Protection Of Power System By Optimal Co-ordination of Directional Overcurrent Relays Using Genetic Algorithm
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2012, Vol 2, Issue 1
Abstract
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. A methodology is adopted for the consideration of backup relays in the optimal coordination of directional overcurrent relays. The calculation of the Time Dial Setting (TDS) and the pickup current (Ip) setting of the relays is the core of the coordination study. The objective function to be minimized is defined as the sum of the time dial settings of all the relays. The inequality constraints guarantee the coordination margin for each primary/backup relay pair having a fault very close to the primary relay. Using this formulation, the size of the optimization problem is significantly reduced. Genetic Algorithm is the algorithm being applied to minimize the operating times of the relays. Both Linear and Non Linear Equations are framed for the test bus system used and optimized using the Genetic Algorithm in this paper.
