factors affecting the decision to refurbish hvdc and fActs installations. the article shows how unique
power electronics systems in original installations often have many
individual design features and constraints. the refurbishment process

must be addressed with that particular system and owner in mind.
✔ "Keeping the power flowing:
A commitment throughout the
hvdc and fActs life cycle"
emphasizes the need for ongoing maintenance and the need for

refurbishments. facilities located in
europe and Africa are discussed as
examples of maintenance upgrade
strategies, including hvdc midlife
and partial upgrades, control and
protection upgrades, and thyristor
valve upgrades.
✔ "Refurbishments in Australasia:
Upgrades of hvdc in new Zealand and fActs in Australia"
further extends the geographical diversity in this issue. proper
planning for the refurbishment of
an hvdc facility addressed high
seismic design requirements, met
switchyard constraints, and maintained the supply of the existing
hvdc link during the construction
of the new pole. the use of a mobile static var compensator (svc)
provides an innovative approach
to refurbish multiple svcs with
minimum outage time.
the "in My view" column, by lionel
o. Barthold, Dennis A. Woodford, and
Maryam salimi, is the prime example of
everything old is new again. lionel, who
will be 90 years young this month, and
his coauthor Dennis have been longtime
mentors to many of us in the electric
power industry. they collaborated with
Maryam, who is in an earlier stage of
her career, to discuss dc supergrids, dc
storage, and some of the benefits and requirements of a dc-dc transformer.
