Reliable power system protection requires the co-ordination of protection devices for all types of fault and network loading and topology states. Operation of protection devices must ensure:
- Reliability, selectivity, dependability and security
- Elimination of nuisance relay tripping
- Optimal relay setting
- Inclusion of different relay co-ordination philosophies.
NEPLAN Protection Assessment helps utilities make sure that all the above aspects are respected in order to automatically assess the protection of their power system.
NEPLAN Protection Assessment is addressed to large transmission and distribution utilities that need to have a reliable protection system ensuring proper selectivity and sensitivity for all relay settings.
It provides automatic assessment with clear indication of relays that are not selective and faults that are not cleared.
