摘　　要：管道储气调峰方式有许多种。其中,末段储气调峰是非常重要的一种调峰方式。目前,工程上经常使用稳态计算方法对末段储气量进行估算,但是由于管道储气过程的复杂性,以及工业用户间歇性用气,稳态结果往往存在偏差。针对某实例管道,分别进行了管道末段储气能力稳态计算与动态计算,结果表明,动态模拟下管道储气量最大时刻滞后于稳态模拟,储气量也大于稳态模拟。The method of gas storage and peak shaving of gas pipeline is various. Gas storage and peak shaving in end section is one of these methods. At present, the steady-state simulation is often used to estimate gas storage capacity of the end section in the engineering. But there is a deviation in the results of the steady-state simulation because of the complexity of the pipeline gas storage process and the intermittency of using gas. In this paper, steady-state calculation and dynamic calculation were performed for the gas storage in end section of gas pipeline. The results show that the time of the maximum gas storage capacity obtained by the dynamic simulation lags behind that obtained by the steady-state simulation, and the gas storage capacity obtained by the dynamic simulation is greater than that obtained by the steady-state simulation.
