This paper describes different cases of parallel transmission lines and analyzes some well known application problems associated with their protection. Distance protection performance problems are in the focus due to the fact that they are the most commonly used protection type for parallel transmission lines. The behavior of ground overcurrent protection on double circuit applications is also discussed in the paper. Finally, some advanced features of communications assisted schemes, non-communications protection schemes and fault location for double circuit lines are discussedread more

Unsynchronized fault location based on the negative-sequence voltage magnitude for double-circuit transmission lines
Behnam Mahamedi,Jianguo Zhu +1 more
TL;DR: In this paper, the authors proposed a new approach to fault location for double-circuit transmission lines based on only the voltage data of both ends of the faulted circuit, where the ratio between the magnitudes of negative-sequence voltages measured at both ends is utilized to estimate the fault location.

Directional relaying for double circuit line with series compensation

Accurate fault location technique for power transmission lines
A.T. Johns,Sadegh Jamali +1 more
TL;DR: In this article, the authors describe a very accurate fault location technique which uses post-fault voltage and current derived at both line ends, independent of fault resistance and the method does not require any knowledge of source impedance.

Cross differential protection of double lines based on supper-imposed current
TL;DR: The cross differential protection has been more and more widely used to protect parallel double transmission lines in power systems since it can operate without time-delay and does not need communication link.
