Description
Summary:This paper presents an adaptive transmission line protection scheme based on synchronized phasor measurement. This scheme uses the positive-sequence voltage and current phasors at both ends of a transmission line to determine the parameter of the transmission line and the location of a fault on the transmission line. This scheme can be used for the protection of both single-and double-circuit transmission lines. This scheme is also robust against power swing conditions. A novel adaptive single pole auto re-closer is introduced based on the proposed scheme due to its capability of differentiating transient and permanent faults. System simulation studies show that the proposed scheme is able to operate fast and accurately for transmission line protection.
