Acaray. They then detail a comparative
analysis of plant-modernization options
developed in collaboration with the utility. Both power generation planning and
asset-management models were considered. Various pieces of data and information were collected and added to the
model, including hydrological data, unit
efficiency information, environmental
impact, and load projections. The model
allowed for an ideal modernization option to be selected using risk-based
capital expenditure optimization.
The last hydropower-themed article is by Peter Donalek. The article
begins with a history of hydropower
and pumped storage in particular, with
a special focus on the Rocky River
plant (completed 1928), the first of its
kind in the United States. The author
details how hydro storage units may be
converted to pumped storage. A reversible motor/generator and pump/turbine
on a common shaft at Hiwasee Unit 2
is cited as an example, along with
solid-state variable frequency converter inverters. The synergies between
pumped storage and nuclear generation
are described. The technologies related
to efficient, adjustable-speed pumped
storage turbines are outlined. The author then discusses the experiences
of Japanese utilities using adjustablespeed machines to provide frequency
regulation. The article concludes with
a discussion of doubly fed induction
machine-pumped storage units and an
overview of new pumped storage technologies under development.
The "In My View" column, written by Girish Behal, provides a view
on how current developments in hydropower will shape its future growth.
The current status of large-scale hydropower development is outlined. New
small-scale hydropower technologies
are featured, including closed-loop
projects on existing impacted sites,
small-scale storage development, the
conversion of existing dams for power
generation, and modular construction
technology for distributed hydropower.
We anticipate that future development
of large-scale hydropower generation
will slow down, but there will be sig-
