NEW PARADIGMS IN SUBSTATIONS: ADVANCES, PROTECTION, AUTOMATION AND TRENDS IN ELECTRICAL POWER SYSTEMS

Abstract

This research substantiates the presentation and analysis of the new integrated systems of protection, supervision, control and automation of electric power systems adopted in Brazil and in other countries, and has as general objective the evidence of their main advantages in relation to non-integrated systems as well as the indication of trends and mega-trends in the area of application and related areas; and, as specific objectives, the record of the evolution of these systems, the exposition on substations and their general aspects of the protection of electric systems, in addition to the record of the description of their main constituent parts and the new control and monitoring functions available by digital equipment. To achieve these objectives, we adopted a methodology based on a literature review of documentary, historical, and technical nature, including research in indexed web databases, books, articles, dissertations, and theses on these and related topics. Finally, we note that the descriptions of the advantages and disadvantages of implementing protection and automation systems also analyze the steps involved in commissioning a substation, explaining the concepts, methods, and rationale for using integrated automation systems in substation protection, as well as some examples of digital protection in use.
