With the development of science and technology, a variety of secondary energy resources in traditional aircraft are gradually replaced by electrical energy and the more electric aircraft becomes the future development direction of the aircraft. The increased electromechanical loads in the more electric aircraft have higher requirements on the capacity, stability, dynamic performance and other aspects of the aircraft electrical system. Therefore, it is of great significance to study the load characteristics of the electromechanical system. Simulation technology plays a key role in the actual engineering research and development process. The aircraft electromechanical system involves multiple fields such as electrical, hydraulic and mechanical. Dymola multi-domain modeling and simulation software can meet its complex and diverse modeling needs, which is a good platform for the study of the effect of more electric load characteristics of the electromechanical system on the aircraft grid. Based on the Dymola simulation software, this paper models and simulates several typical loads of the more electric aircraft, which lays a foundation for studying the characteristics of power loads and their impact on the power supply system.
