RESUMO:

This work proposes the development of one-terminal traveling wave-based transmission line
protection methods for HVAC (High Voltage Alternating Current) and HVDC (High Voltage
Direct Current) systems. The effect of the sampling frequency on the protection is considered,
which until now has not yet been investigated for one-terminal methods. Inaccuracies on the
wave velocity estimations, which classically yields to problems on methods based on traveling
waves, are addressed and solutions to such problem are presented. The preliminary results
related to the proposed one-terminal protection method for HVAC transmission lines show that
the proposed function, when associated with other existing protection functions, can achieve
a quite remarkable enhancement for the dependability and velocity of the transmission line
protection.
