Métodos de localización de fallas en sistemas eléctricos de distribución con presencia de generación distribuida

The location of faults in the electrical systems, especially in distribution, is a problem that affects not only the users, but also the companies providing the electric service; with more time invested in this period, the losses due to the unbilled energy and the inconvenience in the users are increased, decreasing the quality of the service. The causes for which this time is increased are different, among them the confusion that could exist in the location systems that act under the presence of sources of distributed generation in the distribution networks. In this sense, the present investigation shows a revision of the methods used for the location of faults in electrical distribution systems that have presence of sources of distributed generation. The main characteristics of the methods are studied and their most recent applications to deal with this problem.
