Modeling and simulation of aircraft generator protection system based on Modelica language

摘要

Basic. Generator control unit design plays a crucial role in the design of the aircraft power system, therefore it's necessary to model and simulate. The rapid development of aeronautical technology puts forward higher requirements to reliability and quality of power supply system, and traditional simulation software is unable to meet the demand. Since Dymola software designed by Sweden Dynasim AB Company is a multi-disciplinary simulation software, which having been increasingly widely used in various fields. A control and protection model of the generator was proposed by using Dymola, and the correctness and accuracy of the model were verified. The model complies with the requirements of Modular simulation model, highly raising its scope of applications and flexibility.
