Abstract
With the advancement of technology, the electrical world has grown colossally through invention and optimization, hence adopting to the changing environment. With the arrival of power grids, smart grids, micro-grids, etc., there has always been a baggage of responsibility on the protection engineers to come up with a novel, operative, and optimized way to clean faults in the distribution on transmission lines, which focuses on maintaining a maximum tripping time for the point located at the farthest position from the actual location of the fault. Radial networks are susceptible to overcurrent fault conditions. So, for the protection against the faults, the overcurrent relays are used. For a power-protection engineer, it is imperative to maintain and optimize the coordination time interval (CTI) between relays in the course of overcurrent relay coordination. For the clearance of the fault, optimization algorithms are often fetched. In this paper, brute force algorithm and simulated annealing algorithm are implemented on a radial network to optimize the time dial setting (TDS) of relays. Thus, helping to maintain coordination among OC relays in the network.
