Research On The Key Technologies Of Modern Aircraft Remote Power Distribution

In the more electric trend of modern aircraft, the number of airborne electrical equipment will dramatically increase and the aircraft electricity consumption will rapid rise, which will increasingly highlight the importance of aircraft power distribution system. Advanced foreign aircraft- such as the B787 and A380 aircraft have been used the remote automatic distribution system, which has improved power distribution reliability and overall performance of the aircraft. Therefore, to research the two key technologies- Bus technology and solid-state power distribution technology has important practical significance for the maintenance of more electric aircraft and the research of China-made large aircraft.This thesis focuses on the two key technologies of modern aircraft remote power distribution system, researches the structure and frame format characteristics of CAN, TTP / C and Arinc664 Bus used on the aircraft remote automatic distribution system, analyzes the advantages and disadvantages of the three Bus and the structure of solid-state power controller SSPC. The realization of CAN communication is expounded from two aspects of hardware circuit and software program, the design of AC and DC SSPC is discussed from power switch module, drive control and protection module, voltage and current sampling module and I2 t inverse time overcurrent module so on several aspects.Finally, the development of the key simulation components RPDU, CBIC and RDC build a B787 aircraft remote power distribution system demonstration platform, which intuitively displays the application of bus technology and solid-state power distribution technology in modern aircraft remote power distribution systems.
