Modeling and Simulation of Electrical System in More Electric Civil Aircraft Considering Faults

摘要

Based on the integrated design and airworthiness verification of civil aircraft system,this paper completes the simulation modeling and fault modeling of aircraft electrical system.The aircraft electrical system is constructed in the form of dual generators and dual-channel power supply.The main power supply adopts the three-stage power generation system,the auxiliary power supply system uses the permanent magnet synchronous power generation system and a battery.The transmission and distribution system is responsible for the electrical power conversion and the logic control in the system fault-pattern.The simulation results show that the system is reasonable and effective,which provides a reference for the optimal design and control of the actual aircraft electrical system.
