中文摘要:

      飞机配电系统是现代飞机系统的一个重要组成部分，对于保证机载设备可靠工作、保障飞行安全起着关键作用。对民用飞机传统配电方式和现代先进配电方式进行了比较，着重对基于数据总线技术和固态功率控制技术的B787飞机的自动配电系统的构架、关键组件进行了分析研究。该分布式自动配电系统能够实现对飞机配电系统构型和电气负载的自动管理，具有高可靠性和灵活的扩展性等优势，对国产大飞机项目配电系统的设计有着极好的参考价值。

英文摘要:

      Electrical power distribution system is an important component of modern aircraft system,which plays a key role for ensuring the reliable operation and safety flying of the civil aircraft airborne equipments.The traditional aircraft power distribution system is compared with the modern advanced aircraft,and made thoroughly research in power distribution system structure and kernel unit of B787 based on the design of data network technology and solid state power control technology,and it is showed that the automatic distribution system has great advantage in system reconfiguration,load management,high reliability and flexible expansibility.Design of distribution power system made large aircraft project has an excellent reference value.
