Algorithmic Method based on Gas Transmission Pipeline Network Steady-state Operation Optimization

应用油气管道输送理论和最优化技术对管网系统的稳态运行进行了分析,建立了基于压缩机站的最小能耗费用数学模型,对管网的拓扑结构进行分解简化后,在动态规划算法的基础上结合网络最小费用流理论对其进行求解。结果表明,该计算方法对树形、环形管网均适用,而且优化效果好于一般的方法。

Taking the high fuel cost for operation of gas transmission pipeline network system into account,this paper applies oil and gas pipeline transmission theory and optimization technique to analyze the steady-state operation of pipeline network system,sets up a mathematical model of minimum fuel cost based on compressor station,reduces topological structure of pipeline network,uses dynamic programming and minimum cost flow to solve optimized model.The conclusion recommends that the algorithmic method is not only applied to the tree pipeline network system,but also to the loop pipeline network system,and the optimization effect is better than other methods.
