Reliability Assessment of 132 kV Ikorodu Transmission Sub-Station, Nigeria

Abstract
In this paper, the reliability performance of 132 kV feeders in Ikorodu Transmission substation located in Ikorodu, Lagos was assessed using statistical method. The daily outage data of the feeders for six months were collected and probabilistic approach was used to determine the reliability of the substation using indices such as availability, reliability, mean time to repair, mean time before failure, and failure rate. Results obtained from the study during the period under investigation showed that the reliability of the industrial feeder performed better than the other feeders with a reliability of 74.27%, and availability of 93.9%. Hence, this paper proposes a star bus topology arrangement of the transmission line feeders for improvement of the reliability of the network. This will ensure that a fault in a given feeder cannot totally prevent consumers from accessing electricity as consumers can access alternative feeders.

Key words: Reliability, Tree topology, Transmission feeders, Switch gears
