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

Based on the integrated design and airworthiness verification of civil aircraft systems, this paper completes the simulation modeling and fault modeling of the 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 a three-stage power generation system, the auxiliary power supply system uses the permanent magnet synchronous power generation system, and a battery is also included. The transmission and distribution system is responsible for the electrical power conversion and logic control in the system fault pattern. The simulation results demonstrate that the system is reasonable and effective, providing a reference for the optimal design and control of the actual aircraft electrical system.
