随着国际原油价格的日趋增高,如何节约能源、提高效益已成为迫在眉睫的问题。本文以原油管道运输中加热炉机组为研究对象,分析研究了各机组间负荷的优化分配。结果表明:在加热炉机组确定的情况下,并联机组间的负荷分配适用等微增率原则。等微增率原则再加上Kuhn-Tucker最优性条件后能够解决加热炉机组间负荷经济分配问题。 With the international crude oil prices increasing, how to save energy and improve efficiency has become an urgent issue. In this paper, the heating unit of crude oil pipeline transportation is taken as the research object, the optimal distribution of loads among various units is analyzed and studied. The results show that under the condition of determining the heating furnace unit, the load sharing among parallel units applies the principle of micro increasing rate. The principle of such micro-increment coupled with Kuhn-Tucker optimality conditions can solve the problem of economic distribution of load among heating units.
