OPTIMUM OVERCURRENT RELAY COORDINATION: A REVIEW

open access: yesThe Nucleus, 2014
In power system the protective relays are coordinated optimally to ensure that only the faulted zone of the system will be detached when the abnormal operating state will occur. The interconnected system as well as deregulated environment and increase in user demand force the utilities to implement optimally coordinated protection scheme to increase ...

The Control of Inverse Time-Overcurrent Relay by Ann (Artificial Neural Networks) for Automation of A System

open access: yes, 1998
Overcurrent relays can be used to protect practically any power system element. If the operating time of a relay depends on the current magnitude being smallest when the current is the greatest.

Considering Pilot Protection in the Optimal Coordination of Distance and Directional Overcurrent Relays

open access: yesIranian Journal of Electrical and Electronic Engineering, 2015
The aim of the relay coordination is that protection systems detect and isolate the faulted part as fast and selective as possible. On the other hand, in order to reduce the fault clearing time, distance protection relays are usually equipped with pilot ...
