Redundancy in communication networks for the automation and protection of electrical power systems with IEC 61850

This article describes a detailed study and analysis of the redundancy protocols used for automation networks and power systems. According to requirements for communications network, protocol services and messaging services, presented in the IEC 61850 standard, the use of network protocols is required to ensure the maximum time allowed in communications failure. As a solution, the edition 2 of IEC 61850 standard, refers to use of two redundancy protocols according to the IEC 62439-3 PRP- HSR standard, which are part of the study object. Also, the design and implementation for the study case of a 230kV electrical substation of the Group Energía Bogotá was carried out, with a hybrid redundancy scheme HSR-PRP. Its behavior was analyzed and validated obtaining satisfactory results for the services required by the control and protection system of the Substation. © 2019 Centro de Informacion Tecnologica.
