在建立符合实际工况的多气源组分平衡计算模型的基础上,以处理厂原料气气质指标为目标函数,建立优化模型并求解,得到在满足管网运行约束及各处理厂原料气气质指标前提下的管网运行参数。实例应用表明,建立的集输管网优化调度模型既可体现各气源点气质的差异性,又能满足各天然气处理厂对原料气气质的不同要求,计算结果能够准确地反映管网中的气质状况,从而确保净化装置的平稳运行。将该模型应用于实际管网,可为其生产运行调度提供重要的参考依据。
Based on the establishment of the balance calculation model of multi-gas source components in line with the actual working conditions, taking the gas quality indicators of the feed gas of the treatment plant as the objective function, an optimization model is established and solved, and the gas- Indicators under the premise of pipe network operating parameters. The example application shows that the optimal scheduling model of the set of transmission and distribution network can not only reflect the difference of the temperament of each gas source, but also meet the different requirements of the gas processing plants for the quality of the raw gas. The calculation results can accurately reflect the differences Temperament, thus ensuring the smooth operation of the purification device. Applying this model to the actual pipe network can provide an important reference for its production and operation scheduling.
