摘要
对于具有多泵(减压)站的输油管道,在给定输送油品状况和热力状况的条件下,各管段的水力坡降线随之确定,管道的动力费用仅与各站的增压或减压值有关。为确定全线各站的进、出站压力,建立以动力费用作为目标函数,以管道的承压能力和允许最小压力作为约束条件的优化模型。而后将其转化为各站相对独立的以进站压力作为目标函数的优化模型,并提出了求解该模型的水力坡降线平移方法。该方法计算简便,易于编程,特别适合于成品油管道,并已应用于兰成渝成品油管道的运行调度系统。
For the oil pipeline with multiple pump stations, given that the thermal state and transportation plan of oil pipeline are specified, the hydraulic grade line of the pipeline can be fixed with it whereas the pipeline's power consumption is only related to the pressurization or the decompression of the stations. In order to determine the inlet and outlet pressures of pump stations or of pressure reducing stations of the whole pipeline, the optimization model was established by using power consumption as objective function and the pipeline's pressure bearing capacity and permitted minimum pressure as constraint conditions. The model then was transformed into the station-separated optimization model, which used inlet pressure as objective function. Thus, a new method, translating hydraulic grade line method, used to work out the station-separated optimization model was put forward. The method is simple and convenient, easy to program, and especially suitable for products pipeline. It has found the application in production management of Lanzhou-Chengdu-Chongqing products pipeline.
