摘　　要：如何提高蒸汽系统整体的运行效率,减少蒸汽的放散损失,对于钢铁企业的节能减排、降低吨钢成本意义重大。针对蒸汽系统中不同类型的汽源设备运行方式差别较大的特点,以某大型钢铁企业蒸汽系统的实际运行为背景,建立了多汽源、多用户、多产品、分时的动态配置线性规划模型。该模型将不同汽源设备组成的系统作为一个整体进行研究,以更实际更直观的蒸汽发电量最大为目标,并利用约束从客观上保证了余热汽源的充分利用。最后根据现场数据,利用CPLEX得到了最优解。How to imorove the operating efficiency of whole steam system and reduce the steam diffuion loss are of great significance so as to save energy, reduce emission and reduce the cost of per ton iron. This paper develops a time sharing dynamic linear programming model with multi-steam-source, multi-customer and muhi-product by considering the operating differences of various steam source equipments in the steam system and using a real operation of steam system in an iron ＆ steel enterprise as background. The model con- siders the combined system of different steam source facilities as a whole system. A practical and direct object of maximizing the steam electriciy generation is adopted, and the full use of the residual steam sources is guaranteed by constraint conditions. Finally, CPLEX is adopted to obtain the optimal solution based on the on-the-spot data.
