Distribution networks are evolving towards the vision of smart grids, by challenging the outlines of traditional protection, since the radial concept of unique feeding no longer adopts. One of the preoccupations related with the effects of the insertion of the generation distributed GD is the problems of selectivity and coordination of the devices protection must particularly to the changes in magnitudes and directions of the currents of short circuit. Thoses problems affect directly the security of equipment, personal and continuity of the service. A proper coordination of electrical protections is fundamental in electric power systems, with the aim of avoiding unexpected disconnections. These disconnections can produce problems in the operation of the power system and in its different components. This thesis presents an adaptive overcurrent protection system which automatic amends the protection settings of the overcurrent protection system. in answer to the change of topology of the electric system of distribution (connection/disconnection of GD, cast a net active and isolated operation). The outline has been elaborated by using the devices of commercially available protection, employs IEC61850 based communications. The computational tool for the attainment of this objective is the Digsilent Power Factory program. A systematic comparison of the performance of the proposed adaptive scheme is presented. This comparison quantifies the decrease in the false operations and the reduction of mean operating time that the adaptive system offers.
