Summary: | This study deployed the analytical technique and assesses the reliability of the Nigerian electricity distribution system with the Sabon-Gari distribution substation in Kano State as a case study while considering the performance of each component of the substation. Data on daily outages on the feeders from January to December 2015 were collected from the substation logbooks and analysed to obtain the system reliability indices. The SAIDI, SAIFI, CAIDI and ASAI for the substation were 0.8905, 0.9823, 10.9008 and 0.9027 respectively. These values when compared with those of Denmark, the Netherlands and even Kenya were much higher (except for Kenya that reported a higher CAIDI) and therefore unacceptable. This paper recommends improvement in the substation reliability indices by adopting renewable energy technologies to reduce the present over-dependence on conventional energy resources, use of micro-grid in the remote/rural areas to lessen the stress on the national grid, automation of the entire network to facilitate the resolution of faults, implementation of smart distribution grid as well as timely/routine inspection and maintenance of distribution lines. The outcome of this study would be useful to system engineers tasked with substation design, operation and maintenance processes. |
