空间核动力平台电力管理系统的设计

空间核动力平台是一种全新的电源推进一体化航天器,其电力系统具有三相交流输出、工况多且复杂、母线电压体制多等特点。为了解决空间核动力平台负载供电诸多难题,通过对系统功能、负载类型、母线体制、组成配置、工作模式、控制机制等方面论证分析,提出了一种新型空间核动力平台电力管理系统架构。其中,变配电系统从硬件实现角度解决了基于布雷顿热电转换系统输出为负载稳态供电问题,自主控制系统从软件控制角度解决了主能源、辅助能源等多能源间流动控制以及负载暂态匹配问题,这为未来空间核动力平台电力管理系统研究工作奠定了基础。

Design of Power Management System at Space Nuclear Power Platform

Space nuclear power platform is a new integrated spacecraft with power propulsion. In the platform, the power system has the characteristics such as three-phase alternating current (AC) output, multiple and complex working conditions, and many kinds of bus voltage systems. In order to solve the power supply problems of space nuclear power platform, through the demonstration and analyses of the system function, load type, bus system, composition and configuration, working mode, control mechanism, etc., a new power management system architecture for space nuclear power platform is proposed, in which the stable power supply problem based on Brayton thermoelectric conversion system output is solved by the power transformation and distribution system from the perspective of hardware implementation and the problems of multi-energy flow control and load steady-state power supply are solved by the autonomous control system from the perspective of soft control. This lays the foundation for the future research on the power management system of space nuclear power platform.
