dc.description.resumo	Recently a large number of small units of electric generation are being installed in the electric power distribution system in Brazil, due to the governmental investments on renewable energy. Modifications in the settings of the protection system may be caused by the high penetration of distributed generation (DG) in the electric system and parameterize the protection system for this new setting is necessary. However, this task is being made with much difficulty in many companies which use the conventional methods. In this paper, an adaptive protection scheme is proposed to determine instantaneous overcurrent relay setting. Frequency estimation was used to determine load and power supply changes in a real Brazilian system, and these modifications on the system were used to the adaptive protection block to determine the update on relays settings. The application of frequency estimation methods to adaptive overcurrent protection presented good results and improvements on the protection of the electric system	pt_BR
