摘要:: 面向国家石油天然气管网集团有限公司（简称国家管网集团）大规模复杂天然气管网的仿真应用需求及管道行业智能化转型的实际需要，提出了一种全新的仿真引擎核心算法——分区增量迭代法，攻关完成了具备先进性、健壮性、开放性的工业级天然气管网仿真引擎，基于总体架构和应用架构设计，完成了离线仿真软件的开发，实现了大型复杂天然气管网仿真核心技术自主可控。依托开发的天然气管网离线仿真软件，对某新建管道完成了设计校核，平均相对误差为0.1%；以全要素涩宁兰管道为对象建模，并与商业软件结果进行对比发现，管道沿线各站的压力、流量在稳态与瞬态仿真下的最大相对误差均小于1%；针对大规模、复杂拓扑结构的2×10⁴ km级全要素天然气工业管网，该离线仿真软件对其具备仿真能力。所开发天然气管网离线仿真软件能够满足未来“全国一张网”的仿真需求，可为国家管网集团的数字化战略及智能化转型提供专业化仿真服务。

Abstract:: Facing the simulation application requirements of large complex natural gas pipeline networks of China Oil & Gas Pipeline Network Corporation (hereinafter referred to as PipeChina) and the actual need for intelligent transformation of the pipeline industry, a new core simulation engine algorithm, i.e. zoning incremental/iterative method, was proposed. On this basis, the industrial simulation engine of the natural gas pipeline network with progressiveness, robustness and openness was completed. Then, the offline simulation software was developed based on the overall architecture and the application architecture design, realizing the autonomous control over the core simulation technology of large complex natural gas pipeline networks. Using the developed offline simulation software for natural gas pipeline networks, design verification was completed for a newly built pipeline, with an average relative error of 0.1%. By modeling based on the all-element Se‒Ning‒Lan Pipeline and comparing with the results of commercial software, the maximum relative error of pressure and flow of stations along the pipeline is less than 1% in the steady-state and transient simulation. Besides, the offline simulation software is capable of simulating the all-element natural gas pipeline networks at 2 × 104 km level with a large complex topological structure. Generally, the developed offline simulation software of natural gas pipeline networks could meet the simulation needs of the unified national network in the future, providing professional simulation service for the digital strategy and intelligent transformation of PipeChina.
