This paper proposes a distance relay in time domain based on the R-L differential-equation algorithm which is suitable for wind power integration system. However, the conventional R-L differential-equation algorithm cannot detect the correct fault direction if the fault point is very close to the relay location.
The number of connected wind farms has triggered an increase of power transferred by the HV lines. As far as the functioning of distance protection is concerned, this leads to the increase of the admitted load of HV lines and brings closer the operating and admitted load characteristics.
In terms of integrating large-scale wind farms into power systems, the fault characteristics of power systems have undergone fundamental changes, potentially leading to the rejection and misoperation of traditional protections. To address these issues, a time-domain pilot protection based on trajectory distance characteristics is proposed.
These parameters are dependent on the number of operating wind turbines, distance from the ends of the line to the WF connection point (point M in Fig. 12a), fault location and the time elapsed from the beginning of a fault (including initial or steady fault current of WF).
A source of problems for distance relays on the Wind Farm MV system is the inclusion of a current-limiting im-pedance in the neutral of the source transformer. The voltage drop across this impedance during earth fault conditions affects the voltages seen by the distance protection both in faulty but as well in the healthy phases.
A novel three-phase fault direction identification method for distribution systems with DFIG-based wind distributed generation was proposed in . The decaying pattern of the ac component for DFIG fault currents was used as the feature in discriminating fault directions. However, this proposed method can be only used during balanced faults.
