Abstract
The relevance of multi-terminal HVDC grids is
expected to increase in next years. However, there are still several
technical, economical and legal limitations that interfere with the
construction of those multi-terminal links. One of the main
technical obstacles is the handling of DC fault currents, because
the interruption of DC currents in HVDC systems is nowadays a
challenge. Among other proposals, the application of
Superconducting Fault Current Limiters (SFCLs) combined with
a mechanical Circuit Breaker (CB) solves technically that issue,
according
