Virtual reality training system for the maintenance of underground lines in power distribution system

The application of Virtual Reality technologies in training process has been shown as an powerful tool. The 3D representation of real world and interactivity with it seems to be a more natural learning media than other traditional tools. This paper presents the application of virtual reality technology to training of underground lines operators in Distribution Power System. The system is composed of three main modules: virtual reality catalog, training mode and evaluation mode. The virtual reality system includes a learning management system to assess the operators' learning progress. The system incorporates forty different maintenance and operation maneuvers for high, medium and low voltage underground distribution networks. The system has been applied for training operators of all the divisions of a nationwide electric utility with excellent results.
