摘要 针对小型单相同步发电机负载运行时电压波形正弦畸变率大的问题,采用场路耦合时步有限元法建立了小型单相同步发电机的模型,编程计算了发电机在额定负载下,阻尼绕组应用不同连接形式和选用不同材料时的电磁场,比较了各种情况下的电压谐波含量大小,分析了小型单相同步发电机中阻尼绕组的作用。结果表明小型单相同步发电机中阻尼绕组可以削弱负序磁场的影响,降低电压波形正弦畸变率;阻尼绕组采用不同连接形式和选用不同材料对负序磁场的削弱程度不同,其中起主要作用的是阻尼绕组的连接形式。 To solve the problem of voltage waveform distortion of small single phase synchronous generators （SSPSG） when operating with loads, a method of time-stepping finite element coupling with circuits is used to model the SSPSG and compute the SSPSG electromagnetic field with different damper winding connection types and using different damper winding materials when carrying rated loads. The voltage harmonics of each condition are compared and the influences of the damper winding analyzed. The results indicate that the SSPSG damper winding can weaken the negative sequence magnetic field in SSPSG, decreasing voltage waveform distortion. The damper winding connection manners play a much more important role than that of winding materials on weakening the negative sequence magnetic field in SSPSG.
