摘要
通过对起伏地形天然气长输管道系统中影响管道和压缩机站运行费用的各种因素的分析,结合起伏地形的特殊性,以输气管道终值费用最小为目标函数,加以水力、热力、流态等约束条件,建立了起伏地形天然气长输管道优化运行数学模型,并利用惩罚函数法对模型进行求解。计算结果表明,该模型对实际工作具有指导作用。
An analysis is made to study the factors influencing operational cost of pipeline and compressor station in the long-distance natural gas transmission pipeline over hilly terrain. Combined with the characteristics of hilly natural gas transmission pipeline system and taken the minimum final cost of the pipeline as an objective function, with the restrictions such as the conditions of hydraulic, thermal condition and flow pattern,a mathematical model of optimal operation of such pipeline system is established and the model is solved with the penalty function method. Calculation result shows that the model is helpful for coaching the optimal operation of gas pipelines.
