Embodiment 1

[0031] The design process of the aircraft modular power grid experimental device of this embodiment is as follows:

[0032] Research the power supply scheme suitable for large general-purpose passenger aircraft, and establish the topology of the power supply network used.

[0033] Such as figure 1 As shown, the single-channel module is mainly composed of a generator system, a fuel cell system, a high-voltage DC battery system, a supercapacitor system, and a DC bus bar. The generator system, fuel cell system, high-voltage DC battery system, and supercapacitor system are respectively connected to the DC bus bar through contactors. The DC bus bar has ports to connect other single-channel modules as well as loads.

[0034] Multiple single-channel modules are connected through the ports provided by the DC bus bar to form a grid structure of the power generation system, in which generators and fuel cells constitute a distributed power generation system that supplies power to the 2...

Abstract

The invention discloses a single-channel module of an airplane distributed power grid structure, a power generation system and a control method. The single-channel module comprises a generator system,a fuel cell system, a high-voltage direct-current storage battery system, a super capacitor system and a direct-current bus bar. The generator system, the fuel cell system, the high-voltage direct-current storage battery system and the super-capacitor system are separately connected to the direct-current bus bar, and the direct-current bus bar is provided with ports connected with other single-channel modules and a load. The power grid structure of an airplane distributed power generation system comprises a plurality of single-channel modules, and the single-channel modules are connected through the ports provided by bus bars of the single-channel modules. According to the aircraft distributed power generation system structure and the control method thereof provided by the invention, thestability and flexibility of the system can be improved.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering, and in particular relates to an aircraft power grid structure. Background technique [0002] As the requirements for reliability, maintainability, and fuel economy are getting higher and higher, multi-electricity and all-electricity have become the development trend of civil aircraft and military aircraft, and are an important way to support the development of green aviation and improve tactical performance. More Electric Aircraft (AEA) and All Electric Aircraft (AEA) gradually unify secondary energy such as air pressure energy, hydraulic energy, and mechanical energy on board into electric energy, thereby simplifying the system structure and improving system reliability and maintenance performance, while improving the overall efficiency of the system and reducing fuel consumption. [0003] High Voltage Direct Current (HVDC) power supply system has significant advantages in terms ...
