description: In the final qualifying work, the electrical part of a new residential building with luxury apartments was designed. At the first stage of design, the general characteristics and composition of electrical receivers of a residential building are considered. Further, the calculation of electrical loads was performed and a power supply scheme was developed taking into account the requirements for consumers of the first and second reliability categories. Then, the necessary power of the compensating device is selected to provide the required power factor. Based on the previous results of the calculation, all power cables were selected and a check was made for permissible relative voltage deviations. At the second design stage, possible emergency modes were simulated and short-circuit currents were calculated in the most critical sections of the electrical network. Based on the results of the calculation, the choice of electrical equipment and protection devices was made. At the final stage, a schematic single-line diagram of the main switchboard and a potential equalization scheme were drawn up for the safe operation of networks.
