The embodiment of the invention discloses a series hybrid electric propulsion aircraft power supply system and a power flow control method, in the power supply system, a generator full-control rectification device is of a three-phase full-control rectification structure, alternating current generated by a generator is rectified and then output to a direct current bus, and the bus voltage is controlled; the energy storage battery is connected to the bus through the energy storage buck-boost conversion device to form an energy storage subsystem and control the output/input power of the energy storage subsystem; the full-control rectifying device and the energy storage buck-boost conversion device are respectively provided with a circuit breaker before being connected to the bus, and the connection between the corresponding devices and the bus is disconnected through the circuit breakers when a fault occurs. According to the technical scheme provided by the embodiment of the invention, the problems that the selection of the output voltage of the energy storage battery is limited, the energy storage battery is in an uncontrolled state and the power consumption is low due to the fact that the energy storage battery is directly connected to the bus to realize that the battery and the generator jointly provide electric energy for the motor in the existing tandem hybrid aircraft are solved. And the service life of the energy storage battery is shortened.

    本发明实施例公开了一种串联式混合电推进飞机供电系统及功率流动控制方法,供电系统中,发电机全控整流装置为三项全控整流结构,将发电机产生的交流电经整流后输出给直流母线,并且控制母线电压;储能电池通过储能升降压变换装置接入母线,形成储能子系统,并控制其输出/输入功率;全控整流装置和储能升降压变换装置在接入母线前,分别设置有一个断路器,故障时通过断路器断开相应装置与母线的连接。本发明实施例提供的技术方案解决了现有的串联式混合动力飞机,由于通过将储能电池直接接入母线实现电池和发电机共同为电动机提供电能,从而导致储能电池的输出电压选择受限,且储能电池处于不控状态,从而降低储能电池寿命等问题。
