Description
Technical field
The present invention relates to natural gas monitoring, urgent technique field, specially a kind of natural gas transmission pipeline is comprehensive
Monitoring analysis, emergent treatment system and its operation method.
Background technology
Since reform and opening-up, Chinese energy industrial development is rapid, but structure is very unreasonable, coal primary energy production and
Proportion in consumption is up to 72%.A large amount of fire coals make atmospheric environment constantly deteriorate, and development clean energy resource is readjusted the energy structure
It is extremely urgent.West-East National Gas Transmission Project is the important component of Development of Natural Gas In China, it is with Tarim Basin In Xinjiang, Hubei Province
Er Duosi basins and Central Asia natural gas are gas source, are successively disappeared using China Yangtze River Delta Region and Coastal Areas of South China as target
Take market, based on main pipeline, important branch line and gas storage, user along connection forms and traverses the natural of Western China east
Gas air supply system.
Ensure natural-gas transfer pipeline normally conveyed because being known as：1. normal discharge pressure, natural gas it is long away from
From in pipe conveying procedure, energy constantly consumes, and pressure constantly reduces.In order to ensure discharge pressure, usually in the starting point of pipeline
Compressor station is set on the certain distance of midway, to the natural gas boosting of the pressure reduction after certain distance conveys, ensures it
Continue on to next pipeline；2. normal delivery temperature；3. fault-free leakage point；4th, comprehensive monitoring analysis and management system.
However, to realize that the comprehensive monitoring of natural gas line, automatic emergency processing are not easy, not only to monitor in real time
The pressure of feed-line, flow and whether have situations such as leakage, but also want the quick Accurate Analysis of system be out of order reason and therefore
Barrier section simultaneously carries out automatic emergency processing, undoubtedly increases the difficulty of system, and the solution of these problems is extremely urgent.
Now for the innovative technology in terms of natural gas line monitoring, retrieve as follows：
Patent document 1：《A kind of gas pipeline leakage localization method and device》, CN107228282A, 2017.10.03,
The present invention provides a kind of gas pipeline leakage localization method and device, wherein the method includes：Using sensor in day
Gathered data signal on two sampled points of right feed channel, obtains the first data-signal and the second data-signal；It is calculated using ELMD
Method decomposes first data-signal and the second data-signal, and obtains effective PF components and second of first data-signal
Effective PF components of data-signal；The effective PF components for being utilized respectively the first data-signal and the second data-signal determine the first number
It is believed that the time delay value number between the second data-signal, and determine pipe leakage position according to the time delay.The present invention is using totally
Local mean value decomposition algorithm carries out resolution process, and obtain effective PF components of data-signal to the data that sensor acquires, from
And greatly improve the positioning accuracy of pipe leakage.But the patent document not only needs to be sampled on the spot, but also is checking
It needs constantly to be segmented in the process and reduces the scope to be investigated, undoubtedly increase operation difficulty.
Patent document 2：《Underground gas pipeline leak detection system and underground gas pipeline leak hunting method》, CN107131429A,
2017.09.05, the present invention includes：Fuel gas transmission part is revealed, for receiving the combustion gas of fuel gas pipeline leakage, and by gas pipeline
In the fuel gas transmission of leakage to the valve well of underground gas pipeline；Detector, in valve well, for detecting Gas Pipe leakage
Combustion gas and the valve leaks in valve well combustion gas；Signal transmitting apparatus is communicated to connect with detector, is come from for receiving
The signal of detector, and by the signal unofficial biography；Monitoring center for receiving the signal from signal transmitting apparatus, and will receive
To signal analyzed, so as to being monitored to the operation of gas pipeline.The underground gas pipeline leak detection system can be timely
It effectively finds the leak case of Underground pipe network, quickly and accurately locks the specific location of gas leakage well section or even leakage,
So as to which the time has been reserved in the carry out emergency processing for operating personnel, it is therefore prevented that the generation of safety accident.But the patent document is only
It is monitored for the valve well of gas pipeline, is not played the role of comprehensive monitoring, it in addition to this, can not be
One time carried out emergency processing automatically.
In conclusion although above-mentioned technological innovation solves asking for natural-gas transfer pipeline leak detection to a certain extent
Topic, but cannot still solve the pressure of comprehensive monitoring feed-line, flow and whether have situations such as leakage and accurate point quick
Failure cause and the question of substance of faulty section is precipitated.
