Abstract
This dissertation is primarily concerned with the generating
plant maintenance scheduling problem of an electric utility in
a developing environment as typified by the generating facilities
of National Electric Power Authority (NEPA). The importance
of this study lies in the fact that system reliability and
operating cost of such electric utility are significantly affected
by the adhoc maintenance philosophy adopted. There is the need
to evolve an efficient maintenance policy aimed at optimizing
system reliability and security.
In this research effort, therefore, the maintenance scheduling
problem has been recognised as an optmization problem with
several constraints. Although the mathematical formulation is
not altogether new, its application via existing optimizing
algorithms to solve specific maintenance scheduling problem
often requires some innovative assumptions to be made in order to
generate realistic maintenance schedules. Herein, the Engineering
assumptions and approximations made with respect to the
maintenance problem at hand simplified the optimization problem
proposed and led to the development of versatile software program.
This technique has been applied to twenty eight generating units
of NEPA, based on a scheduling horizon of one year and a
maintenance period of one month. Several case studies were ran and the
results obtained have been presented and fully discussed.
