This paper analysis the applicability of distance relays with measuring impedance for wind farm transmission lines. Distance relays with measuring impedance are only related with the impedance parameter of transmission lines. Hence, the distance relays are suitable for wind farm transmission lines. However, due to the transition characteristics of wind farms, the tolerance transition resistance ability of distance relays is seriously reduced. RTDS digital-analog hybrid simulation studies verify this conclusion.
