Overcurrent relay coordination with different penetration in distributed generation

Power distribution network is suspected to performance degrading factors alike load fluctuation which trigger the power losses. In order to substitute the losses in distribution network; known amount of power is being injected directly into load through using of distributed generators (DGs). This al...

Electronics Nuclear engineering Power distribution network is suspected to performance degrading factors alike load fluctuation which trigger the power losses. In order to substitute the losses in distribution network; known amount of power is being injected directly into load through using of distributed generators (DGs).

Prolonged fault clearance time is one of the negative correspondence of relays miscoordination.
