管道末段储气调峰分析方法

在复杂输气管道稳定过程分析方法的基础上,建立了输气管道储气能力分析方法.该方法可以根据管道起点或终点的压力限制条件和稳态输量,确定管道末段储气调峰的能力和用储气库参与小时调峰的需求,能够系统地分析复杂输气管网工艺过程,确定管道末段储气调峰能力,是一种简便、实用的近似方法.在瞬态分析前,可对管网系统末段储气调峰能力进行预测和判断.经计算比较,提出的方法与SPS系统分析结果吻合很好,可用于预测管道的储气能力.在实际应用中,特别是在管道可行性研究和设计阶段具有重要的价值.

The Analysis Method on the End Section of Storage Capacity of Gas Pipeline

On the base of established steady analysis method of complicated gas pipeline,the analysis method of storage capacity of gas transmission pipeline is established. According to pressure constraints of the start and end point and steady flux,this method can determine gas storage capacity in the end section of pipeline and the demand of hour peak shaving with underground natural gas storage. This method,which is convenient and practical,can analyze the process of complex gas pipeline network, determine the capacity of gas storage and peak shaving and forecast and judge the capacity of gas storage and peak shaving before the transient analysis as well. Results of this method agreed well with those of SPS system. It can be applied in predicting the storage capacity and is of importance in practical application,specially in the stage of feasibility study and design of gas pipeline.
