description: Within the framework of this work, a model of a gas supply enterprise was studied, characterized by the predominance of motor load, particularly asynchronous motors. The work examines the ability to maintain dynamic stability of asynchronous and synchronous motors and their self-starting capabilities under various operating modes. During the work, the following tasks were solved: 1. The relevance of the problem of short-term power supply disruptions was substantiated, highlighting its significance for the reliability of gas supply enterprise operation; 2. Accurate and exhaustive definitions of the concepts of electrical power system stability and asynchronous load stability are provided, along with a thorough analysis of the conditions for restoring normal operation of the consumer after power outages. 3. A detailed description of the investigated gas supply system complex has been conducted, and a calculation of the established regime has been performed using the "RastrWin3" software. 4. A dynamic stability calculation of the investigated system has been performed using the "Mustang" software, including the assignment of asynchronous motor parameters, modeling of residual voltage on the motor terminals, and modeling of various calculated disturbances; 5. Measures to improve dynamic stability were developed and proposed, aimed at ensuring the reliable operation of the gas supply enterprise. Within the framework of developing measures to enhance the dynamic stability of the gas supply complex power supply system, the implementation of an automatic reserve switching system was proposed, which will ensure more reliable system operation during short-term power supply disruptions. Additionally, an investigation was conducted on the dependence of asynchronous motor self-starting time on the asynchronous machine load factor.
