Description
Technical Field
The invention relates to the technical field of natural gas monitoring and emergency treatment, in particular to a natural gas conveying pipeline omnibearing monitoring analysis and emergency treatment system and an operation method thereof.
Background
The reform is open, the Chinese energy industry develops rapidly, but the structure is unreasonable, and the specific gravity of coal in primary energy production and consumption is up to 72%. A large amount of fire coal causes the atmospheric environment to be continuously deteriorated, and the development of clean energy and the adjustment of an energy structure are imminent. The west-east gas transportation engineering is an important component of the natural gas development strategy in China, natural gas in a Tarim basin, an Ordos basin and a middle Asia in Xinjiang is taken as a main gas source, the Yangtze delta area and the coastal area in south China are taken as target consumption markets successively, a main pipeline, an important branch line and a gas storage reservoir are taken as main bodies, and users along the line are connected to form a natural gas supply system which traverses the east-west China.
The factors for ensuring the normal transportation of the natural gas transportation pipeline include: 1. normal delivery pressure, natural gas are at long distance pipeline transportation in-process, and energy constantly consumes, and pressure constantly reduces. In order to ensure the conveying pressure, a compressor station is usually arranged at a certain distance from the starting point and in the middle of the pipeline, so that the natural gas with reduced pressure after being conveyed for a certain distance is pressurized, and the natural gas is ensured to be continuously conveyed to the next pipeline; 2. normal delivery temperature; 3. no fault leakage point; 4. an omnibearing monitoring, analyzing and managing system.
However, it is not easy to implement the omnibearing monitoring and automatic emergency treatment of the natural gas pipeline, not only the pressure, flow and leakage of the delivery pipeline are monitored in real time, but also the failure cause and failure section are analyzed quickly and accurately by the system and the automatic emergency treatment is carried out, which increases the difficulty of the system undoubtedly, and the solution of these problems is urgent.
The current innovative technology for monitoring natural gas pipelines is searched as follows:
patent document 1: the invention provides a natural gas pipeline leakage positioning method and a natural gas pipeline leakage positioning device, CN107228282A, 2017.10.03, wherein the method comprises the following steps: acquiring data signals on two sampling points of a natural gas pipeline by using a sensor to obtain a first data signal and a second data signal; decomposing the first data signal and the second data signal by using an ELMD algorithm, and obtaining an effective PF component of the first data signal and an effective PF component of the second data signal; and respectively determining a time delay value between the first data signal and the second data signal by using the effective PF component of the first data signal and the effective PF component of the second data signal, and determining the leakage position of the pipeline according to the time delay. The invention utilizes the total local mean decomposition algorithm to decompose the data collected by the sensor and obtain the effective PF component of the data signal, thereby greatly improving the positioning precision of the pipeline leakage. However, this patent document not only needs to perform on-site sampling, but also needs to perform examination by continuously reducing the range in a segmentation manner during the examination process, which undoubtedly increases the operation difficulty.
Patent document 2: the invention discloses a leakage detecting system of an underground gas pipeline and a leakage detecting method of the underground gas pipeline, CN107131429A, 2017.09.05, the invention comprises the following components: the leaked fuel gas conveying piece is used for receiving the fuel gas leaked from the fuel gas pipeline and conveying the fuel gas leaked from the fuel gas pipeline into a valve well of an underground fuel gas pipeline; the detector is arranged in the valve well and used for detecting the gas leaked by the gas pipe and the valve in the valve well; the signal transmission device is in communication connection with the detector and is used for receiving the signal from the detector and transmitting the signal outwards; and the monitoring center is used for receiving the signal from the signal transmission device and analyzing the received signal so as to monitor the operation of the gas pipeline. This secret gas pipeline leak hunting system can in time effectively discover the condition of revealing of gas underground pipe network, and accurate quick locking gas reveals the well section, the concrete position of revealing even to for the operation personnel carry out emergency treatment and reserve the time, prevented the emergence of incident. However, this patent document only monitors the valve well of the gas pipeline, and does not perform an omnidirectional monitoring function, and in addition, it cannot automatically perform emergency treatment at the first time.
