| 摘 要： | 介绍了一种混合励磁永磁同步发电机的电磁场有限元分析，这种发电机的主发电机部分和一般的永磁同步发电机相同，样机采用了表面径向式磁钢转子，另有用于调节电压的辅助电励磁部分，两部分共有一套电枢绕组。为了精确计算该发电机的参数和特性，采用了电磁场有限元计算，特别是对磁场分布比较复杂的电励磁部分采用了三维电磁场分析，在有限元数值计算的基础上，推导了计算发电机外特性的等效电路，并加工了实验样机，样机实测数据和计算结果相吻合。 |

| Abstract: | An analysis of a novel structure hybrid excitation synchronous generator(HESG)was presented,which consisted of a permanent magnet part as the major component,and an electrically-excited part as the assistant component,and hence possessed the advantages of both the PM and electrically-excited generators.To accurately determine the machine parameters,three-dimensional(3D)finite element analysis was conducted to solve the magnetic field distribution in the electrically-excited part,which was quite complicated and 3D.An equivalent electrical circuit was derived to calculate the generator performance,such as the external characteristic or the relation between the output voltage and the load.A hybrid excitation PM synchronous generator prototype has been constructed and the experimental results validated the theoretical calculations. |
| Keywords: | hybrid excitation permanent magnet synchronous generator magnetic field finite element analysis external characteristic |
