输气管道末段储气能力计算

摘要

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.%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 ease example and calculating results, storage capacity of end section was figured out.
