SIMULATION AND ANALYSIS OF FAULTS IN DISTRIBUTION NETWORK SYSTEM IN OGBOMOSO UNDERTAKING WITH DISTRIBUTION RELIABILITY INDICES

Abstract

Distribution network accounts for more than 90% of power service disruptions. This study present fault occurring on power distribution network using 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 MATLAB/Simulink software package. Faults data are obtained for selected feeders using 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 is 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
