Description
About 80% of faults in the power system distribution are earth faults.
Studies to find effective methods to identify and locate faults in distribution
networks are still relevant, in addition to the presence of harmonic signals
that distort waves and create deviations in the power system that can cause
many problems to the protection relay. This study focuses on a single
line-to-ground (SLG) fault location algorithm in a power system distribution
network based on fundamental frequency measured using the differential
equation method. The developed algorithm considers the presence of
harmonics components in the simulation network. In this study, several
filters were tested to obtain the lowest fault location error to reduce the
effect of harmonic components on the developed fault location algorithm.
The network model is simulated using the alternate transients program
(ATP)Draw simulation program. Several fault scenarios have been
implemented during the simulation, such as fault resistance, fault distance,
and fault inception angle. The final results show that the proposed algorithm
can estimate the fault distance successfully with an acceptable fault location
error. Based on the simulation results, the differential equation continuous
wavelet technique (CWT) filter-based algorithm produced an accurate fault
location result with a mean average error (MAE) of less than 5%.
