摘要
管道泄漏检测技术已经在长输气体管道安全运行中起到很重要的作用。本文讨论了基于李雅普诺夫稳定性理论的天然气管道泄漏检测技术,建立了气体管道泄漏动态模型,根据李雅普诺夫意义下对非线性系统的稳定性定义,通过对特征值的分析判断泄漏。实验仿真证明该方法具有一定的可行性。
The detection technology of leakage in gas pipeline has played very important role in long gas pipeline security.This paper discussed the detection technology of leakage in gas pipeline based on the Lyapunov stability criteria.A new leak model in gas pipeline is presented.According to the definition of Lyapunov stability point to nonlinear system.a leak is determined through analyzing the eigenval ues.The simulation experiment has proved the feasibility.
