Implementação de um sistema de controle supervisório e aquisição de dados para usinas de geração distribuída voltada à energia solar fotovoltaica

Abstract

The SCADA system (Supervisory Control and Data Acquisition), also known as supervisory control and data acquisition, has as its main functionality to supervise and control an automation process, which can be a power generation or industrial system. As the market demand for renewable energy is on the rise, there is an intense demand for photovoltaic solar energy. From this, a SCADA system with a high degree of reliability for monitoring photovoltaic solar plants was improved. Therefore, the ScadaBR program was used, as it is an open-source software capable of meeting the needs of the work. A meteorological station with temperature and solar irradiation sensors was also developed to verify the functioning of the energy generation system. This work presents the versatility that the SCADA system provides, being able to be implemented in the most diverse projects, it no longer provides a tool capable of collecting meteorological data and the photovoltaic energy generation system. The work showed the applicability and advantages of this system, as well as calibration methods for DHT22, LDR and SCT-013-000 sensors, presenting real-time data in a man-machine interface.
