This configuration design, shown in Fig. 4, considers an offshore
grid in which all wind turbine strings are connected to a common
offshore collection point. The present scheme differs from DC1 in
the connection to the main offshore platform, since such collector
grid includes an intermediate offshore platform gathering the inter-
array cables from the feeders. Export cables with higher crosssection
are used to interconnect the intermediate platform with the
main offshore substation, where, as in the previous case, a DC/DC
converter is installed
