Abstract

Rapid location of faults in electrical distribution system is very critical for effective and efficient operation. The operation of the power system must be reliable and as economical as possible. The persistent lingering of fault conditions in the distribution networks is the lack of efficient technology to locate the faults in the distribution network and lack of proper maintenance of the equipment in the network. Most of the accidents caused to individuals (either the consumers or the workers) in this distribution networks are caused by some of these faults that not easily identified. This research proposes a model to locate faults in a distribution network using an enhanced impedance-based method for fault location. The model was simulated on the 2nd Avenue 11 kV feeder (Lagos) with the use of one-end impedance-based method. The results show a little marginal error when the location values obtained with the model are compared to doing physical inspection on the distribution line. The parameters that could affect the effectiveness of the method were analyzed.
