A stable and reliable electric power supply system is an inevitable pre-requisite for the technological and economic growth of any nation. Due to this, utilities must strive and ensure that the customers are getting the reliable power supply. In this thesis the reliability of Wukro Distribution System was done on 15kV system to assess the performance of the existing system. The installation of Autorecloser and distributed generation in strategic places reduces the outage time in case of abnormal conditions and improves the reliability of the network. This alternative which gives low system average interruption duration index (SAIDI), system average interruption frequency index (SAIFI) and customer average interruption duration index (CAIDI) are being assessed and considered. The reliability analysis indicated that of 15kV of Wukro town feeder could be further improved by installation of optimal placement of Autorecloser and distributed generation; ETAP software simulation has also been used for both initial optimal network configurations. Simulations of reliability analysis without any mitigating device has been conducted and SAIDI, SAIFI, ASAI, ASUI, AENS and CAIDI of the system are examined. As indicated in this simulation SAIFI and SAIDI becomes 420 f/customer and 380 hr/customer respectively that is more far away from the accepted reliability standard. As the result of integrating 2 reclosers and one DG the reliability indexes have improved greatly and their percentage improvements for SAIDI, SAIFI, AENS, and ASUI are 49.5%, 48.1%, 53.7%, and 49.45% respectively which is better in comparison with the existing reliability indices. Thus, because of the integration of smart devices, network reliability indexes have changed dramatically and this change has great contribution to the city‘s entire network reliability enhancement.
