- 摘要:
纯氢与掺氢天然气管网稳态仿真软件是一款基于B/S架构的稳态仿真软件(以下简称稳态仿真),适用于天然气管道、掺氢天然气管道和纯氢管道。详细介绍软件的数学模型和求解方法,并通过物性参数计算案例、天然气管网仿真案例、掺氢天然气环道实验案例、纯氢实际运行管道案例,验证软件的仿真精度。结果表明,针对天然气管网仿真案例,本软件与SPS软件全线压力的平均相对误差为1.08%,全线温度的平均相对误差为0.89%,表明本软件有大型天然气枝状管网稳态仿真的能力;针对掺氢天然气环道实验案例,相较于SPS软件,本软件压降的平均相对误差低了40.98%;针对纯氢实际管道运行案例,本软件压降和温降的误差分别降低了53.85%和36.58%。研究结果对纯氢与掺氢天然气管道的工艺设计和运行安全具有指导意义。
The steady-state simulation software(steady-state simulation) for pure hydrogen and hydrogen-blended natural gas pipeline networks is developed based on a B/S architecture and is applicable to natural gas pipelines, hydrogen-blended natural gas pipelines, and pure hydrogen pipelines. The mathematical model and solution method of the software are introduced in detail, and the simulation accuracy of the software is verified through case studies, including thermophysical property calculations, natural gas pipeline simulations, hydrogen-blended natural gas loop experiments, and pure hydrogen operational pipeline cases. The results show that, for the natural gas pipeline simulation case, the average relative error of pipeline-wide pressure compared to SPS software is 1.08%, and the average relative error of temperature is 0.89%, indicating that this software is capable of steady-state simulation of large-scale branched natural gas pipeline networks. For the hydrogen-blended natural gas loop experiment case, the average relative error of pressure drop of this software is 40.98% lower than that of SPS software. For the actual operational case of a pure hydrogen pipeline, the errors of pressure drop and temperature drop are reduced by 53.85% and 36.58%, respectively. The results has guiding significance for the process design and operational safety of pure hydrogen and hydrogen-blended natural gas pipelines.
