摘　　要：天然气管输计划的编制主要依赖人工经验,编制过程需要花费大量的时间、精力,不利于管输计划的整体优化。为提高天然气管输计划编制的效率和科学性,通过对现有编制方法进行梳理,将编制天然气管输计划的人工经验编码化,开发了一种管输计划辅助编制软件以寻找可行解。在天然气管网进销平衡、设计输量等约束条件下,以天然气管网能耗最低为优化目标,通过对大量能耗、输量历史数据进行统计、拟合分析,建立了天然气管网优化模型,利用最优化方法寻求最优可行解,并以两条干线管道为例,阐述了生产单耗与周转量拟合过程。研究结果可为复杂的天然气管网系统提供一种高效、科学的管输计划优化编制方法。At present, the natural gas pipeline transportation plan is mainly prepared based on the artificial experience, which requires considerable time and energy, unfavourable for the overall optimization of the plan. In order to enhance the preparation efficiency and scientificity of the natural gas pipeline transportation plan, the artificial experience for preparation of the natural gas pipeline transportation plan was encoded by summarizing the existing preparation methods, and auxiliary software was developed to seek a feasible solution for the pipeline transportation plan. With the constraints of supply and sales balance and the design throughput of the natural gas pipeline network, and with the minimum energy consumption of the gas pipeline network as the optimization target, a natural gas pipeline network optimization model was established based on the statistical and fitting analysis on the massive historical data of energy consumption and throughput, and the optimal feasible solution was sought with the optimization method. Furthermore, the fitting process between unit consumption and turnover volume was elaborated by taking two trunk lines as the examples. The new optimization method could provide an efficient and scientific optimized preparation method of pipeline transportation plan for complex natural gas pipeline network system.
