Abstract:
Electricity networks are, and will continue to be a critical part of Nigeria's energy infrastructure with the assurance of consistent maintenance. It therefore becomes necessary to evaluate the causes of electric power consumers' dissatisfaction using Asaba 33kV feeder as a case study. The objective of this project is to evaluate and develop a framework for reliability analysis of Asaba 33kV feeder using Fault Tree Analysis (FTA) employing OpenFTA software. Data used were collected from daily fault logbook of Benin Electricity Distribution Company Asaba Business District for a period of five years, as well as from the Regulatory Agency. The OpenFTA simulation results show the number of primary fault events deduced to be twenty-four however, only four of these twenty-four primary fault events account for over 80% of the total network failures (Consumers' Dissatisfaction). The validity of the results indicates the appropriateness of FTA on electricity distribution networks..
