| Abstract
|
Reliability and maintenance are well-known concepts, at least in a
colloquial sense, and one vaguely feels that the two are somehow
connected. The goal of this presentation is to establish this connection
and determine numerical relations between the two. This would allow for
meaningful comparisons of maintenance policies, and for maintenance
optimization to maximize reliability or minimize costs. The presentation
starts with reviewing the various kinds of maintenance policies.
Depending on the failure type, the required maintenance may be internal
or external; the present discussion concentrates on internal
maintenance. Next, distinction is made between regular (scheduled) and
"as needed" (predictive) maintenance policies, and also between
empirical routines and policies based on mathematical models.
Deterministic and probabilistic mathematical models are described, and
it is shown how maintenance and reliability can be linked in
probabilistic models. Two short numerical examples are presented; in
one, a probabilistic model is used to compare maintenance policies for
high-voltage circuit breakers. Finally, the relation between component
maintenance and power system reliability is discussed.

| Biography
|
John Endrenyi (M'59, SM'76, F'87, LF'94) is Principal Scientist Emeritus
at Kinectrics, Toronto (formerly Ontario Hydro Technologies), and an
Adjunct Professor at the University of Toronto. He received a Diploma of
Electrical Engineering from the Technical University of Budapest, the
MASc degree from the University of Waterloo (Ontario) and the Ph.D. from
the University of Toronto. After seven years of teaching and research in
Hungary, he joined Ontario Hydro's Research Division in 1959 where he
was first engaged in station and transmission line grounding studies
and, later, in the development of probabilistic models for power system
reliability. He has contributed to the methodology of power system
reliability and maintenance through numerous papers, seminars, a book,
and participation in several IEEE, EPRI, CIGRE and IEC committees. Dr.
Endrenyi is a registered Professional Engineer in the Province of
Ontario. (e-mail: john.endrenyi@kinectrics.com)
