Plataforma aberta para ensino de proteção, automação e controle de sistemas elétricos de potência com IEDs físicos e virtuais padrão IEC 61850

Abstract

The creation of the IEC 61850 standard represented a milestone for communication in substation automation systems by defining standards to achieve interoperability in an environment permeated by proprietary protocols. Its conception and development aimed at conceptual stability, so that its latest version covers the entire range of innovations and demands that the power electrical system has gone through. Another technology that has been conquering space in the SAS is virtualization, due to the potential benefits in aspects such as reduced equipment costs and hardware dependency, as well as the optimization of operational activities. Within this context, this paper aims to present the development of a laboratory infrastructure for teaching protection, automation and control of electrical systems, composed of IEC 61850 standard IEDs, both physical and virtual, in order to contribute to the students learning and to qualify them in the most recent concepts and applications researched in this area. The platform also has the integration of OPC and SCADA software, and a six-phase tester, expanding the range of concepts that can be studied from it. In this sense, test scenarios were developed where the good dynamics between the virtual IEDs and the physical IEDs were verified, as well as the success of the virtual IEDs in performing logical selectivity with and without breaker failure. The tests also contemplated the application of OPC and SCADA, where it was possible to monitor the behavior of the breakers upon the occurrence of a failure.
