Fault analysis using alienation technique for three-terminal transmission line
2018 2nd International Conference on Power, Energy and Environment …, 2018•ieeexplore.ieee.org
In this paper, application of alienation technique has been presented for fault analysis on
three-terminal transmission line system. For evaluation of Alienation Coefficients, samples of
post-fault differential current (of successive cycles), are compared, for a quarter cycle
window. This Alienation Coefficient is compared with the threshold, to detect and classify the
faults. The proposed protection scheme is able to detect and classify the faults, within
quarter-cycle. The performance of the proposed scheme has been established by case …

For evaluation of Alienation Coefficients, samples of post-fault differential current (of successive cycles), are compared, for a quarter cycle window. This Alienation Coefficient is compared with the threshold, to detect and classify the faults. The proposed protection scheme is able to detect and classify the faults, within quarter-cycle. The performance of the proposed scheme has been established by case studies, in which fault locations, incipient angles and impedances are varied.
