Abstract
The article is devoted to the search and determination of the most important combinations of gas industry objects from the standpoint of system operability. The study was carried out on the example of the Unified Gas Supply System of Russia. The study is a development of the topic of the search and determination of critical objects of the system. Cases of simultaneous failure of two disconnected and independent from each other system objects are possible. The article presents a list of the most important combinations of gas industry objects that are not included in the list of critical objects, failure of which can lead to a significant gas shortage among consumers. Their significance and impact on the performance of the Russian gas industry are shown. Conclusions have been drawn on the feasibility of searching for such paired combinations of gas industry objects from the standpoint of system operability.
Highlights
The increase in the number of major accidents in energy systems in recent years has been due to the significant depreciation of fixed assets, and the lack of significant financial investments in their reconstruction
This study examined the search for the most important combinations of gas industry objects
The definition of such combinations of gas industry objects, failure of which can lead to a gas deficit in the system as a whole, is comparable to the deficit arising from the failure of individual critical object
Summary
The increase in the number of major accidents in energy systems in recent years has been due to the significant depreciation of fixed assets, and the lack of significant financial investments in their reconstruction. Large-scale accidents in energy systems resulting from the failure of the most important system objects entail significant, sometimes irreparable, damage to consumers in the form of large short deliveries of final types of energy. Geographically dispersed energy systems are becoming more intelligent and complex every year, more closely integrated with other infrastructure systems. The failure of the most important system objects will have a negative impact on other interconnected infrastructure systems. Today it is relevant to identify the most important objects and their combinations in energy systems with the subsequent development of measures aimed at reducing the importance of such objects
