输配气管网稳态仿真问题的拓广

Widened steady state simulation of gas distribution networks

采用节点法建立了输配气管网稳态仿真的数学模型,并提出了求解模型的有效算法。文献中的输配气管网稳态仿真问题局限于每个节点必须给出一个已知参数,该文中将这类问题推广到更一般的情况,从而使输配气管网稳态仿真的适用性和灵活性更强。实例计算结果表明,该模型的计算稳定性和收敛性均较好,计算结果与预测结果相吻合。

The steady state simulation mathematical model of gas distribution networks was established using the nodal analysis method, and the effective algorithm to solve the model was given. In consideration of the pattern of every node that must be given a known parameter in steady state simulation of gas distribution networks, the problen of steady state simulation was widened, which can make the steady state simulation more widdy used. The calculation example slows that the mathematical model has a good stability of calculation and convergence property. The calculation results agree well with the prediction ones.
