摘　　要：天然气管道环网沿线用户用气量经常变化,尤其将天然气作为调峰电厂的燃料时,管网系统会出现输气不均衡现象。利用管道储气技术.通过动态模拟计算方法可以调整和X上没计,解决系统供需矛盾,向用户安全、稳定供气。动态模拟方法是基于流体力学原理,用数学分析方法对输气管网系统运行参数进行描述,以调整和优化管网系统设计。结合工程实例,采用动态模拟方法计算了管网系统储气调峰能力,并对储气量进行了校核,所得结果符合调峰电厂的储气调峰要求。The amount of gas for consumers is extremely variable along the natural gas pipeline network. Therefore, non-equality for gas transmission will present in the network ,especially when natural gas is used as a fuel of the peak shaving power plant. With the technology of pipeline gas storage to resolve the contradiction of gas supply and demand as well as to safely and steadily supply gas to consumers,the method of transient dynamic simulation calculation of pipeline can be used to improve and optimize the pipeline network design. Dynamic simulating is used to expound the operating parameters of gas pipeline network by mathematical analysis method based on the principle of fluid mechanics to improve and optimize pipeline network design. Take a project design as an example,based on modulating and analyzing its calculated results ,the amount of gas storage of pipeline network has been checked up. It is pointed out that the dynamic simulation calculation will play a decisive role in the design of gas pipeline network with the function of gas storage and peak shaving.
