摘  要:变频交流(AC)发电机在三级式恒频交流同步发电机的基础上发展而来,其宽的变速工作范围给发电机系统带来了新的特点,而变频交流起动发电机又是在变频交流发电机基础上进一步发展的,其运行条件及工作特性更为复杂。首先介绍变频交流发电机的结构特点,并给出其设计关键点以及变频工作对发电系统的影响;进一步针对变频交流起动发电机新增的起动功能,重点分析起动工作时励磁机的两种工作方式,并给出建议的工作方式。通过分析现有变频交流起动发电机及其起动发电系统,指出进一步提高其功率密度和效率是完全可能且必要的,从而为其在中国未来大型客机上的应用和发展提供参考与建议。The variable frequency Alternating current(AC)generator is developed on the three-grade constant frequency AC synchronous generator and the wide range of work speed brings new features to the variable frequency generator system.Furthermore,the variable frequency AC starter/generator system is developed on the variable frequency AC generator and it is more complex in terms of its working condition and working characteristics.This paper first introduces the structure characteristics of the variable frequency generator,and then the key points of the design and the impact of variable frequency on the generation system are presented.After that,the start working mode of the variable frequency AC starter/generator is studied and the two exciter operation modes are investigated.The results show that the transformer operation mode is suggested.At last,through analyzing the current variable frequency AC start generator and its generation system,this paper points out that it is possible to further improve its power density and efficiency,and the work will promote its application to the large civil aircraft in our country.
