Multi-user Expert System for Operation and Maintenance in Energized Lines

Abstract

The article presents the development of a multi-user application in virtual reality for the training and theoretical-practical training of electrical maintenance personnel in the operation of energized lines. The environment has a safety explanatory room in which users will know each of the rules and protocols applied to perform maintenance maneuvers and operation of energized lines, a realistic work area of the electrical power system that starts from hydroelectric generation and passes through transmission lines, subtransmission to reach substations that raise or reduce the voltage for subsequent distribution. The environment has been created using photogrammetry techniques, WorldComposer, CAD design tools, Unity 3D, DigSilent Power Factory and Matlab to provide realism of electrical system behavior, emulating failures and critical conditions caused by external and internal emergency events. Experimental tests show the efficiency of the system generated by human-machine interaction in which operators interact between themselves and the ambience, facilitate immersion in an environment that offers to contribute to the development of their risk-free collaborative skills and abilities.

A structured review on game‐based learning applied to electrical power and energy engineering

“…An analysis of variance was carried out after 1 day of training, obtaining an improvement of 21% in the performed evaluations. Finally, Moreno et al [80] propose a VR environment based on photogrammetry techniques, 3D models, and commercial power system simulators. According to the activities in charge, the environment has been developed as an immersive multi‐user expert system for maneuvers on energized lines, for example, chief of maintenance, overseer, group chief, and operator.…”

Virtual Reality as a Training and Risk Management Tool in the Supply Chain: A Systematic Review

“…Como resultado de la indagación, se identificó que la principal herramienta de software utilizada para la creación de entornos virtuales es Unity, con un total de 8 menciones. Unity es ampliamente reconocida y utilizada en la industria debido que es una interfaz fácil de usar [20].…”

“…Además de Unity, se encontró que el software CAD (Computer-Aided Design) también fue mencionado en 3 ocasiones como una herramienta utilizada en el desarrollo de entornos virtuales, este es utilizado especialmente porque facilita la creación, importación y ensamblaje de estructuras [20,23]. Asimismo, se registró una mención para las herramientas WorldComposer, OpenGL y Unreal Engine.…”

Designing Virtual Reality Environments through an Authoring System Based on CAD Floor Plans: A Methodology and Case Study Applied to Electric Power Substations for Supervision

“…They are tools focused on games where users have deep knowledge and experience. For instance, Moreno et al [25] presents a training system created with Unity with the support of external software and plugins, such as WorldComposer, Adobe Fuse, SolidWorks and 3Ds Max. As a consequence, these tools can be impracticable for inexperienced users.…”
