| 摘 要： | 建立气体管道泄漏的仿真模型可以为基于模型的管道泄漏检测方法提供有效的测试信号,便于对算法的有效性进行正确的评价并对算法进行改进。根据管道系统与电路系统之间的相似性,提出采用一定结构的等效电路表达管道的泄漏,并从电路角度对管道末端的流动关系进行近似处理,实现对管道泄漏方程的求解,建立气体管道泄漏的仿真模型。并给出了仿真模型的实现方法和流程。仿真与现场泄漏测试结果的对比表明所建立的仿真模型具有较高的仿真精度。

| Abstract: | The simulation model of a leaking gas pipeline can generate test signals for model based leak detection and location methods and is helpful to validate and improve the algorithms.According to the similarity between the pipeline system and electric circuit system,a leak from gas pipeline can be simulated using an equivalent circuit with a certain structure.From the view of the circuit,the flow characteristics at the end of the pipeline has been dealt with some kind of approximation and therefore the equation... |
