A Web-based virtual environment for operator training [for powersystems]

摘要

The wide accessibility and low cost of virtual reality (VR) on thenWorld Wide Web with the advent of the Virtual Reality Modelling Languagen(VRML) and VRML interpreters makes it ideal for use in providingncost-effective training for operators in selected complex technicalnenvironments. This paper presents SEDA-VRML, a VR-based learn-by-doingnsystem developed for the training of maintenance workers in thentroubleshooting and inspection of power transformers at Hydro-Quebecnthat is accessible from a Web browser. SEDA-VRML is a prototypenapplication of a reuse-driven design incorporating VRML, Java and annexpert system within a user interface system (UIS) architecture. Thenpaper describes the functionality and design principles of SEDA-VRML,nwith key implementation results, to show how SEDA-VRML's design cannindeed answer to the limitations of VRML to act as a cost-effectivenalternative to traditional operator training systems for operatorntraining in VR, as well as a basis for the rapid development of futurenoperator training systems
