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

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.
