DESIGN OPTIMIZATION AND ENVIRONMENTAL IMPACT STUDIES FOR THE ITAIPU± 600 kV HVDC LINES AND ELECTRODE LINES
(1981)
Zusammenfassung
The Itaipu Transmission System will transmit
12600 MW over a distance of 900 km. ( 1) Both EHV alternating
current (800 kV) and HVDC (± 600 kV) will
be utilized. The studies of the :': 600 kV HVDC line
design completed in 1980 are discussed. As the Itaipu
System will employ HVDC transmission lines for
the first time in Brazil, the design studies concentrated
on the interaction of the lines with their
physical and electro-magnetic environments to de -
monstrate that HVDC lines would not cause any great
disruption than known and accepted for EHV ac lines.
The electro-mechanical design studies, which resulted
in differences between the HVDC line designs and
EHV ac lines, are summarized. Studies of the influence
of electro-magnetic interference, electric
fields, corona phenomena, and insulation coordina -
tion on the line design are described. Studies of
the electrode line design with particular emphasis
on insulator string arc conditions are also repor -
ted. Final results of the studies are presented in
the form of design criteria and a description of the
line configuration.
