| 摘 要： | 根据能量平衡原理,以各站的升压值作为决策变量,以全线的总动力费用为目标函数,建立了等温输油管道优化运行的数学模型;采用动态规划方法,利用管道进出站压头的约束条件,确定了各站的供给能量,进而获得全线各站升压值的最佳组合,制定运行优化方案。以大庆-锦西原油管道为例,对运行方案最优工况的确定方法和过程进行说明,并获得了经济合理的运行参数,可为制定管道运行优化方案提供技术支持。

| Abstract: | Using the boosting data as the decision-making variable for each pump station and the total power cost of the pipeline as the objective function,an optimized mathematical model for the oil pipeline operated at constant temperature was established based on the principle of energy balance.By means of dynamic programming,taking the inlet/outlet pressure heads of pipeline as the constraints to determine the provided energy to each pump station and furthermore to get a best combination for the boosting data for each pump station of the pipeline,the optimized operation program was successfully worked out.A case,Daqing-Jinxi Oil Pipeline,was researched to determine the optimized pipeline operation condition specifi ed in the running scheme and economic and rational running parameters were obtained.The research results can provide a technical support to the formulation of optimizing running scheme of oil pipeline. |
