Esta dissertaĆ§Ć£o tem por objetivo estudar os princĆpios, mĆ©todos, tecnologias, e equipamento atuais para sistemas de monitorizaĆ§Ć£o de centrais solares fotovoltaicas Ć distĆ¢ncia por IoT.
Efetuar a anĆ”lise de soluƧƵes de sistemas de monitorizaĆ§Ć£o de centrais solares fotovoltaicos, resultados de estudos e desenvolvimentos da comunidade cientĆfica, e da norma ISO 61724:2017.
SĆ£o analisados diversos tipos de sensores, sistemas de mediĆ§Ć£o e princĆpios de funcionamento, assim como outros componentes do sistema de monitorizaĆ§Ć£o, com avaliaĆ§Ć£o da incerteza de mediĆ§Ć£o, quando aplicĆ”vel, associados Ć monitorizaĆ§Ć£o de centrais solares fotovoltaicas por IoT.
ImplementaĆ§Ć£o prĆ”tica de um sistema de monitorizaĆ§Ć£o por IoT a um pequeno grupo de painĆ©is fotovoltaicos existente no Instituto PolitĆ©cnico de SetĆŗbal, recorrendo a opƧƵes, equipamentos e soluƧƵes, de custo reduzido, mas cujos princĆpios de funcionamento podem ser transportados e representativos de implementaĆ§Ć£o em soluƧƵes mais complexas, de maior dimensĆ£o, superior exatidĆ£o e precisĆ£o na monitorizaĆ§Ć£o.
Recurso a sensores com saĆda analĆ³gica, utilizaĆ§Ć£o de placas microcontroladores com ADC integrado, da marca Arduino, e comunicaĆ§Ć£o sem fios atravĆ©s da comunicaĆ§Ć£o do tipo LoRa. Arquivo, anĆ”lise, e visualizaĆ§Ć£o de dados de monitorizaĆ§Ć£o atravĆ©s de uma base de dados localizada na internet para ser acessĆvel em qualquer ponto com ligaĆ§Ć£o Ć internet.
Com transmissĆ£o sem fios atravĆ©s da banda ISM-Industrial Scientific and Medical, os dados das mediƧƵes dos sensores relevantes do conjunto de painĆ©is fotovoltaicos, foram transmitidos para uma antena recetora a uma distĆ¢ncia, sensivelmente, de 700 m sem obstĆ”culos na linha de vista, e a 120 m dentro do edifĆcio do campus do IPS. No sistema de receĆ§Ć£o, apĆ³s verificaĆ§Ć£o da integridade dos dados, estes eram enviados para uma base de dados localizada na internet, onde foi criado um painel de controlo, que permitiu a monitorizaĆ§Ć£o das mediƧƵes em qualquer ponto com ligaĆ§Ć£o Ć internet.
AnƔlise e conclusƵes dos resultados obtidos e propostas de melhoria do sistema implementado.
This dissertation aims to study the principles, methods, technologies, and current equipment for IoT monitoring systems of solar photovoltaic power plants. Analysis of solar photovoltaic power plant monitoring systems, based on scientific developments carried out by community studies, and study of ISO 61724:2017- Photovoltaic system performance monitoring. Analysis of different types of sensors, measurement systems and operating principles, as well as other components of monitoring system, with evaluation of the measurement uncertainty, when applicable, associated to IoT monitoring of solar photovoltaic plants. Practical implementation of an IoT monitoring system to a small group of photovoltaic panels located in the Polytechnic Institute of SetĆŗbal, using options, equipmentās, and low-cost solutions, but whose operating principles can be transported and representative for implementation to monitor more complex solutions, bigger dimension, with greater accuracy and precision. Use of sensors with analogue output connected to microcontroller boards with integrated ADC, Arduino brand, and wireless communication through LoRa communication. Archive, analysis, and visualization of monitoring data through a database located on the internet to be accessible from any point with internet connection. With wireless transmission over the ISM-Industrial Scientific and Medical band, measurement data from the relevant sensors of the photovoltaic panels were transmitted to a receiver antenna at a distance of approximately 700m in free space, and 120m inside of building of the IPS campus. In the receiving antenna, after checking data integrity, it was sent to a database located on the internet, where a control panel was created, which allowed monitoring of the measurements from any point with internet connection. Analysis and conclusions of the results obtained and proposals for improving the implemented system.
