ABSTRACT
Retbiliry indices ore considered to be remonabk md logic wuys to judge the
perfirmame of rm electric power tystem ReliabiIi~in dices which m proposed by the
IEEE are used ra evaluate the perfmmce of selected distribution.~stemo n the natlonai
grid. Ten yems of outage data (1998 - 200 7) from seven selected disi?ibwtl'on systems on
the national grid were wed as case studies in this resewch work. A generalized model is
developedf or a qsrantimive evalucrti~nof relative indices of the nationd grid ?stem. nte
development of the model stated with identffcation of the system reliabiliv indices and
estimuting the contributions ojsystem indicd to the failure rate of the selected distribution
system on the national gri'd. The computed qvstem reliability indices we used as input
paranietms for the generalized modd ReIative CADI inda is computed by simulation
using ,'KATM 7.7 which automatically generates the graph of &k reidbe CAWI against
names of feeders. The percenmge averuge relafive CAIDIs fir Ibudun, Port-Hmcowt and
Benin distribution system are 71.86%, 52.79% and 75.79% rsspectively, thus, merage
rztiabiliry levels. Rorin, Lkeja Kaduna and Kano dhkibution system have percentuge
average relative CADIS of 11.93'%, 39.76%, 440.1 7% and 41 -08% respechirely with poor
reliabiIitJl levels. With the ald of curve jtting (cj mls, hue distinct model equations were
developedfrorn which a genwalid model is formulafgd for a qarantitutive evaluati~no f
