摘要
励磁系统是无刷交流同步发电机的重要组成部分,对发电机的各项性能具有重要影响。目前,可控相复励励磁、三次谐波励磁和永磁副励磁机励磁三种励磁方式应用广泛。通过将发电机励磁系统结构图与原理图相结合的方法,对三种励磁方式的结构组成与工作原理进行了详细阐述和定性分析,梳理归纳了各自系统的优缺点,得出了三种励磁方式各自所适用的发电领域。
Excitation system,as an important part of the AC brushless synchronous generator,has great influence on its performances. At present,controllable phase compound excitation,third harmonic excitation and permanent magnet sub-exciter excitation are widely applied. A detailed explanation and qualitative analysis was made on the structural composition and working principle of these three excitation modes through a combination of the structural drawing and schematic diagram of the generator excitation system. On this basis,their respective advantages and disadvantages were summarized. Finally,power generation fields to which these modes might be applied were obtained.
