Virtual reality applied to a full simulator of electrical sub-stations

This paper presents an application designed to train electrical sub-station operators by means of a virtual reality environment.The application allows full viewing of any of the sub-stations in the power supply network. With the appropriate hardware (HMD, 3D mouse and tracking systems) it is possible to navigate into the virtual world and interact with the elements.Each of the sub-station components has been reproduced in the simulation model, including the behavior laws associated with it, so the complete functionality of the sub-station can be simulated.This module is built into a larger and more complex computer system composed of the actual sub-station control system, the Geographical Information System which defines the topology of the network, and the functional system which simulates the electrical behavior of the sub-station.The application automatically updates in the virtual environment any changes to the sub-station's design and allows access, from this environment, to information on every component.The virtual reality application has been implemented in a hardware configuration and has the same interface as that used in the control system of the real sub-station. In this way, the system developed can be integrated into a replica of the complete power supply network control system emulating a real sub-station, it being able to fully interact with the global system, and allow totally real situations to be simulated.
