Abstract:

The design and validation of satellite power subsystem is a key part of satellite design. The power subsystem has high safety and high reliability requirements, and its design is coupled with multiple factors such as satellite orbit, lighting, and work mode. Meanwhile, it needs to be associated with multi-disciplinary design such as mechanism, thermology, power supply and control. In order to realize the design and simulation of complex system quickly, conveniently and comprehensively, the model-based system engineering (MBSE) method is proposed to realize the explicit integrated expression of multi-coupling, multi-product and high-safety system of power subsystem through the model. In addition, the design, verification and optimization of multiple function points and performance points are carried out around the requirements. The results show that the power design model constructed by this method integrates design and verification, it can make a refined analysis of the system requirements, and then carry out functional and structural design, realize and optimize design of system performance indicators, and complete the closed-loop and verification of requirements, which has efficient and clear application value in engineering.

Key words: model-based system engineering (MBSE), satellite, power system, requirement analysis, architecture design
