Evaluation of cable and busbar system in multiconductor distribution systems in terms of current and magnetic field distributions

Abstract

The selection of power distribution components is of great importance in electrical facilities. Cable and busbar systems are widely used applications, such as electric vehicle charge stations, microgrids and energy storage systems, for power distribution in the distribution grid. In this study, the current distribution on the parallel conductors and magnetic field distributions around cable and busbar structures is evaluated for studied application where the power is distributed using a cable system between a converter transformer and a converter. All modeling and analyzes are conducted using ANSYS Electronics Suite software, by applying balanced and pure sinusoidal current excitation. Obtained results show that, when the busbar system is installed for power distribution, current distribution between parallel conductors is decreased to the negligible level, and the calculated magnetic field density is about 73.7% lower than the cable system.
