摘要
输油管道在现代社会中的应用越来越广泛,但是随着管道运行时间的延长,由于各种原因导致的管道泄漏将造成资源的浪费和环境污染,建立管道泄漏检测系统,及时准确地报告事故的范围和程度,可以最大限度地减少经济损失和环境污染。文章总结了国内外近几十年来发展起来的管道泄漏检测和定位的主要方法,重点介绍了基于现代控制理论和信号处理的方法,分析了各种管道泄漏检测方法的原理及优缺点,并探讨了管道泄漏检测的发展趋势。指出采用软硬件结合的方法进行输油管道泄漏检测、泄漏检测系统与SCADA结合、将分布式光纤传感器应用于管道泄漏检测中将有良好的发展前景。
The domestic and international major methods for leak detection technology for petroleum pipeline developed in resent years have been summarized. As focal point, the methods based on modern control theory and signal handling have been introduced. The principles, advantages and shortcomings have been analyzed for various methods. The development tendency has been discussed. It has good development prospect to carry out the methods that combine with software hardware, leak detection system and SCADA, apply the sensor of optical cable of distribution type in pipeline to leak detection.
