The present invention is to provide a power supply system for a ship in which an existing transformer can perform the function of an autotransformer without separately installing an autotransformer, thereby reducing the current applied when a motor is operated. The present invention relates to a power supply system for a ship comprising: a first generator and a second generator for generating electric power; a first switchboard connected to the first generator and distributing the power produced by the first generator through a main bus and trunk lines; a second switchboard connected to the second generator and distributing the power produced by the second generator through the main bus and trunk lines; a first transformer connected to the first switchgear to convert the voltage level of the generated power; a third switchboard connected to the first transformer to distribute power to loads in the ship; a second transformer connected to the first switchboard and the second switchboard, and converting the voltage level of the electric power distributed in the first switchboard or converting the voltage level of the electric power distributed in the second switchboard; and a motor connected to the first switchboard and the second transformer and driven by the electric power converted by the second transformer. 선박의 전력공급 시스템에 관한 것으로, 전력을 생산하는 제1 발전기 및 제2 발전기, 제1 발전기와 연결되고, 제1 발전기에서 생산된 전력을 주모선 및 간선을 통해 배전하는 제1 배전반, 제2 발전기와 연결되고, 제2 발전기에서 생산된 전력을 주모선 및 간선을 통해 배전하는 제2 배전반, 제1 배전반과 연결되어 생산된 전력의 전압 크기를 변환하는 제1 변압기, 제1 변압기와 연결되어 선박 내의 부하에 전력을 분배하는 제3 배전반, 제1 배전반 및 제2 배전반과 연결되고, 제1 배전반에서 배전된 전력의 전압 크기를 변환하거나, 제2 배전반에서 배전된 전력의 전압 크기를 변환하는 제2 변압기 및 제1 배전반 및 제2 변압기와 연결되어 제2 변압기에서 변환된 전력으로 구동되는 모터를 포함한다.
