| 摘 要： | 小型单相同步发电机在负载时输出电压中谐波含量大,阻尼绕组可以削弱它在负载运行时的负序磁场,降低电压波形正弦畸变率。本文采用场路耦合时步有限元法编程计算了小型凸极单相同步发电机额定负载时的电压波形,计算结果与实验结果接近,证明了该计算方法及所编程序的正确性。详细分析了阻尼绕组的不同连接方式及材料对电压波形的影响,所得结论可以为阻尼绕组形式及材料的选取提供理论指导,用以提高电压波形质量。 |

| Abstract: | The small salient pole single phase synchronous generators(SSPSPSG) are used widely as standby power supply,but they have heavy harmonic distortion in their voltage waveform with load.The damper winding can weaken the negative sequence magnetic field in SSPSPSG with load and decrease the voltage harmonic distortion.In this article,time-stepping finite element method coupling with circuit is programmed and used to compute the output voltage of the SSPSPSG on rated load.The results of computation are consistent with the tests,which show that the computation method and program are both correct.The voltage waveform of SSPSPSG with different connection manners and different materials of damper winding are analyzed in detail.The conclusion can provide theoretical guide for selecting connection manner and material of damper winding and lead to the improvement of voltage waveform. |
| Keywords: | salient pole single phase synchronous generator damper winding voltage waveform time-stepping finite element method coupling with circuit |
