ABSTRACT: This paper presents the main results on the use of
conventional protection hardware to protect a Half Wavelength Transmission
Line, or shortly AC-Link, for possible occurrence of three-phase and
single-phase fault during energization maneuver. Lines of these dimensions do
not exist today, but in countries of continental size they could be an interesting
alternative to HVDC transmission, since the AC-Link has less dependence on
Power Electronics technology. The studies on performance and relay settings
were implemented using the RTDS real-time simulator. It is important to note
that the AC-Link protection for the energization maneuver can be performed with
existing hardware on conventional relays.
