Modeling and simulation of aircraft automatic power distribution system

Abstract

The electric power distribution system is an important part in modern aircraft electric power supply system. In this paper, the fundament of the aircraft electric power distribution system is briefly described through an example. According to the aircraft electric power characteristics defined in National Military Standard, the models of important components in the distribution system are established, such as GCU, GB, BTB, TRU. The logic relations of these components are abstracted. The approaches to establish distribution system models are discussed. The distribution system of the new type of aircraft is simulated applying the models. The validity of the models is verified by comparing the simulation waves and the experiment wave.
