Abstract

The article is devoted to the problem of finding critical combinations of gas industry objects from the standpoint of ensuring energy security. A critically important object is the partial or complete failure of which can cause significant damage to the country from the fuel and energy complex as a whole or within a separate energy system. Gas transportation networks in Russia and Europe are very extensive, branched, and have many intersections and backup gas pipelines. Therefore, cases of simultaneous failure of several system objects are possible. The article presents the results of calculations in which the authors identify the most significant combinations of gas transportation network objects from the point of view of providing consumers with gas. The significance and influence of these combinations on the performance of the Russian gas industry is shown. Conclusions are drawn about the feasibility of searching for critical combinations of gas industry objects.
