Evolución de los métodos de evaluación de la confiabilidad para redes eléctricas de distribución Evolution of reliability assessment methods for electrical distribution networks

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