| 摘 要： | 实施LNG应急储备对于我国北方特大型城市应对极端寒冷天气导致的“气荒”具有重要意义，而储备设施的合理规模如何确定是值得探讨的一个重要问题。为此，通过将天然气管网时序负荷曲线转化为负荷持续曲线（将日负荷曲线按大小顺序重新排列得到），分析了冬季用气高峰时段的天然气管网负荷特性，利用数值拟合得到的5次多项式方程导出了冬季缺口气量计算式，进而解决了已有LNG应急储备与管网负荷的匹配问题以及规划阶段LNG应急储备规模的确定问题，为大型LNG储备设施的规划提供了依据。

| Abstract: | The preparation of LNG emergency storage reserves is of great significance to the alleviation of gas famine caused by ultra cold weather in many big cities of northern China.Then how to determine the reasonable capacity of LNG storage facilities is a problem worthy of discussion.In view of this,the load duration curves is first turned from the time-sequence load curves of a pipeline network,that is,the daily load curves are re-listed in a dimension order.On basis of this,the load features of this pipeline n... |
