Abstract
This project presents the results obtained from a new strategy based on Virtual Reality techniques, which intends to minimize the operational issues caused in electric power substations due to the lack of spatial and functional information on the traditional operation interfaces. For this purpose, a three-dimensional interactive virtual reality environment was built in a realistic and accurate way regarding an energy supplier substation in Minas Gerais - Brazil and subsequently implanted it in its operation center for tasks related to its functioning. Lastly, tests were applied to operators to obtain results aiming at the contextualized problems.
Highlights
In the electrical sector, the energy suppliers have continuously employed efforts which intend to improve the quality and continuity of their power supply to their customers (Bernardon et al 2016).supply interruptions are inevitable for various reasons, : execution works in system expansion, preventive and/ or corrective maintenance on the grid’s components, or even human errors in the operation of the national interconnected system (Porto et al 2017).In the context of human errors, statistical analysis shows that these errors in a system correspond up to 90% of the total failures (PengCheng 2012).Historically, in Brazil, major blackouts that occurred in the national interconnected system are related to human error in its operation
It allows its user to manipulate information that is similar to the real space while being favored by the immersion feeling, which is the major characteristic in these environments, for it being the responsible of producing the feeling of presence in the virtual world (Landberg 2000). This way, facing the scenario of the difficulties dealt in the electric system’s operation process and the potential of the Virtual Reality field, this research has the objective to develop and evaluate a system based on Virtual Reality techniques that allows transmitting spatial and functional information in the process of electric power substations operation
It is crucial that the operator can assimilate the operation interface in a way that there is no difference between it and the real field, and for this purpose, it is important to develop strategies that transmit spatial and functional information
Summary
The energy suppliers have continuously employed efforts which intend to improve the quality and continuity of their power supply to their customers (Bernardon et al 2016). One of the main error-causing conditions related to the operation of Engineering Systems is based on the absence of an interface to transmit spatial and functional information to the operator in a way that he/she can readily assimilate Contrasting this problematic, the application of Virtual Reality techniques aims to develop a more intuitive interface that maximizes the interactivity, usability and naturality aspects during the action process (Kirner & Kirner 2011). It allows its user to manipulate information that is similar to the real space while being favored by the immersion feeling, which is the major characteristic in these environments, for it being the responsible of producing the feeling of presence in the virtual world (Landberg 2000) This way, facing the scenario of the difficulties dealt in the electric system’s operation process and the potential of the Virtual Reality field, this research has the objective to develop and evaluate a system based on Virtual Reality techniques that allows transmitting spatial and functional information in the process of electric power substations operation. Immersion: immersion stands for the objective level of sensory fidelity provided by a VR system, whereas presence is the subjective psychological response of a user experiencing a VR system (Slater 2003)
