摘    要:将序贯概率比检测法(SPRT)应用到管道泄漏的在线故障诊断中,基于SPRT检测法提出了泄漏识别因子,该因子的提出大大提高了泄漏监测系统的识别精度。同时对于非稳定流体,引入了相对稳定过程的概念,通过对均衡流量的检验可以进行泄漏监测。最后,利用参数识别等方法对泄漏进行定位,实验结果证明了方法的有效性。

关 键 词:长输管道  泄漏故障  诊断方法  序贯概率比检验法  参数识别

Abstract:A new pipeline leakage detection system based on the Sequential probability Ratio Test (SPRT) is presented in this paper. This detection system may apply SPRT test to the flow and pressure measurements at the ends of a pipeline. In order to improve the identical accuracy of this detection system, a leakage recognition factor is proposed. By mean of monitoring the difference of the outlet and inlet flow, this detection system has successfully identified the leakage for the non stationary flow. Finally, the leakage of the system can been located via parameter identifications.
Keywords:Sequential probability Ratio Test (SPRT)  leakage  monitoring  locate
