- 摘要:
天然气长输管网构成了多环状结构的输气路径,管网公司将上游托运商的天然气运输到下游用户的路径有多种方式可供选择,从而对管网公司的利润产生较大的影响。针对管网中剩余能力不能满足托运商输送要求的问题,以管网公司利润最大为目标构建管输路径优化模型。考虑压气站、管道、节点平衡等约束条件,引入初始流量分配法对各条输气路径进行流量分配,通过优化算法对管网压力进行优化,得到管网公司在管网剩余能力不足下的托运方案。采用数学建模系统MATLAB调用遗传算法进行优化求解,算例验证了模型的准确性。优化结果表明,将管道剩余能力分配给管输平均运价率高的输气路径,可以增加管网公司收益,对提高运输商管输效益具有指导意义。
The long-distance natural gas pipeline network constitutes a gas transmission path with multi-ring structure. There are many ways for pipeline companies to choose the path of natural gas consignment from upstream suppliers to downstream users, which has a great impact on the profits of pipeline network companies. Aiming at the issue that the residual capacity of the pipeline network fails to meet the transmission requirements of the supplier, the pipeline transmission path optimization model is developed with the goal of maximizing the profit of the pipeline network companies. Considering the constraints such as pressure station, pipeline and node balance, the initial flow distribution method is introduced to allocate the flow of each gas transmission path. The pipeline pressure is optimized by the optimization algorithm, and the gas distribution scheme of the pipeline network company under insufficient residual capacity of the pipeline network is obtained. The mathematical modeling system MATLAB is used to call up the genetic algorithm for optimization, and the accuracy of the model is verified by a case study. The optimization results show that allocating the pipeline residual capacity to the gas transmission path with a high average transportation price can improve the income of pipeline companies, which is of guiding significance to improve the pipeline transmission profit margin of pipeline network operators.
