The development of a design methodology for dynamic power distribution management on a civil transport all electric aircraft

摘要

School of Engineering, Cranfield University, UK;School of Engineering, Cranfield University, UK;%This paper presents a methodology for more efficient systems power distribution management with the purpose of minimizing the rated power generating capacity and the mass of the electrical power system in an All Electric Aircraft (AEA). The power supply priority levels of all loads requiring management will be discussed and developed. The power request equations and control equations of electrical loads will be established. Furthermore, the electrical system architecture, distributed power distribution system and the dynamic power distribution management system for all-electrical aircraft are presented. By using the method of dynamic power distribution management, all the electrical consumers and sub-systems powered by electricity can be managed effectively. The performance of aircraft can be optimized due to reduced peak load requirement of the electrical system.
