The integration of renewables into power systems introduces several technical challenges including the development of appropriate models for system protection studies and accurate evaluation of short circuit contributions. Converter-interfaced wind turbines (WTs) produce significantly different current waveform signatures compared to the traditional synchronous or asynchronous generators. This paper proposes a new phasor domain modeling approach for Type III WTs with doubly fed induction generators using the concept of control-based equivalent circuits. The proposed model accounts for the impact of negative sequence quantities on the WT control response to achieve accurate simulation of unbalanced faults.
