Method and device for determining facility addition scheme of natural gas pipeline network

Abstract

The invention provides a method and device for determining a facility adding scheme of a natural gas pipeline network, computer equipment and a storage medium, and belongs to the technical field of oil and gas transmission. The method comprises the steps that an existing pipe network model of the natural gas pipe network is established, whether the natural gas pipe network has the transportation increasing capacity or not is determined, on this basis, the transportation increasing pipe network model is established in combination with the transportation amount of newly-added users, bottleneck point users in the transportation increasing natural gas pipe network are found out through calculation, and multiple alternative schemes are generated according to the bottleneck point users; and inputting the plurality of alternative schemes into the pipe network model after the transmission is increased for simulation, so as to obtain a scheme meeting the gas consumption requirements of all users in the pipe network after the transmission is increased, and finally determining the scheme with the minimum implementation parameter as a target facility addition scheme. According to the technical scheme, the problem that the gas use requirement of a bottleneck point user in a natural gas pipeline network after increased transportation cannot be met is solved, and it is guaranteed that the target facility adding scheme meets the target implementation condition.

Description

technical field [0001] The present application relates to the technical field of oil and gas transmission, and in particular to a method, device, equipment and storage medium for determining a facility extension scheme of a natural gas pipeline network. Background technique [0002] With the vigorous development of my country's natural gas industry and the continuous acceleration of the construction of natural gas pipeline networks, the number of natural gas users has increased rapidly. The increase will lead to low gas pressure or insufficient gas consumption of some users, and the gas demand of users cannot be met. [0003] In related technologies, in order to solve the above problems, the capacity of the gas storage is usually expanded, or the gas consumption of the user is adjusted during peak gas consumption by optimizing the peak-shaving mode of the gas storage. [0004] However, in the above process, the plan to expand the capacity of the gas storage will be constrain...
