  This paper proposes an accurate fault location algorithm technique based on
hybrid synchronized sparse voltage and sparse current phasor measurements. The
proposed algorithm addresses the performance limitation of fault location
algorithms based on only synchronized sparse voltage measurements (SSVM) and on
only synchronized sparse current measurements (SSCM). In the proposed method,
bus voltage phasor of faulty line or close to the faulty line and branch
current phasor of the adjacent line is utilized. The paper contributes to
improve the accuracy of fault location and deter the effect of CT saturation by
using hybrid voltage and current measurements. The proposed algorithm has been
tested on four bus two area power system and IEEE 14 bus system with the
typical features of an actual distribution system. The robustness of algorithm
has been tested by variation in fault location, fault resistance, load
switching. The simulation results demonstrate the accuracy of the proposed
algorithm and ensure a reliable fault detection and location method.
