Enhancing Accuracy While Reducing Computation Complexity for Voltage-Sag-Based Distribution Fault Location

A fault-location method for radial distribution systems is proposed in this paper. The proposed method uses voltage and current phasors from feeder root and voltage sags measured at sparse nodes along the feeder, and pinpoints faults to the nearest node. Decision-tree (DT)-based fault segment identi...
