【摘要】：針對鋼鐵企業(yè)高爐休風(fēng)場景下的氧氣生產(chǎn)調(diào)度問題,提出以空分短期計劃性停車為主要手段的調(diào)度策略,并基于MILP方法建立了氧氣系統(tǒng)的優(yōu)化調(diào)度模型。調(diào)度模型的優(yōu)化目標為整個規(guī)劃周期內(nèi)氧氣高壓管網(wǎng)的綜合壓力最小化。模型包含了空分和部分氧氣壓縮機短期停車再啟動操作的約束條件,并結(jié)合實際情況考慮了前述設(shè)備的停車時間閾值和運行時間閾值。以國內(nèi)某大型鋼鐵企業(yè)為實際案例,驗證了調(diào)度模型的合理性與可行性,然后基于模型計算分析了空分停車時間閾值對調(diào)度目標的影響規(guī)律。分析結(jié)果表明,減小空分停車時間閾值有利于獲得更優(yōu)的調(diào)度目標,但空分停車時間閾值對優(yōu)化目標的影響規(guī)律具有階躍特性,而非簡單的比例關(guān)系。
[Abstract]:In order to solve the problem of oxygen production scheduling in blast furnace of iron and steel enterprises, a scheduling strategy based on short term scheduled parking of air separation is proposed, and the optimal scheduling model of oxygen system is established based on MILP method. The optimization goal of the scheduling model is to minimize the integrated pressure of the oxygen high pressure pipe network throughout the planning period. The model includes the constraints of air separation and partial oxygen compressor short-term shutdown restart operation and considers the shutdown time threshold and the operating time threshold of the said equipment according to the actual situation. The rationality and feasibility of the scheduling model are verified by taking a large iron and steel enterprise in China as a practical case. Based on the calculation of the model, the influence law of the threshold of the air-separated stop time on the scheduling target is analyzed. The results show that reducing the threshold of stop time in air separation is beneficial to the optimal scheduling target, but the law of the effect of stop time threshold of air separation on the optimal target has a step characteristic rather than a simple proportional relationship.
