摘　　要：从凸极同步发电机设计方法出发,设计了凸极同步发电机主要参数。从气隙更改为不均匀气隙、优化转子阻尼孔间距、优化极弧系数、对比节距等几个方面,对同步发电机磁场、线电压以及波形畸变率进行研究分析。提出了利用有限元分析软件,对凸极同步发电机波形畸变率进行优化的步骤和方法。Based on the design method of salient pole synchronous generator,the main parameters of salient pole synchronous generator are designed.The magnetic field,line voltage and waveform distortion rate of synchronous generator are studied and analyzed from the aspects of changing air gap to non-uniform air gap,optimizing rotor damping hole spacing,optimizing pole arc coefficient and comparing pitch.The steps and methods of optimizing the waveform distortion rate of salient pole synchronous generator using finite element analysis software are proposed.
