 en Reliability Assessment of a Gas Generating Station in Ogun State, Nigeria


This study evaluates and presents the reliability and availability of a power plant, Akute Power Plant, Ogun State, Nigeria, during the period of January – December, 2015. Time series load data on each generating unit were collected from Akute Power Plant daily operational log book from January to December 2015. Outages were classified into types, frequency and durations. The operational data for the above period was collected and analyzed using Reliability methods. Reliability conditions are defined with the collected data and types of the failure faced by each generating units. The most important reliability indices like mean time to repair (MTTR), mean time to failure (MTTF), mean time between failures (MTBF), repair rate (µ), failure rate (λ) were determined based on the loss of load approach. The reliabilities of each generating unit were evaluated on monthly basis for one year and the average availability of G1, G2, G3, and G4 were 0.9701, 0.9726, 0.9767, and 0.9707 respectively, while the reliability indices for G1, G2, G3, and G4 were 0.9860, 0.9880, 0.9854, and 0.9840 respectively. Suggestions were made to minimize system unavailability in order to improve the reliabilities of the network.
