摘要
文中建立输气干线稳态运行优化的数学模型,并采用动态规划法进行求解。在求解的过程中,综合考虑计算速度和精度,建议离散步长选取20~40 k Pa。设计了天然气管道稳态运行优化软件—Opt NGP软件,采用TGNET软件和控制条件法分别对优化方案的合理性和最优性进行了验证,验证结果显示,Opt NGP软件能够为输气干线提供稳态最优运行方案。
Mathematical model of operating optimization under steady state in gas transmission trunk line was established which solved by dynamic programming method. When using the dynamic programming method,considering the speed and accuracy of the calculation,20 ~ 40 k Pa was recommended. Steady-state natural gas pipeline operation optimization software module Opt NGP was developed. The reasonableness of the optimization program and the optimal control condition of the optimization program was authenticated. The result show that the software Opt NGP can be used to optimize the calculation of the steady-state gas pipeline.
