Reliability Evaluation of Ayede 330/132KV Substation

Reliability is an analytical tool used to measure the ability of a power system to perform a function when required for a specified period of time in particular environment and conditions. Reliability analysis is a vital tool for critical identification of sensitive components of the electrical power systems that need more attention for better improvement and at the same time to increase the system availability. The aim of this research work is to carry out reliability assessment of electrical power system by using some reliability indicators. Hence this work presents a research on reliability assessment of 330/132KV substation by using Ayede 330/132KV substation as a case study. Ayede 330/132KV substation feeds six different 132/33KV substations, such as Jericho, Ijebu ode, Ibadan North, Sagamu, Ayede and Iseyin. In this study different parameters that determined optimum operation of a power system such as SAIDI, CAIDI, SAIFI, CAIFI, CIII, MAIFI and ASAI were deduced.
