随着航天器功能的增多和容量的增大,对电源系统的配置、管理、故障检测与诊断以及可靠性和可维修性都提出了更高的要求,促使航天器配电技术向着大功率和智能化方向发展。文章介绍了“天宫一号”目标飞行器电源系统采用的大功率智能配电单元,并在此基础上提出了智能能源管理单元设计。通过采用智能数据处理、固态功率控制等改进技术,将大功率智能配电系统进一步提升和完善,拓展其应用领域,以满足未来载人航天和深空探测任务发展的需要。
With the increase of spacecraft capabilities and the increase of capacity, higher requirements are placed on the configuration, management, fault detection and diagnosis, reliability and maintainability of the power supply system, prompting spacecraft power distribution technology toward high-power and high- Intelligent direction. This paper introduces the high power intelligent power distribution unit used in the power system of Tiangong One and the target aircraft, and on this basis, presents the design of intelligent energy management unit. Through the use of intelligent data processing, solid state power control and other improved technologies, the high-power intelligent power distribution system will be further enhanced and improved to expand its application fields to meet the needs of future manned space and deep space exploration missions.
