成品油管道系统能否经济、高效地运行,关键在于运营单位编制与执行调度计划的水平。由于成品油管道是一个复杂的密闭水力系统,仅约束流量难以保证管道总体运行达到最优。当前,国内外学者针对成品油管道调度优化问题展开大量的研究,但少有研究将水力约束耦合在内。本文以调度周期内体积总偏差最小为目标函数,综合考虑了注入、分输、泵站、批次运移、水力等约束,建立了连续时间的混合整数非线性规划(MINLP)模型,并将其分解成整数规划(IP)问题及混合整数线性规划(MILP)问题求解。而后,利用提出的优化模型求解出某条成品油管道的具体优化调度方案和启泵方案。调度周期为179.7 h,计算时间180.32 s。调度计划满足现场需求,结果表明模型实用、高效。
Whether the oil product pipeline system can operate economically and efficiently lies in the level of the operating unit’s preparation and execution of the scheduling plan. As the product pipeline is a complex closed hydraulic system, it is difficult to ensure the optimal operation of the pipeline only by restricting the flow. At present, a great deal of research has been done by domestic and foreign scholars on the optimization of oil product pipelines, but few studies have coupled the hydraulic constraints. In this paper, the MINIMUM MINIMUM MINIMUM (MINIMUM) MINIMUM PROGRAMMING (MINLP) MODEL WITH CONTINUOUS TIME is established by taking the minimum total volume deviations as the objective function in the scheduling cycle. Considering the constraints of injection, transportation, pump station, It breaks down into integer programming (IP) problems and mixed integer linear programming (MILP) problems. Then, using the proposed optimization model to solve a specific product pipeline optimization scheduling and pump program. The scheduling period is 179.7 h and the calculation time is 180.32 s. Scheduling to meet the needs of the scene, the results show that the model is practical and efficient.
