Adaptive Distance Protection for Microgrids [PDF]
IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015 Due to the increasing penetration of distributed generation resources, more and more microgrids can be found in distribution systems. This paper proposes a phasor measurement unit based distance protection strategy for microgrids in distribution system ...

Calculation of specific operating modes of relay protection for AC traction networks
Вестник Научно-исследовательского института железнодорожного транспорта, 2020 Relay protection of traction networks against short-circuit currents in alternating current sections should have both selectivity and speed. However, in areas with an increased probability of burnout of contact wires during a short circuit, selectivity ...

Mutual Coupling Compensation Techniques Used for Distance Protection of Parallel Lines
Energies, 2021 When a distance relay protects a transmission line located on a dual circuit tower, a coupling effect will occur between the two circuits. Transposition of the circuits can reduce the mutual impedances, but this does not cater to the zero-sequence mutual
