At the same time, combining with the actual condition of delivery pipeline of our country and some prevalent leak detection and location methods, this paper raised a method, which is based on wavelet analysis and negative- pressure-wave to detect and locate the leakage. Jobs in the paper are as follows:As affected by gas density, pressure, specific heat and pipe material, the velocity of negative-pressure-wave improved depending on the energy conservation. At one time, taking the affection of velocity of gas flow, the location formula was modified in some degree.When locating the leaks with location formula, the iterative approach algorithm was adopted as a new method to increase the location accuracy level of system.Multi-scale decomposition and reconstruction of wavelet transform is utilized to filter the noise of negative-pressure-wave, which was brought by leakage. With the capacity to detect the signal singularity fast and accurately, wavelet transform was used to catch the break point of pressure signal. The work improved the accuracy of At in location formula, accordingly improved the location accuracy.Wavelet is a suitable tool for signal analysis. The distinct character is that the mother-wavelet is of optional. That means choosing different mother-wavelet will get different analysis result. So we studied how to choose mother-wavelet and its scale for signal singularity detection. The method is to choose a wavelet by regularities of the wavelet and the signal.Finally, a plan, which bases on SCADA system for inspection and detection of natural gas leakage, is proposed in the article.
其中,主要进行了以下几方面的工作:针对泄漏产生的负压波在管道中的传播速度受媒介的密度、压力、比热及材质等因素的影响,而非声波在空气中传播的速度,本文利用能量守恒原理,对其进行了修正;考虑到管内气体流速对压力波速的影响,对原始的负压波定位公式进行了一定程度的改进,并在利用定位公式进行泄漏点定位时采用逐步迭代逼近算法,提高了系统的定位精度;利用小波变换的多分辨率分解和重构技术,对采集到的管道发生泄漏时产生的负压波信号进行了降噪处理;并利用小波变换技术对信号奇异点的快速、准确的识别能力,对经上述消噪后的负压波信号进行了奇异点捕捉,精确捕捉的结果提高了定位公式中上下游站点采集到的负压波奇异点的时间差△t的精度,从而进一步提高了定位的精度;考虑到小波变换是一种基波可变的信号分析工具,也就是说,不同的小波基波对信号分析的结果将有很大差别,这势必影响最终的处理结果,因此,我们又对比分析了本课题中小波基及尺度的选择问题,依据规则性系数相似性原理对母小波的选择进行了探索性研究;最后,还提出了基于SCADA的泄漏检测与定位系统的软件开发构想及系统的嵌入方案。
