The embodiment of the invention discloses a high-voltage direct-current propulsion system suitable for a distributed electric propulsion aircraft, in each channel of the system, a storage battery pack is connected with a bus bar through a main channel contactor, the storage battery pack supplies power to the bus bar, and the main channel contactor controls the on-off state of the storage battery pack and the bus bar; the four bus bars are sequentially connected through the four switching channel contactors to form a power supply loop, and the switching channel contactors are used for controlling the on-off states of the bus bars; the system control unit is connected with the storage battery pack, the bus bar, the main channel contactor and the switching channel contactor and used for monitoring the system state, executing system power supply switching control and driving motor control. According to the technical scheme provided by the embodiment of the invention, the problem that engineering application of a high-voltage direct-current propulsion system of a distributed electric propulsion aircraft is difficult to realize due to the fact that an existing electric propulsion aircraft mainly aims at small-power centralized electric propulsion for navigation is solved.

    本发明实施例公开了一种适用于分布式电推进飞机的高压直流电推进系统,系统的每个通道中,蓄电池组通过主通道接触器与汇流条连接,蓄电池组向汇流条供电,主通道接触器控制蓄电池组与汇流条的通断状态;4个汇流条通过4个转换通道接触器依次连接,形成供电环路,通过转换通道接触器控制汇流条之间的通断状态;系统控制单元分别与蓄电池组、汇流条、主通道接触器、转换通道接触器相连接,用于监控系统状态以及执行系统供电转换控制、驱动电机控制。本发明实施例提供的技术方案解决了现有电推进飞机主要针对通航用小功率集中式电推进,难以实现对分布式电推进飞机的高压直流电推进系统的工程应用的问题。
