Progress in Signals and Telecommunication Engineering Leandro Mattioli, Alexandre Cardoso, Edgard Lamounier, Gerson Lima, Alexandre Carvalho1 4 1 2015 A Virtual Reality System provides intuitive tridimensional user interface, with distinct interaction when compared to traditional 2D widgets layout, allowing the user to manipulate data similar to real world. Such systems give the users physical and cognitive immersion, by granting a mental model compatible with field operation. This paper presents some development aspects and results of the GT 411 Research and Development project, involving CEMIG GT and the Federal University of Uberlândia. A VR environment is applied, in novel ways, in the training, operation and control of power systems. Such tool enhances Operations Center interaction capabilities by making use of multisensorial devices, with easy and natural manipulation and a high immersion level. Besides operating generation and transmission actives, the environment presents great potential for the training of operators and other professionals of support and maintenance.
