摘要
在天然气管网的建设过程中,由于要兼顾技术性与经济性两个重要因素,因此需要在众多可行方案中做出最优选择。重点介绍了天然气管网参数优化的原则,以投资运行费用最小为目标建立目标函数,并在满足管道强度、稳定性、气体流动性以及节点流量的约束条件下进行运算。介绍了常用的复合型算法、罚函数算法以及遗传算法,将多种算法相结合可以简化对优化数学模型的运算。
In the construction of natural gas pipe network, due to consideration of two important factors of technology and economy, so we need to make the best choice among these feasible schemes. In this paper, the principle of parameters optimization of natural gas pipeline network was introduced. The objective function for minimizing the investment and running cost was established, then it was solved under the premise to meet the pipeline strength, stability, gas flow and node flow conditions. The complex algorithm, penalty function method and genetic algorithm were introduced, and these algorithms were combined to simplify the calculation of the optimization mathematical model.
