摘　　要：针对自激感应发电机（self-excited induction generator，SEIG）独立系统，采用判断系统稳定性的复系数Hurwitz判据进行空载与带载建压分析。基于两相静止坐标系下SEIG的暂态等值电路，写出系统状态方程，利用复系数Hurwitz判据分析了SEIG自治系统稳定的充要条件，并计算得到SEIG空载与负载建压的临界参数值，样机实验验证了计算结果的正确性。以SEIG的自激建压过程为例，证明了将复系数Hurwitz判据应用于SEIG的暂稳态分析的可行性。所得到的结论为Hurwitz稳定性判据进一步应用于SEIG的稳定性分析打下了基础。In view of the self-excited induction generator （SEIG） isolated system, the complex Hurwitz stability criteria was used to analyze its voltage build-up performance with and without loads. The state equations of SEIG were established based on the transient equivalent circuits under a static reference frame. The sufficient and necessary conditions for the stability of the SEIG, which was taken as an autonomous system, were given by complex Hurwitz stability criteria. And the critical parameters of voltage build-up of SEIG with and without loads were calculated. The results were verified to be correct compared with the experimental ones. Based on the self-excited voltage build-up process of SEIG, it is proved to be feasible to apply the complex coefficient Hurwitz criteria to the transient and steady stability analysis of SEIG. The conclusions of this paper lay a foundation for further applications of the complex Hurwitz criteria in SEIG stability analysis.
