초록

전 세계적으로 온실가스 및 대기 오염물질 배출 저감을 위한 환경 규제가 강화되고 있고, 그에 따라 여러 가지 대책들이 마련되고 있다. 또한 환경오염 최소화와 더불어 효과적이고 합리적인 에너지 절감 방법에 대한 필요성이 점차 커지고 있는 실정이다. 선박 분야의 경우에는 친환경 선박 개발이 활발히 연구되고 있으며 배기가스 배출저감, 대체 연료 개발, 새로운 추진 방식의 선박 등이 이러한 연구 범주에 속한다. 본 논문에서는 하이브리드 전기추진선박에 대한 기본 개념을 제시하고, 선박 운전환경 분석에 따른 하이브리드 전기추진선박의 전력공급 시스템 배터리 단독 운전, 발전기 단독 운전 및 전 출력 운전 모드로 구성하고 각 운전 모드별 속도, 전류, 전압 및 출력 특성을 분석하였다.

Worldwide environmental regulations have been enhanced for emission reduction of greenhouse gases and air pollutants; accordingly, some measures were prepared. Furthermore, the need for effective and reasonable energy-saving methods is growing in accordance with that for environmental pollution minimization. In the case of marine engineering, techniques for the development of eco-friendly vessels have been actively studied, including reduction of exhaust gas emissions, development of alternative fuel, and development of a new propulsion system. In this study, we presented the basic concepts and analyzed the speed, current, voltage, and output power characteristics of each operating mode, i.e., operating mode of battery, generator, and full power.
