摘　　要：利用空间矢量作为数学工具对双馈发电机机端短路故障的暂态过程进行了解析分析。根据发电机电磁基本关系,推导出故障电流,电磁转矩以及磁链暂态分量衰减时间常数的近似计算公式。The space-vector was used as a kind of mathematic tool to analyze the transient course of doublyfed induction generator （DFIG） during three-phase shortcircuit fault at its terminal. According to the electromagnetic relationship of DFIG, the analytic expressions of fault current, fault electromagnetic torque and flux-linkage transient time constants were derived.
