摘要
为了解决输气管道仿真系统存在计算值与实际值偏差的问题,对解决该问题的模型校正技术展开国内外调研。提出造成仿真计算不精准的三个主要误差来源:输入参数测量误差、缓变参数误差、手工输入误差。最后通过分析国内外仿真模型校正技术研究现状,建议在动态仿真的基础开展输气管道的模型校正技术研究,以避免输气管道系统数据波动带来的误差。
Aiming at the problem of the deviation between the calculated value and the actual value of the gas pipeline simulation system, this paper conducts domestic and foreign investigations on the model correction technology to solve this problem, and proposes three main sources of error that cause inaccurate simulation calculation: input parameter measurement error, slowly changing parameter error, manual input error. Finally, by analyzing the current research status of simulation model correction technology at home and abroad, it is recommended to carry out research on model correction technology of gas pipelines based on dynamic simulation to avoid errors caused by data fluctuations in gas pipeline systems.
