Abordagem ontológica para modelagem do treinamento de operadores de sistemas elétricos.

Abstract

The industrial training of system operators in simulated environments favours the assimilation of technical procedures by reproducing similar to real situations experienced in the workplace. The experience and learning acquired in simulators is directly related to the quality and realism of the proposed training scenarios. However, the process of building training scenarios is a complex one, involving a large volume and variety of information. It also demands from the development team a multidisciplinary knowledge of the virtual environment design, education, specific field, etc.). In this research it is proposed a systematic approach for building training scenarios in simulation nvironments, for electric system operators. This approach was based, amidst other sources, on: the instantiation of domain ontologies; IEC 61970-301 and the ISO 10015 standards; in the context of training in electrical systems; training observations conducted at the Brazilian electricity company- CHESF and related documents kindly made available by this company. The components of a training scenario were described on the basis of the terms; relationships and constraints defined, thus enabling their reuse in a variety of other scenarios, through their configuration and combination, in accordance with the information stored in a knowledge base. The objectives of this study were: to propose a scenario authoring process to facilitate the building of scenarios supported by the formalization of knowledge in domain ontologies; to provide a reusable data structure capable of assisting tutors in the virtual environment authoring process; to facilitate the understanding of training requirements; to promote reusability and scalability of the objects represented in scenarios such as: animation components and simulation models. Both the ontologies and the training scenarios development process were validated through the authoring of real scenarios for training in 2D simulator in CHESF- Simulop and, authoring scenarios for the 3D-SimuLIHM Simulator, developed in LIHM UFCG.
