description: The aim of the final qualification work is to optimize the existing power supply scheme for consumers.
In this work, it was required to familiarize themselves with the process of designing cable lines, select the necessary cable sections, consider ways of laying it and recommendations for direct construction, as well as familiarize themselves with remote control devices.
Calculation of the cable cross-section was performed by the method of economic current density. Then, the selected cable cross-section was checked for heating under normal and emergency conditions in the COMSOL Multiphysics program. The results of calculating the cross section by the method of economic current density were compared with the selection of the cable cross section according to the load schedule.
Also, in the COMSOL Multiphysics program, 2 ways of laying a cable in a troughing were compared, namely, linear and triangle. Plots of temperature distribution and magnetic field induction were obtained.
Such devices as a recloser of the PBA / TEL-10-12.5 / 630 UHL1 brand and a linear disconnector of the RMNSA type were considered as remote-control devices.
Having considered several options for optimizing the cable network presented in the work, load schedules were obtained, which show that the maximum heating of the cable is achieved during hours of maximum load, then at times of minimum load the temperature drops to minimum values.
After calculating the cost of the cable for different ways of laying the cable, we concluded that it is economically feasible to use cables of smaller sections, divided into sections, than using a single cable section for powering all consumers on the line.
