Evolución de los métodos de evaluación de la confiabilidad para redes eléctricas de distribución

This paper intends to offer a brief panoramic about the evolution of the reliability assessment methods andthe specificities of the same ones during the characterization of the electrical distribution networks and toshow how the utilization of either method not depends only of availability of data and the existence or not ofregulations for the continuity of electrical service, rather besides depends of the approach to reliabilitystudies in point: selection of variants during the design, reliability improving options during the exploitations or maintenance management.
