aging power delivery infrastructures second edition pdf

In the long term, something between that “deliberate neglect” and the “intense
attention” plan will be closer to optimum. The important managerial points are that a
power system owner has a choice, that the sustainable point can be moved by making
changes in ownership and operating policies, and that the best ownership and
operating policies will change as a function of the age and condition of the equipment.
There is a wide range of sustainable points available to a utility depending on the
operating, maintenance, and loading policies it decides to put in place. What is best for
a new system may not be best for an older system. What works for one utility will
work for another, but perhaps not in the best possible way.

frastructure” must include more than just all the equipment. It must also include the
loading standards, operating guidelines, and inspection-maintenance-service and
refurbishment policies that the owner uses. Those standards and guidelines can
become deteriorated in their own way – obsolete with respect to current needs.

The aging infrastructure issues facing utilities and industry are about worn out equipment
and outdated designs and constricted sites and rights of way and outdated engineering
standards and operating procedures. Good aging infrastructure management consists
of optimizing the choice of equipment and its refurbishment while also making
compatible changes in all those operating and ownership policies, the whole
combination aimed at optimizing the business results the power system owner desires.

This book is composed of five major groups of chapters. The first consists of
Chapters 1 and 17, which together present an “executive summary” of the problem and
its major effects, the sustainable point approach, practical solutions that work, and the
limitations and consequences these have in the real world.

Chapters 2 – 6 provide a series of tutorial background discussions on topics
necessary to understand some of the subtleties of aging infrastructures and their
solutions. The third group of Chapters, 7 – 10, looks at various aspects of aging
equipment condition deterioration and its systemic effects, and how all that
interrelates with the many functions within a power system and an electric utility
company or industrial power system user’s business needs. Chapters 11 – 14 discuss
methods and technologies to measure, study, plan, model and decide how to best
manage aging equipment and the effects it creates.
