Abstract

It is conducted that power characteristic variation simulation of electric propulsion system that uses fuel cells, solar cells and a battery as power sources. Combining each power source, 400W electric propulsion system have been modeled and verified. In result, without active control logic, it is confirmed that battery's power response is faster than other power sources at starting and transient condition, fuel cell and solar cell are a major electrical power during cruise condition. After completing flight, SOC is 24.2% at the winter solstice and is 93% at the summer solstice, It is revealed that active power control for sustaining proper SOC is necessary as a securing the system safety and effective power distribution.

본 논문에서는 연료전지, 태양전지, 배터리를 동력원으로 사용하는 전기추진시스템의 전력특성변화에 대한 시뮬레이션에 관하여 기술하였다. 각 전력원을 통합하여 400 W급 전기 추진시스템에 대하여 모델링 및 시뮬레이션을 수행하였다. 그 결과 능동 제어로직이 없어도 배터리는 시동 및 과도상태에서 다른 동력원에 비해 빠른 출력반응을 보였으며, 연료전지와 태양전지는 순항영역에서 주 전력 공급원의 역할을 수행함을 확인하였다. 비행 후 동지때 SOC는 24.2%이고, 하지에는 93%로 시스템 안정성 확보 및 효율적인 동력분배 차원에서 적정 SOC를 유지하기 위하여 능동 전력제어가 필요함을 알 수 있다.
