Use of genetic algorithms (GA) for optimal coordination of directional over current relays

2012 Students Conference on Engineering and Systems, 2012
In this paper, the optimization of coordination of directional overcurrent relays in an interconnected power system is presented. The objective of protective relay coordination is to achieve selectivity without sacrificing sensitivity and quick fault clearance time.

An improvement in coordination of distance and over current relays for DERs connected power networks

2015 Annual IEEE India Conference (INDICON), 2015
Distance relays are set in coordination with the over current relays for protection of transmission power lines. Depending upon the location of faults on the transmission lines, faults are cleared by the distance relays from zone-1 or zone-2. If the distance relays fails due to any relay failure reasons.

A new hybrid particle swarm optimization for optimal coordination of over current relay

2010 International Conference on Power System Technology, 2010
Directional over current relays (DOCRs) coordination problem is a nonlinear and nonconvex problem which has many constraints. Optimal coordination of over current relays has been usually solved using linear and nonlinear programming. Also genetic algorithm and particle swarm optimization methods are used to fined the optimal solution of the problem. In

Optimal Coordination of Directional Over Current Relays in Power System Using Genetic Algorithm

Proceedings of the 41st International Universities Power Engineering Conference, 2006
In this paper a new approach will be used for optimal coordination of directional over current (DOC) relays based on genetic algorithm. In this approach, optimal operation characteristics and also optimal current setting and time setting of each OC relays will be determined simultaneously.
