As an essential subsystem of spacecraft, power supply system aims to convert solar energy to electricity and distribute power to load equipment. In this paper, a modeling scheme is proposed involving solar array wing, lithium-ion battery packs, shunt regulator, charge regulator, etc. Accordingly, a Modelica-based multilevel (component-device-system) library is developed based on the typical structure and principle of power subsystem for earth's orbit. With the utilization of MWORKS platform, \(S^{3} R\) and \(S^{4} R\) systems are built and simulated on the integration of library devices, which verifies the validation of extensible and reusable digitization of spacecraft power system.

摘要

As an essential subsystem of spacecraft, power supply system aims to convert solar energy to electricity and distribute power to load equipment. In this paper, a modeling scheme is proposed involving solar array wing, lithium-ion battery packs, shunt regulator, charge regulator, etc. Accordingly, a Modelica-based multilevel (component-device-system) library is developed based on the typical structure and principle of power subsystem for earth's orbit. With the utilization of MWORKS platform, \(S^{3} R\) and \(S^{4} R\) systems are built and simulated on the integration of library devices, which verifies the validation of extensible and reusable digitization of spacecraft power system.
