Abstract:

Distribution network accounts for more than 90% of power service disruptions. This study presents faults occurring in the power distribution network using the Ogbomoso Business hub as a case study consisting of four feeders namely: Takie, Oke-Ado, Owode, and Gambari feeders. Simulation and Modeling were carried out using the MATLAB/Simulink software package. Fault data are obtained for selected feeders using a fault log book from the station under study. Analysis of fault is accomplished using MATLAB Software and associated with statistics measures (Distributed reliability indices). Reliability indices are therefore computed for each of the four feeders. The result shows that the Average Service Availability Index for Takie, Oke-Ado, Owode, and Gambari feeders are 99.884%, 99.843%, 99.888%, and 99.950% respectively.
