Coordination of adaptive distance protection in transmission and wind farm collector lines under resistive fault conditions [PDF]
International Journal of Industrial Electronics, Control and Optimization, 2020 Distance relays calculate the path impedance between the fault point and the relay location by sampling the voltage and current at the relay location. By using the ratio of the impedance estimated by the relay to the impedance of the line where the relay

The Effect of Wind Power Generation on Distance Relay Performance
Andalas Journal of Electrical and Electronic Engineering Technology, 2022 Wind Power Plants utilize induction generators to generate electrical power. This type of generator produces less short circuit current than synchronous generators; hence it may affect the operation of transmission line protection relays.

Mutual Coupling Compensation Techniques Used for Distance Protection of Parallel Lines
Energies, 2021 When a distance relay protects a transmission line located on a dual circuit tower, a coupling effect will occur between the two circuits. Transposition of the circuits can reduce the mutual impedances, but this does not cater to the zero-sequence mutual
