摘要：发电机控制器设计在飞机电源系统设计中起到至关重要的作用，因而对其进行建模仿真就很有必要。航空技术的迅猛发展，对电源系统的可靠性和供电品质提出了更高的要求，传统单一学科仿真软件已无法满足建模需求。Dymola软件是多学科系统仿真工具，且在航空航天等领域得到了日益广泛的应用。通过Dymola软件对发电机控制保护功能进行了建模与仿真，并验证了模型的正确性与准确性。模型遵从模块化仿真的要求，使用范围与灵活性均较高。

Abstract: 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.
