Abstract

A Small-Sat Power System Design and Development should be depend on space environment such as solar wind with Electromagnetic field by hurdle of techniques. It is surmount solution of trend that will unitize and converge with power module in these days. The level of modularize means that applying Universal Middleware for payload power module requirements. The scope of target system is a main power provider module and operational subunit that can be implemented with the final power module distribution loads to consume for continuous process. A Universal Middleware strengthen to build power module from satellite power system should be accuracy and consuming data. A Power Service Module and dynamic system drive interactive management between power distribution and consumer module by Range Control. Consequently, suggesting evaluation, unexpecting payload system power consumer that makes fine variable resources in the development design process and efficiency.

소형인공위성 전력시스템체계 설계 및 개발방법은 태양풍 자계인 우주환경의 영향에 따라 기술적 제약이 큰 편이다. 이를 극복하기 위해 최근 전력모듈을 융합화와 유닛화 단계별 개발 방식으로 변화 하고 있다. 모듈화 단계에서는 탑재체 전력공급 모듈 요구조건과 함께 유니버설미들웨어를 사용하여 융합하였다. 융합모듈화대상은 탑재체에서 전력분배, 부하관리, 서브유닛의 전원공급체계와 지속성을 고려한 최종모듈 설계 및 개발 단계를 범위로 한다. 본 연구는 위성본체에서 공급되는 전력모듈을 유니버설미들웨어 기반으로 전력모듈의 정밀성과 수요처모듈데이터를 컨텐츠화 하였다. 이 동적시스템과 전력서비스 모듈화는 전력분배모듈과 전원공급모듈간 상호작용으로 Range Control 알고리즘으로 제어된다. 그리하여 전력모듈 설계단계에서 탑재체 전력수요 변수의 변동성에 따른 불확실성을 해소하고 설계의 효율성을 제시하였다.
