The invention provides an aircraft multi-redundancy power supply system architecture based on an energy storage device. The aircraft multi-redundancy power supply system architecture is composed of a low-voltage direct-current bus bar, a high-voltage direct-current bus bar, an electric energy storage device, an electric energy feedback controller, a motor controller and a motor. When the airplane normally supplies power and loads work, the low-voltage direct-current bus bar and the high-voltage direct-current bus bar supply power to the motor controller and the motor to achieve motor control and driving functions, and when the motor is subjected to regenerative braking, feedback electric energy is stored in the energy storage device through the electric energy feedback controller to be stored, so that the motor energy recovery function is achieved. And when the low-voltage direct-current bus bar breaks down, the high-voltage direct-current bus bar breaks down or the low-voltage direct-current bus bar breaks down and the high-voltage direct-current bus bar break down simultaneously, the reliability of the direct-current power supply system is improved through a multi-redundancy power supply control strategy.
本发明提出一种基于储能装置的飞机多余度供电系统架构,由低压直流汇流条、高压直流汇流条、电能存储装置、电能回馈控制器、电机控制器及电机构成;在飞机正常供电及负载工作时,由低压直流汇流条与高压直流汇流条向电机控制器及电机供电,实现电机控制及驱动功能,在电机回馈制动时通过电能回馈控制器将回馈电能存入储能装置进行电能存储,实现电机能量回收功能;并且当低压直流汇流条故障、高压直流汇流条故障或者低压直流汇流条故障与高压直流汇流条同时故障时,通过多余度供电控制策略,提高直流供电系统的可靠性。
