摘要
天然气在管道系统中流动时,需要依靠压缩机组提供能量,压缩机组的能耗很大,一般可占所输送天然气的3%~5%,因此非常有必要研究输气管道的优化运行问题。本文论述了输气管道系统非稳态优化运行技术的研究现状及发展趋势,总结了国内外研究的典型输气管道非稳态优化运行问题以及采用的数学模型,包括决策变量、目标函数和约束条件等。分析了输气管道非稳态优化运行数学模型的求解难点、主要算法、典型算例及其应用效果。
When the gas flows through the pipeline, compressors are used to compensate the pressure loss due to the friction by consuming the fuel gas. For the fuel gas used by compressors constitutes a significant part （about 3%-5% of the gas running through the pipeline）, it is quite necessary to study how to optimize the operation of the gas pipeline in a better way that the consumer＇s demands are satisfied and the compressors are set cost-efficiently. The paper summarizes related typical transient operation issues. The mathematical model for optimizing the gas pipeline operation in a transient flow is built, and the commonly used algorithms and the relevant results are analyzed in detail.
