Diseño de la coordinación del sistema de protecciones eléctricas en los alimentadores interconectados urbanos de la EERSA

Abstract

The work presented then responds to the need to obtain the most appropriate criteria for proper coordination of protections, from protection medium voltage distribution transformers until the relays that command switches that protect feeders in substations; making a preliminary analysis of the actual situation of urban interconnected feeders. Using software CYMDIST and taking into account field visits to verify the elements of the network, files provided by the Department of Distribution EERSA, protections and elements involved in certain urban feeders Riobamba are analyzed, and based on the results obtained are applicable to model and verify the distribution system under study as adjusted to reality, for further modification of feeders for different scenarios, resulting throwing an adequate system of protection, which is recommended take into account for future studies and an example to other feeders in the EERSA.
