Abstract	This work proposes the analysis of three-phase short circuit on doubly fed induction generator, DFIG. This generator is again a subject of study for hydrogeneration as per recent investments on variable-speed Pumped Storage Power Plants. This configuration, which allows asynchronous shaft speed, is also an alternative for conventional hydro power plants, providing improvements on energy efficiency and stability and optimization of power system. Current studies on this subject are focused on wind power applications, covering mostly control and generation optimization aspects while there aren’t so many studies on short-circuit especially with analytical solution. Electrical transient studies are usually covering voltage dips or sags on transmission line and associated methods to maintain power unit connected to power system during such. The researches on hydro power are also about control, operational optimization and power system improvements when DFIGs are installed. Thus, it is necessary to contribute to research regarding behavior of such generators under electrical transient conditions, more specifically under short circuits. The analytical equation for three-phase short circuit was developed as well the electric model based on the one proposed by Krause (KRAUSE, 2002) for simulations on Simulink of Matlab.
