description: This work is devoted to the design of a step-down substation. Tasks that were solved during the project: gave a description of the design object; processed load schedules; selected the number and capacity of power transformers of the substation; selection of the main wiring diagram; calculated short-circuit currents; selected high-voltage equipment; chose relay protection and automation; calculated lightning protection and grounding. The work was carried out on the basis of the regional step-down substation, where a significant part of the factual material was collected: the graphs of the substation load in winter and summer, work with the documentation for the selection of the main and auxiliary equipment of the substation. Processing of load curves was carried out. As a result, the operation of the substation in winter and summer time was analyzed, which showed that the greatest load falls on winter time in December-January.
