| Abstract: | The space-vector was used as a kind of mathematic tool to analyze the transient course of doubly-fed induction generator (DFIG) during three-phase short-circuit 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. |
