Abstract

Calculation of short circuit current is an important task for wind farm and power system. In this paper transient of DFIG is analyzed under short circuit condition, and the theorem of constant flux linkage is applied to determine short circuit currents in the synchronously rotating reference frame dqo. Then, transient response of different order models considering or ignoring this theorem is obtained and compared. The effect of rotor voltage and rotor resistance on stator over-current is simulated too.
