Wind site elevation and tower height effect on short circuit current of DFIG

摘要

The use of doubly fed induction generator (DFIG) in large wind turbines has become quite common over the last few years. But the main disadvantage of DFIG is that it's very sensitive to grid disturbance, such as short circuit and voltage dip. It could cause over current in rotor and stator windings. This paper investigates the effect of wind turbine altitude and height of tower on short circuit current.
