Otimização de um simulador didático de sistema supervisório (SCADA) para disjuntores de alta tensão

Abstract

This work addresses the optimization of an educational Supervisory Control and Data Acquisition (SCADA) system simulator aimed at the control and monitoring of bistable circuit breakers in electrical power systems. The research is based on the Chronos prototype, previously developed to perform supervision, control, and data acquisition, as well as the analysis of overcurrent relay operating curves. The proposed optimization covered three main aspects: the development of a printed circuit board (PCB), replacing the breadboard assembly; the redesign of the Human-Machine Interface (HMI), prioritizing usability and clarity of information; and the implementation of an operational logic based on automatic circuit breaker state detection and continuous data transmission through bluetooth communication. The obtained results demonstrated significant improvements in operational stability, measurement reliability, and user experience. The implementation of the PCB contributed to noise reduction and increased system robustness, while the redesigned interface provided more intuitive interaction. Continuous communication enabled more efficient real-time supervision, eliminating the need for manual requests. Thus, the optimized system preserves the low-cost and flexible characteristics of the original prototype, consolidating itself as an effective educational tool for teaching automation, control, and protection of electrical power systems.
