Abstract
The paper shows the application of the method of determining critical elements in the networks of technical infrastructures in the search and analysis of the importance of critical gas industry facilities. The purpose of this method is to search for critical elements and sets of elements in network infrastructures and their ranking by importance. The paper presents an adaptation of the method for determining critical elements in networks of technical infrastructures for the model of gas supply system functioning, which consists in describing the response of the gas supply system to the failure of a single element or a group of them. Conclusions are made about the expediency of using this method in research into the search for critical gas industry objects and determining their significance.
Highlights
One of the main aspects of ensuring energy security is to create the conditions for the greatest possible degree of satisfaction of consumers with energy resources in emergency situations
The matter is that today more than 90% of Russian natural gas is extracted in one gas producing region (NadymPur-Tazovsky district of the Tyumen region)
The list of crossings of main gas pipelines in the Unified Gas Supply System of Russia has been determined, the violation of which will lead to a relative deficit of gas supplies for the system as a whole of 5% or more
Summary
One of the main aspects of ensuring energy security is to create the conditions for the greatest possible degree of satisfaction of consumers with energy resources in emergency situations. Conducted studies have shown that along with main gas pipelines crossings, a significant shortage of gas supplies through the system (5% or more) may result in a disruption of the functioning of both a separate section of the main gas pipelines located between the node compressor stations and the disruption of several such sites The determination of such sections of main gas pipelines and their combinations is complicated by the fact that in the current configuration of the Unified Gas Supply System of Russia there are about 500 edges. At this stage of the study of critical objects of the gas industry, the authors proposed the use of the method of determining critical elements in the networks. Its application is justified by the need to assess the importance of the gas sector's critical objects
