【摘要】：由于輸油管線距離長(zhǎng)、工況復(fù)雜的特點(diǎn),僅靠人工巡線來監(jiān)測(cè)泄漏是遠(yuǎn)遠(yuǎn)不夠的,單一的管道泄漏檢測(cè)方法很難達(dá)到精確地預(yù)報(bào)警及泄漏點(diǎn)的定位,迄今為止對(duì)輸油管道泄漏進(jìn)行實(shí)時(shí)監(jiān)測(cè)的系統(tǒng)已有大量研究及應(yīng)用,但都存在不足無法達(dá)到完美,所以,對(duì)于輸油管道泄漏實(shí)時(shí)監(jiān)測(cè)系統(tǒng)的研究仍存在一定改進(jìn)空間及研究?jī)r(jià)值。本文簡(jiǎn)要介紹了我們國家的管道目前的狀況以及國內(nèi)、國外管道的泄漏檢測(cè)技術(shù)發(fā)展情況,并對(duì)目前常用的輸油管道檢漏與泄漏點(diǎn)定位的幾種方法進(jìn)行了對(duì)比分析,并以負(fù)壓波理論為基礎(chǔ),研究了與SCADA系統(tǒng)(數(shù)據(jù)采集與監(jiān)控系統(tǒng))相結(jié)合的輸油管道泄漏實(shí)時(shí)監(jiān)測(cè)系統(tǒng),其實(shí)際應(yīng)用到沈—興輸油管道,并取得較好應(yīng)用效果。SCADA系統(tǒng)主要采用輸差檢漏法和負(fù)壓波理論結(jié)合的方法進(jìn)行管道泄漏監(jiān)測(cè)與泄漏點(diǎn)定位,利用負(fù)壓波方法進(jìn)行管道泄漏檢測(cè),需要確定其傳播速度,同時(shí)考慮位于管道兩端的壓力變送器的響應(yīng)時(shí)間差以及克服噪聲的影響,本文采用全球定位GPS系統(tǒng)校正管道首末端計(jì)算機(jī)系統(tǒng)的時(shí)間以實(shí)現(xiàn)時(shí)間上的統(tǒng)一,采用信號(hào)處理方法提高管道檢漏及泄漏點(diǎn)定位精度,采用離散小波變換的方法用以提取瞬態(tài)壓力波信號(hào)邊沿,以完成準(zhǔn)確從工業(yè)現(xiàn)場(chǎng)的電磁干擾等噪聲干擾中將信息的特征點(diǎn)分離出來,小波變換采用濾波器組方法進(jìn)行計(jì)算。研究的該泄漏監(jiān)測(cè)系統(tǒng)以期為管道泄漏實(shí)時(shí)監(jiān)測(cè)領(lǐng)域提供新的思路和方法,在國內(nèi)處于較高水平,在輸油管道的實(shí)時(shí)泄漏檢測(cè)與定位方面具有較高的應(yīng)用價(jià)值。但系統(tǒng)難免存在一定不足之處,應(yīng)通過對(duì)系統(tǒng)的及時(shí)改進(jìn)與更新提高系統(tǒng)的泄漏檢測(cè)及定位精度,不斷完善系統(tǒng),并加強(qiáng)對(duì)系統(tǒng)的維護(hù),進(jìn)而確保系統(tǒng)能夠長(zhǎng)期有效的運(yùn)行。
[Abstract]:Because of the long distance and complex working conditions of oil pipeline, it is far from enough to monitor leakage by manual inspection. It is difficult for a single pipeline leakage detection method to achieve accurate pre-alarm and location of leak point.Up to now, the oil pipeline leak real-time monitoring system has been a lot of research and application, but there are shortcomings can not be perfect, so,There is still room for improvement and research value for the study of oil pipeline leakage real-time monitoring system.This paper briefly introduces the current situation of pipeline in our country and the development of leak detection technology at home and abroad, and makes a comparative analysis of several methods of leak detection and leak location in oil pipeline commonly used at present.Based on the theory of negative pressure wave, the oil pipeline leakage real-time monitoring system combined with SCADA system (data acquisition and monitoring system) is studied. The system is applied to Shen-Xing oil pipeline in practice.The SCADA system mainly adopts the method of pipeline leakage detection and leakage detection combined with the theory of negative pressure wave to detect the leakage of pipeline and locate the leakage point, and uses the method of negative pressure wave to detect the leakage of pipeline, and needs to determine its propagation speed.At the same time, considering the response time difference of the pressure transmitter located at both ends of the pipeline and overcoming the influence of noise, this paper adopts the global positioning GPS system to correct the time of the computer system at the head and end of the pipeline to realize the unification of the time.The method of signal processing is used to improve the accuracy of leak detection and leak location, and the discrete wavelet transform is used to extract the edge of transient pressure wave signal.In order to separate the characteristic points of the information accurately from the noise such as electromagnetic interference in the industrial field, the wavelet transform is calculated by the filter bank method.This leakage monitoring system is designed to provide new ideas and methods for pipeline leakage real-time monitoring, which is at a higher level in China and has a higher application value in oil pipeline real-time leak detection and location.However, there are some shortcomings in the system. It is necessary to improve the leak detection and positioning accuracy of the system through the timely improvement and updating of the system, improve the system and strengthen the maintenance of the system, so as to ensure that the system can run effectively for a long time.
