摘要
研究飞机电源系统供电优化问题,飞机交流发电系统多采用三级式无刷交流同步发电机,由永磁发电机、交流励磁机和主发电机组成。为了仿真飞机三级发电机,在介绍三级同步发电机结构的基础上,通过派克变换在dq0坐标系下,建立三级发电机的动态数学模型,在Saber软件平台下使用MAST语言编写同步发电机模型,结合调压器及电气负载得到三级发电机的部分动态仿真结果,仿真结果能够很好地显示三级发电机对不同负载的响应,证明了模型的正确性,为飞机电源系统的设计提供了一个有效的工具。
Three - stage synchronous generator with brushless exciter is a common structure in aircraft AC power system, which contains vice exciter, excitation machine and the main generator. In order to simulate the aircraft pow- er system, the structure of three - stage generator was introduced and its mathematical model in dq0 coordinate sys- tem was built by using MAST Language based on Saber platform. The dynamic results of the synchronous generator working with GCU and electrical loads were obtained after simulating. The results show the different responses of three - stage generator with respect to different loads, which proves the validity of the model. This model provides a more effective tool to design the aircraft power system.
