Plataforma para Ensino de Proteção, Automação e Controle com IEDs Físicos e Virtuais Padrão IEC 61850

Abstract

The advent of the IEC 61850 standard and its extensions has caused a tremendous impact on the substation automation protection and control (PAC) systems. New breakthroughs are taking place supported by the IEC 61850 that consider the virtualization of the Intelligent Electronic Devices (IEDs). In view of these technological advances, a modern PAC laboratory is essential for education and training of professionals and students of engineering and technology. This paper presents a PAC platform, implemented in the Electrical Engineering Department of the Federal University of Ceara, Brazil, to promote the understanding, technical knowledge, and tools in power system digital protection. The PAC platform aims to offer a hands-on and interactive training environment to facilitate the learning and foster analytical skills, critical thinking, and self-confidence on power system protection. The learning platform includes physical and virtual IEDs, notebooks and a relay test set connected to a Local Area Network (LAN). The design of a Virtual IED (VIED) is presented, and validation tests of the instantaneous overcurrent function are performed. Test results have shown horizontal GOOSE communication between physical IED and VIED. Thus, VIEDs were used instead of physical IEDs to build a PAC learning platform. The VIEDs provide a new effective means for training qualified personnel in the state-of-the-art in power system protection and for application on smart substation.
