Impedance-Differential Protection: A New Approach to Transmission-Line Pilot Protection

IEEE Transactions on Power Delivery, 2015
Differential protection is able to provide the most selective protection compared with other protective schemes. In this paper, a new differential scheme is proposed for pilot protection of transmission lines. The concept of differential impedance ( ${\rm Z}_{\rm diff}$ ) is introduced using the synchronous voltages and currents of both terminals of
