Analysis and Optimization of Gas Field Substation Relay Protection

The gas industry plays an important role in the country's economy. The main equipment used for gas production was installed in the 1960s and 70s, and over time has reached the final stage of its operation [9], [11], [12]. Aging equipment increases the risk of accidents, which is especially critical for enterprises operating in continuous production mode. The reliability and safety of such enterprises directly depend on the condition of their equipment. In these conditions, the issue of updating and modernizing technical means becomes urgent in order to prevent possible negative consequences for the entire industry. This article analyzes the existing relay protection system of a gas field substation in order to identify its shortcomings and possible vulnerabilities. This will allow us to determine specific measures and recommendations for optimizing its operation, as well as increasing its reliability and efficiency [7], [13], [14].
