秦京输油管道优化运行研究

Study on optimization operation of Qinjing Oil Transport Pipeline

在对秦京输油管道系统分析的基础上,建立了秦京输油管道优化运行的动态规划数学模型,将这个数学模型看作二维资源分配问题,即把全线总压头和全线总热负荷在各站间进行最优分配。提出了一种二维动态规划求解方法,在求解时用逐次逼近法降维。这种方法既充分考虑了秦京输油管道的特点,又兼顾了数学上的严密性。在所建立的数学模型及提出的优化计算方法的基础上,用Windows环境下Visual Basic语言开发了秦京输油管道优化运行软件。

Establishes a mathematics model of dynamic planning on optimization operation of Qingjing oil Pipeline based on an analysis of this pipeline system, and regards this model as a two-dimensional resource distribution method, that is to make optimum distribution of entire pipeline heads and total thermal loads to each station. Puts forward a solution finding method of two-dimensional dynamic planning, using step-by step procedure to reduce dimension in solution finding. This method not only takes characteristics of Qingjing Oil Pipeline into fully account, but also gives consideration to mathematical tightness. Based on the mathematics model established and the optimum calculation method put forward, an optimized operational software of Qingjing Oil Pipeline is developed using Visual Basic Language under Windows environment.
