Maintaining system stability and power supply needs to have an efficient detection and fast elimination of faults

on transmission lines by the protection system. In order to clear transient single-phase faults on ...

Protection of power transmission has an important role in power systems. To have a better protection it is common to

combine difference types of relays, which combination of overcurrent and distance relays is a ...

Abstract—The directional overcurrent relays (DOCRs) coordination

problem is usually studied based on a fixed network

topology in an interconnected power system, and is formulated as

an optimization ...

To achieve better protection, it is common to use both

distance and overcurrent relays as main and backup relays

respectively, in power transmission protection scheme. In this

situation it is necessary ...
