Modern electrical substations are managed by intelligent electronic devices communicating through Ethernet-based networks. Because of the highly critical roles of substations, which include safety and protection, electronic devices need to be configured automatically through highly reliable and low-latency networks. This gives substation networks some requirements not addressed by previous industrial network standards. To address these unique challenges, IEC 61850 provides a collection of protocols and a model for the automatic configuration of digital substations. This article briefly overviews this standard and the security efforts to protect substations from attacks.
Akal ha publicado en castellano el libro de Giuseppe Vacca, Vida y pensamiento de Antonio Gramsci, 1926-1937 (2020), el cual fue inicialmente publicado en italiano en el año 2012 gracias a la editorial Einaudi.
