摘要: 针对热油管道运行费用问题进行了分析。指出求解目标函数能耗费用最小值时, 应同时将输油泵组效率和加热设备系统效率作为决策变量; 对给定流量的优化问题改为某一小流量范围内的优化问题; 利用计算机数据采集控制系统对试验结果进行费用反馈验证, 找出偏差并制定新的方案, 目的是将输油单耗真正控制在最小范围之内。Abstract: This paper analyzes the operation cost problem of hot oil pipeline. It is pointe d out that the efficiency of pump set and heating system should be taken as a decision variables when the minimum value of energy consumption cost of objective function is calculated; the optimal problem of giv en flow rate should be changed to that of a small flow rate in scope; the operation cost obtained by exp eriment results should be identified on a feedback base with computer data acquisition system to find out deviation and work out new scenario, aiming to control the transportation cost in a minimum scope.
