RESUMO

Fault Indicator (FIs) devices have contributed to improve the location of faults on primary feeders, and consequently the reliability of distribution systems. However, one of the main problems facing their installation in a large scale in a distribution system is the lack of efficient methods to analyze big networks and to pinpoint exactly on which buses these devices should be placed. Thus, this paper proposes an evolutionary computing strategy to solve the problem of fault indicator placement in primary distribution feeders. Specifically, a genetic algorithm (GA) is employed to search for an efficient configuration of FIs, located at the best positions in the main feeder. The proposed methodology was applied in two actual distribution feeders. Technical and financial viability aspects are also analyzed. Finally, the results confirm the efficiency of the GA approach to the FI placement problem.
