Embodiment Construction
[0098] In order to make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0099] The embodiment of the present invention provides a method for determining the degree of influence of pipeline network operation factors, such as figure 1 As shown, step 101-step 104 are included. Each step will be described in detail below.
[0100] In step 101, the pipe network reference values corresponding to multiple preset factors, the change values of multiple sub-factors included in each preset factor, and the operating values of each sub-factor under multiple working conditions are obtained respectively.
[0101] In this step, multiple preset factors may include gas source volume, gas source pressure, reduced gas consumption due to shutdown of large industrial users, reduced gas consumption due to regional gas shutdown, increased ...

The present invention provides a method and device for determining the degree of influence of pipeline network operation factors. The method includes: separately obtaining the pipeline network reference value corresponding to multiple preset factors, and the change value of multiple sub-factors included in each preset factor , and the operating value of each sub-factor under multiple working conditions; according to the pipe network reference value corresponding to each preset factor, the change value of multiple sub-factors included in each preset factor, and the multiple sub-factors of each sub-factor The operating value under each working condition is calculated to obtain the change sensitivity of each preset factor; according to the change sensitivity of the multiple preset factors, the degree of influence of the multiple preset factors is determined. The invention can quantitatively determine the influence degree of the pipe network operation factors.
Description
technical field [0001] The invention relates to the technical field of oil and gas transportation, in particular to a method and a device for determining the degree of influence of pipeline network operation factors. Background technique [0002] The operation of the pipeline network is affected by many factors, and determining the degree of influence of each factor has important guiding significance for the design and operation of the pipeline network. At present, domestic and foreign studies have been carried out on the influence of pipeline network operation factors. [0003] In related technologies, when studying the influence of pipeline network operation factors, the overall change law of pipeline network load is obtained by collecting data and analyzing it. [0004] In the process of realizing the present invention, the inventor has found that there are at least the following problems in the prior art: [0005] Related technologies can only qualitatively evaluate th...
