Directional Overcurrent Relays Coordination Problems in Distributed Generation Systems [PDF]
Energies, 2017 This paper proposes a new approach to the distributed generation system protection coordination based on directional overcurrent protections with inverse-time characteristics. The key question of protection coordination is the determination of correct values of all inverse-time characteristics coefficients.
