The stator contains a winding made by connecting in series (Al) the conductors shown in their crosssection in figure. A simplified idea on how these connections are made can be inferred from the second image that shows winding. This winding, called field winding, during the machine operation is connected to a DC source and therefore is traversed by a DC current.

Aims: The main objective of this research is to develop a hybrid optimization algorithm which consists of modified firefly algorithm and genetic algorithm to find better solutions.
Methodology: First, this study modified the original firefly to obtain a global solution by updating the firefly's brightness and to avoid the distance between individual fireflies from being too far. Additionally, the randomized movements were controlled to produce a high convergence rate. Second, the optimization problem is solved using standard genetic algorithm. Finally, the solution obtained from the modified firefly algorithm is used as the initial population for the standard genetic algorithm. The modified firefly algorithm, genetic algorithm and hybrid firefly-genetic algorithm have been tested on IEEE 3-bus, 8-bus, 9-bus and 15-bus networks.
Main Results: The results indicate the effectiveness and superiority of the proposed algorithms in minimizing the overall operating time of primary relays compared to other algorithms mentioned in the literature for directional overcurrent relays coordination.
Conclusion: Compared to modified firefly algorithm and standard genetic algorithm, the proposed hybrid algorithm has minimized coordination interval time between primary and backup relay pairs.
In understanding power protection, it is necessary to understand what is actually being protected. Providing superior protection is essential in mitigating the effects of disruptions on system stability. As such, it is essential for power engineers to understand the concepts and practices of underlying power protection.
