description: The purpose of this graduate qualification work is to develop a mathematical model of transformer substation and analyze the results of mathematical modeling. The subject of this qualification study is a closed transformer substation with a change in ventilation. This study provides classification of transformers and their main parameters. The basic design of power transformer is presented, types of cooling systems for transformers are presented with a short description of each of them. Also in this work there is brief information about transformer substations and the types of their ventilation. Some methods of thermal calculation of transformers are considered: mathematical methods, electric thermal analogy method, empirical methods, modeling in CAE program. The last method was chosen for this work. The geometry of the oil transformer was created in the SOLIDWORKS program, and the geometry of a closed transformer substation with ventilation windows was created in COMSOL MULTIPHYSICS program.
