- 对于长输热油密闭输油管道,当输量和油品性质-定时,寻求全线热站和泵站(热泵站)的升温、升压值的最佳组合以使全线的能耗费用最低,是长输热油管道运行方案优化的目标。文章结合盘锦输油管道实际,根据能量平衡原理,建立长输热油管道运行优化的数学模型,采用组合优化方法,利用计算机进行编程、计算,给出了运行方案的最优工况。方案实施结果表明,盘锦线运行总能耗降低32%。
For long-distance hot oil closed transmission pipeline, its operation scheme optimization objec-t1VC is to seek the optimal combination of increased temperatures and pressures at heating stations and pumpingstations of whole line under states of steady transmission volume and stable oil properties in order to minimizethe whole line energy consumption costs. Combined with the operation practice of Panjin Pipeline, the optimaloperation scheme is obtained through the following steps: establishing optimization mathematical model ofpipeline operation on the bases of energy balance theory, using combination optimization method, performingprogramming and calculation with a computer. The scheme implementation shows that the total energyconsumption of Panjin Pipeline operation reduces 32%.2010,2(2): 92-95 收稿日期：2009-10-26分类号：TE832.34作者简介：张维志(1958-)男，河北乐亭人，教授级高工，200年毕业于中国石油大学(北京)，硕士，现主要从事管道设计、研究及管理工作.
