Abstract

Because of recent interests in energy conservation and prevention of environmental pollution, research related to these topics is increasing. The U.S. Navy has started to study the HED (hybrid electric drive) system in order to improve the COGAG propulsion system's fuel efficiency in AEGIS destroyers. (This ship's fuel consumption is 40% of the total fuel consumption of the U.S. Navy.) In addition, the Korean Navy is considering applications of the HED system in AEGIS destroyers. The purpose of this study is to analyze the U.S.A.'s HED system and to simulate its generating mode energy saving rate using LabVIEW. The results confirmed that the fuel savings are about 700 kg/h.

화석연료 사용이 증가함에 따라 온실가스로 인한 세계적인 지구온난화 문제가 심각한 편이다. 이에 따라 에너지 절감과 환경오염에 대한 관심이 높아지고, 이에 대한 연구가 활발히 전개되고 있다. 최근, 미 해군에서는 해군 에너지 소비량의 40%를 차지하고 있는 이지스 구축함의 COGAG 추진체계의 연료 효율을 개선하기 위해 HED(Hybrid Electric Drive) System에 대한 연구를 시작했다. 한국에서도 DDG-51급인 이지스 함을 보유하고 있으므로 HED system에 대한 연구를 통해 연료 효율을 개선시킬 수 있다. 따라서 본 연구에서는 미 해군의 HED system을 분석하고 LabVIEW를 통해 HED를 발전기 모드로 사용하였을 경우 에너지 절감량에 대해 시뮬레이션을 진행하였다. 시뮬레이션 결과 평균적으로 700kg/h의 연료가 절감됨을 확인하였다.
