Abstract

A comprehensive large-scale power system modeling technique using the multiport coupling method is developed to facilitate design and analysis of present and future spacecraft power systems. The Boeing Computer Service´s EASY5 program was used as the host software to meet various modeling and analysis needs for DC, small-signal, and large-signal analyses. Power subsystem or component model development from empirical data and reduced-order model generation using the complex curve-fitting technique are also introduced. A sample spacecraft power system, the simplified Direct Energy Transfer system, is modeled and its performance demonstrated
