航天器电源建模仿真综述与展望

The power supply system is an essential subsystem of spacecraft, which is used to generate, store and distribute electric energy. With the explosive growth of the number of spacecraft, the modeling and simulation of power supply has become a research hotspot in the field of spacecraft health management, intelligent operation and maintenance. In view of this, this article firstly summarizes the classification, composition and development trend of spacecraft power supply. Then, from the perspective of spacecraft health management and intelligent operation and maintenance, spacecraft power supply modeling and simulation technology framework, mechanism modeling, data-driven modeling, digital twin fusion modeling method of typical components, spacecraft power supply simulation technology and software, typical application of modeling and simulation are reviewed. Finally, the technical challenges and development trends of spacecraft power supply modeling and simulation are summarized and analyzed. This article is expected to provide some references for researchers in the fields of spacecraft power supply health management, spacecraft power supply modeling and simulation, and digital twins.
