초록
Domestic and international regulations have been strengthened to reduce emissions from ships to prevent air pollution at sea. In particular, the greenhouse gases in the air pollutants generated on the coast of the country are primarily emitted from littoral small-sized fishing ships. To reduce the gas emission from littoral ships, an electric propulsion ship using a Direct Current (DC) distribution system can be introduced. In this study, to select a suitable propulsion motor for a small-sized electric propulsion ship using a DC distribution system, an induction motor and a Brushless Direct Current Motor(BLDC) were selected as propulsion motors and simulated using a power analysis program. Consequently, the speed response characteristics according to the type of propulsion motor, heat loss of the inverter, and harmonics of the power output were measured and analyzed to provide a suitable propulsion motor for a DC power distribution propulsion ship.
