The importance of High-Voltage Direct Current (HVDC) transmission systems is growing due to the rising trends of digitalization, decarbonization, and distributed generation in the energy industry. These systems provide an efficient means of transmitting large amounts of power over long distances, while also connecting renewable energy sources to the power grid and balancing three-phase grids. Virtual Reality (VR) and Augmented Reality (AR) technologies present a range of opportunities to address challenges in the energy industry. In this study, we propose a methodology to implement a VR and AR system for the energy electric company Eletronorte that facilitates visualization, navigation, and interaction with the arrangements and components of the HVDC system substations. The project involves developing modeling techniques to improve the representation of the components, updating preventive maintenance procedures, and creating a system monitoring environment using VR and AR, enabling engineering teams to interact with field teams and integrate real and virtual systems. VR simulations will provide a safe and controlled environment for training and testing, while AR simulations can be used to provide real-time guidance to technicians in the field. This approach can improve the efficiency and dependability of stepby-step activities, while also reducing the time and costs associated with system maintenance. [ABSTRACT FROM AUTHOR]

Virtual Reality-based systems can provide intuitive and distinct three-dimensional user interfaces compared to traditional two-dimensional layouts. Such systems give the users physical and cognitive immersion, which results in a mental model that is quite consistent with field operation. In this work, we present the development aspects and a case study of a solution based on Virtual Reality to provide a more natural and intuitive environment for controlling electrical operation centers. The solution intends to minimize the issues caused by the operation of electric power substations due to the lack of spatial and functional information on the traditional operation interfaces. The research is being carried out with the collaboration between the energy electric company of Minas Gerais-Brazil (CEMIG) and the Federal University of Uberlândia. Besides operating generation and transmission actives, the environment presents great potential for the training of operators and other professionals of support and maintenance. [ABSTRACT FROM AUTHOR]
