Implementação de sistema remoto de gerenciamento e monitoramento de parâmetros para miniusina solar fotovoltaica

Abstract

The present work has as objective the implementation of a data management and monitoring system for the photovoltaic solar mini-plant located at the Federal University of Alfenas, Poços de Caldas campus and to compare the developed system with a commercial data acquisition system. The developed system presents collected parameters and also performance indicators obtained by numerical modeling. For this, measurement equipment was used and a data logger, a web server, a REST API and a responsive web application were developed. The data logger was developed using the Raspberry Pi 3 Model B single-board computer and the TimescaleDB time series database. The data collected by the data logger are synchronized and saved in the web server database through the REST API. The communication between the application and server is also done through the REST API, which returns the information requested by the application. The web application was implemented using web technologies and development libraries like React, Bootstrap and ApexCharts. The application was divided into pages for better visualization of data such as dashboard, production, system performance, measured parameters and weather. All pages present the data using graphs and tables, in addition to allowing the user to download the data in XLS or CSV format. In addition to the advantage of being encoded in low-cost languages and technologies, in contrast to a commercial data acquisition system, the developed system in the present work reached a percentage variation of 0.5361% in the field of monitoring the total AC power production of the monitored photovoltaic mini-plant, constituting the developed system as a valid mechanism for monitoring photovoltaic systems.
