This work evaluates the response of DFIG-based wind turbine under voltage dips caused by transformer energizing. The transformer energizing is part of the normal operation of the power system and it can cause even-harmonic distortion, which could impact the operation of the power converters on the wind turbine. Previous works only considered voltage dips caused by electrical faults, then other causes should be understood to guarantee sufficient fault-right through of wind power installations. In order to address this study, voltage dips measurements with distinct magnitude, harmonic distortion and voltage unbalance are applied to a DFIG model. The impacts on the rotor current, on the DC-link voltage, and on the DFIG active power are analyzed.
