【摘要】：在输送计划一定的情况下合理制定成品油管道沿线各个泵站的开泵方案,可以确保成品油管道安全、经济地运行。在对成品油管道顺序输送问题深入分析的基础上,以沿线泵站动力费用总和最少为目标函数,建立成品油管道调度的优化开泵方案数学模型,模型采用离散时间表达。采用蚁群算法与动态规划算法混合求解模型,以西南成品油管道为例进行模拟计算,并将两种算法混合求解的计算结果与采用动态规划算法和遗传算法单独求解结果进行对比。结果表明:输油计划中的关键时刻采用动态规划算法求解,非关键时刻采用蚁群算法求解。相比于前人所采用的算法,在保证所求开泵方案经济性的基础上,大幅度提高了求解计算效率,从而确保大型成品油管道稳定、高效地运行,符合现场工艺要求。
[Abstract]:In the case of certain transportation plan, it can ensure the safe and economical operation of the finished oil pipeline by rationally formulating the pump opening scheme of each pumping station along the product pipeline. On the basis of the in-depth analysis of the sequential transportation problem of the finished oil pipeline, Taking the minimum sum of power cost of pumping stations along the line as the objective function, the mathematical model of optimal pump opening scheme for oil pipeline scheduling is established. The model is expressed in discrete time, and the ant colony algorithm and dynamic programming algorithm are used to solve the model. Taking the Southwest Oil Product Pipeline as an example, The results of the mixed solution of the two algorithms are compared with the results of the dynamic programming algorithm and the genetic algorithm. The results show that the dynamic programming algorithm is used to solve the key points in the oil transportation plan. Ant colony algorithm is used to solve the problem at non-critical time. Compared with the previous algorithm, the efficiency of solving the problem is greatly improved on the basis of ensuring the economy of the pump opening scheme, thus ensuring the stable and efficient operation of the large oil product pipeline. Meet the site process requirements.
