式,末段储气能力的计算能为天然气管道供气系统的规划、设计和运行管理提供理论指导。在合理的假设基础上,建立了较真实反映输气管内气体等温流动的方程组,并采用混合TVD方法求解该方程组,结合计算机编程,对输气管道末段的流量和压力等参数进行模拟。通过分析模拟数据,进而计算出输气管道末段储气能力,并通过算例加以说明。

Calculating storage capacity of end section of a gas transmission line

end section storage is the most economic method of a short-term peak shaving for a gas transmission line.Calculating its storage capacity can be useful to planning,design and operation of a gas pipeline.Based on several reasonable hypotheses,an equation set was established to describe a real isothermal flow of gas in pipeline and solved by mixed TVD scheme.Some parameters such as flow rate and pressure in end section of a gas line was simulated that by programming.According to a case example and calculating...
