N2 - Distance relays mal-operate for transmission lines connected to type-3 Wind Farms (WFs). This paper proposes a waveshape property based protection of the intertie zone between wind farm and grid during 3-phase faults. It mitigates the challenges faced by the normally used distance relays and ensures the protection systems' security and dependability. The proposed scheme uses the auto-regressive coefficients of the 3-phase currents obtained from the Current Transformer at one end to distinguish the faults fed by the type-3 WFs and the primary grid and determines the fault zone accurately. PSCAD/EMTDC is used to verify the validity of the technique on three test systems. The results obtained with different wind speeds, crowbar resistance, fault resistance, inception time, and fault locations are encouraging and suggest the possible utilization of feature-based algorithms to improve the power system distance relaying system. In addition, the protection scheme can be utilized for lines compensated with series capacitors and phase shifting transformers.
