| Abstract |
The regulations to reduce air pollutants from shipping industry have been strengthened by international organization such as IMO(International maritime organization). In response to these regulations, various efforts are being made to realize eco-friendly fuel and electric propulsion system. In this study, electric propulsion system based on liquid hydrogen fuel cell and battery was focused on and P-HILS was applied to analyze performance of propulsion system. P-HILS in this study used power devices supplying scaled-down power instead of power amplifier and simulation was conducted based on time series data of real tug boat. From the simulation result, the performance of propulsion system based on liquid hydrogen fuel cell and conformity between simulation model and power device are confirmed. |
