随着大功率通信卫星、高分辨率SAR卫星、大功率电推进航天器、核动力航天器、大型在轨服务站等对超大功率能源系统需求不断增强,100 kW超大功率电源系统成为未来大功率航天器电源系统的发展趋势。文章结合航天器电源系统研究基础,对100 kW电源系统的高压、大功率、分布式的任务特点进行分析,设计一种分布式可重构电源系统,提出了系统拓扑架构和相应的控制策略,并对高压大功率变换控制技术、多通道能源管理技术、高压大功率元器件技术和系统可靠性、安全性技术进行研究。对文章提出的电源系统进行软件建模和仿真,结果表明:100 kW电源系统拓扑架构和管理控制策略合理可行,系统稳定性较好,鲁棒性强,可为后续大功率航天器电源系统研究和设计提供参考。
With the increasing requirements of ultra-high power system for high-power communications satellites,high-resolution SAR satellites,high-power electric-propulsion spacecraft,nuclear-power spacecraft and on-orbit large service stations,100kW ultra-high electrical power system has become a developing trend of future high-power spacecraft electrical power system.Based on the deve￣lopment foundation of spacecraft electrical power system,the high-voltage,high-power and distributed task features of 100kW electrical power system are analyzed.A distributed reconfigurable electrical power system is designed.A topology of distributed electrical power system and its control strategy are proposed.The key technologies including high-voltage and high-power conversion control technology,multi-channel power system management technology,high-voltage high-power device technology and system reliability and safety technology are studied.And then,the proposed power system is modeled by software and simulated.The results show that the topology and management control strategy of 100kW electrical power system is reasonable,with relatively high stability and robustness.This design provides a reference for future high-power spacecraft electrical power system research and design.
