Abstract In this paper, the interface that should be considered for the smart load balancing system to be practical. For this, an electric rail power supply system and a smart load balancing system were modeled, and the interface characteristics were analyzed by combining them and simulating them. For the load, a resistances of 11.60MVA similar to that of a general railroad vehicle and a load of 7.56MVA that can occur while a railroad vehicle is running were used. As a result, it was confirmed that the voltage difference on the M/T may vary depending on the connection position of the load and the measurement position(SSP, SP). And it was confirmed that the voltage difference occurred differently according to the load size(11.60, 7.56MVA) too. And for the practical use of the smart balancing system, it was confirmed that optimal design of hardware, controller, etc. is necessary in consideration of all situations analyzed in this paper.
