Desenvolvimento de um simulador didático de sistema supervisório (scada) para disjuntores de alta tensão

Abstract

This work presents the development of a Supervisory Control and Data Acquisition (SCADA) System designed to monitor and control a high-voltage bistable breaker. The main goal was to create an embedded system that integrates sensors, microcontrollers, and electronic components, allowing for quick interventions based on real-time data about the state of the breaker. Additionally, a function for collecting the operating curves of overcurrent relays was included. The implementation involved programming algorithms on the Arduino Mega, with the incorporation of a Bluetooth module for communication with external devices such as smartphones. The Human- Machine Interface (HMI), developed in MIT App Inventor, provides an intuitive experience for the end user. In addition to enabling control and supervision of the breaker, the system also performs additional functions, such as collecting the operating curve of a digital relay. The obtained results demonstrate the effectiveness of the developed embedded SCADA system, offering a flexible and financially accessible solution for controlling the bistable breaker in didactic experimental environments.
