ABSTRACT: In the present paper the main results of the
pre-operational studies related to the energization maneuver of a
Half-Wavelength Transmission Line (AC-Link), are presented. The simulations
were performed in PSCAD with actual Brazilian system data. Specifically the
following studies were performed: electromagnetic transient studies of energization
maneuver considering no fault and the occurrence of fault along the trunk;
dynamic analysis of generator units that will energize the AC-Link; TRV on the
circuit-breaker that will energize the trunk. The main conclusion is that the
AC-Link energization experiment can be implemented without jeopardizing or
causing time-life reduction of the equipment involved in the experiment, which
comprises the generator unit that will energize the trunk, the step-up
transformer, the arresters that will be kept during the experiments, as well as
the circuit-breaker that will energize and then trip the AC-Link.
