在天然气供求矛盾日益加剧的情况下，通过研究四川盆地天然气管输供气负荷特征与用户用气负荷特征及气价的关系，提出在一定输气设施所确定的管输能力情况下，通过移峰填谷和择优配置负荷，既可以提高天然气管输供、用气设施效率，缓解一部分天然气供求矛盾，又可提高天然气销售效益。文中提出的供用气负荷系数优化模型和天然气供用负荷优化模型可为制定天然气销售计划提供参考依据。提出用天然气管输供用气负荷系数来度量天然气管输的供用气负荷特征，对一般天然气管道项目的工程设计、管输费制订、经营管理等都有重要参考意义。

Optimization Study of Gas Supplying/Delivering Loads of Gas Pipelines

Under the situation of gas supply/demand contradiction growing day after day, by studying the features of gas supplying/delivering loads of gas pipelines and the gas price in the Sichuan basin, according to the gas transmission capacity of the pipelines limited by the given gas transmission facilities, it is suggested removing the peak to fill the valley and optimal distributing the loads, which can not only improve the efficiency of gas supplying/delivering facilities, and release a part of gas supply/demand contradiction, but also improve the benefit of gas marketing. The optimization model of gas supplying/delivering load coefficients and the optimization model of gas supplying/delivering loads proposed in the article can provide the reference to make the gas-marketing plan. It is suggested the gas supplying/delivering load coefficients are used to measure the gas supplying/delivering load features, which has important guiding significance for the engineering design, the gas transmission price making, operation and management etc. of gas pipelines.
