System Operator Training using Simulators in Steady-State and Transient Regimes

Brazilian power system, based on the integration of a steady-state Operator Training Simulator

(OTS) with a dynamic simulation tool. This approach aims to make training sessions more interactive, realistic, and consistent with real-time operating conditions. The integration was enabled by an internally developed technological solution designed to connect both systems, significantly expanding the scope and realism of the simulations. The combined use of these tools provides a high-fidelity and immersive environment in which operators can apply operational procedures, make decisions, and observe their impacts in real time. This methodology has proven effective for both individual technical development and the continuous review and improvement of operational procedures, including the identification of inconsistencies or ambiguities. By incorporating dynamic simulation, the training environment allows the analysis of transient system behavior, such as electromechanical oscillations, frequency variations, and voltage deviations. These phenomena, which are critical to operational security, were not previously addressed in training environments based solely on steady-state simulations. The methodology requires careful preparation by the technical team, including scenario configuration, testing, and script definition, and follows a training dynamic analogous to a flight simulator, in which the system operator assumes the role of the pilot.
