| 中文摘要 | 在输油管道泄漏监测中,站上扰动所导致的频繁误报会严重影响用户对系统的信心。为降低站上扰动带来的泄漏误报,提出了一种基于统计建模和小波变换的泄漏监测系统抗扰动算法。该算法利用模型残差在泄漏和站上扰动两种情况下的差异,使用小波变换的方法将二者区分开来,从而有效地排除了站上扰动带来的误报。基于某实际管线的历史数据的离线测试表明,同该管道中实际运行的监测系统相比,该算法可以使三个月的误报次数从16次降低到5次。; In leak detection of oil pipelines,false alarms caused by normal operations at the station may badly reduce the user confidence in leak detection systems.An efficient algorithm is proposed based on statistical modeling and wavelet transform to reduce this kind of false alarm.Based on the great difference in model residual between leak and operation,the algorithm distinguishes operation from leak by using the result of wavelet transform.Offline test results based on a set of data of three months show that,compared with the old leak detection system running at a real pipeline,the new method can reduce the total number of false alarm from 16 to 5. |
