摘　　要：本文阐明了双轴励磁同步发电机（ｄ．ｗ．ｒ）的动态稳定性的分析方法和所得到的结论。与常规绕制转子（ｃ．ｗ．ｒ）汽轮发电机的特性相比较，ｄ．ｗ．ｒ发电机能够不改变转子磁通相对于气隙磁通的位置，满意地控制有功和无功输出。在超前功率因数运行时，从空载到满载都能达到额定定子电流，并允许电压调节器增益在较大范围内变化，从而显著地提高了动态稳定极限。因此，采用ｄ．ｗ．ｒ发电机可供系统需要的发电设备和并联电抗器数目最少，带来明显的经济效益，具有极大的研究和应用价值。Dynamic stability analysis methods and results of synchronous machines with divided winding rotor have been illustrated in this paper.Comparing with conventional turbo generators,the generator with divided winding rotor can not change the rotor flux linkge position relatively with gas flux linkage,and control real and reactive power output satisfactorily.Under advanced power factor condition,they may arrive rating stator currents,and allow the gains of their voltage regulators to change widely.There fore,the their dynamic stability limits are augmented considerably.
