| 摘 要： | 针对Line-Pack模型无法考察天然气系统内部不同规模管道的动态特性问题,在分析输气管道压力与质量流动态平衡过程差异性的基础上,将输气管道分解为有限多个小规模等长管元,在每个管元上计及压力与质量流平衡时间差,将天然气在输气管道内的复杂运动过程近似等效为有限个管元的气体稳定运动,构建了计及气网多规模长输气管道的改进Line-Pack模型以融入优化调度模型,并给出了线性化处理方案以便于适应大规模问题求解。基于修改的比利时20节点天然气系统和IEEE 39节点电力系统构建了算例系统,采用Pipeline Studio商业油气仿真软件对所提模型计算得到的调度方案进行分析,验证了所提改进模型的合理性和有效性。

| Abstract: | Based on the analysis of the difference between the pressure and mass flow dynamic balance processes of the gas pipeline, the gas pipeline was decomposed into a limited number of small-scale equal lengths. The tube element, on each tube element, applied an improved Line-Pack model that took into account the time difference between pressure and mass flow balance, and approximated the complex motion of natural gas in the gas pipeline to a gas-stable motion of a limited number of tubes. The improved Line-Pack model, which took into account the multi-scale long gas pipelines of gas networks, was incorporated into the optimal scheduling model as a constraint, and a linearization scheme was proposed to adapt to large-scale problem solving. The modified Belgian 20-node natural gas system and IEEE 39-node power system were used in the example. Pipeline Studio commercial oil and gas simulation software was used to simulate the scheduling scheme calculated by the proposed model, and the rationality and effectiveness of the proposed improved model were verified. |
