description: The subject of the study is the automatic input of the reserve of the main switchboard RU-0.4 kV. The main purpose of the master's thesis is to compile and study the automatic transfer circuit based on the controller, determine the network parameters, such as the magnitude of the current of a single-phase short circuit, three-phase short circuit, load currents, current settings of protective devices that affect the circuit of automatic transfer of the reserve. To solve the tasks in the final qualifying work, the general logical method was used. Practical significance. The results obtained can be widely used in performing such tasks, since the network under consideration, for which automatic reserve input is provided, is not unique and can be changed and supplemented indefinitely.Conclusions. As a result of the research, the shortest response time of automatic transfer units among the largest manufacturers in the Russian market was determined, a patent review of similar solutions was carried out, the values of network parameters were obtained, on which the choice of protective equipment depended, equipment specifications were drawn up, and the design of the main switchboard was presented. This work has practical application, since the presented supply network is a real infrastructure object. Further development of the topic is possible provided that the presented solutions are replaced with similar ones in terms of their characteristics and parameters.
