description: The topic of the final qualifying work: "Research of modes and dynamic stability of the district electric power system 110/35 kV". This work is devoted to a comprehensive study of an electric power system, which is a combination of electrical equipment and networks of different voltage classes (35 and 110 kV) operating in a general mode. As a result, the tasks were solved: 1.Selection of the main equipment of power plants and substations, selection of power transmission lines 2. Calculation (by analytical methods, by computer modeling) and construction of the steady-state operation of the electric power system, its analysis and organization of optimization measures 3. Modeling of serious (emergency) disturbances in the system (by the method of theoretical calculation, by means of special software) 4. Evaluation based on the results of the study of the dynamic stability of the designed power system, the proposal of measures to improve it The electrical equipment selected from the catalogues made it possible to build a statically stable system. The steady-state mode was built using voltage regulation resources and power compensation devices. The system proved to be stable at the design point to a single-phase short circuit. For a more severe three-phase short circuit, the possibility of implementing sequential electrical braking of generators in order to increase the stability of the system was considered.
