ExpDTS — Hybrid dispatcher training simulator expert system for operator assistance and evaluation

Dispatcher Training Simulators are complex applications included usual in SCADA systems and using their models, data and graphic interface. This paper presents ExpDTS, a simple off-line dispatcher training simulator which has the main functions needed for training and was realized by the author, after a deep research in the training simulators´ domain. This simulator is a hybrid application, expert system and classical program, and has the following functions: system monitoring and control, events logging, short circuit simulation, operator assistance and evaluation. The system state changing in time is based on load variation, and can be determined also by an events scenario chosen by the operator. The paper presents the simulator´s functions, the structure and some ideas about mathematical models, graphical interface, and way of use.
