Desenvolvimento e avaliação de um protótipo para monitoramento e aquisição de dados climáticos para geradores fotovoltaicos

Abstract

This work aims at the development and evaluation of a monitoring and data acquisition prototype to collect climate data for photovoltaic arrays (PV). It takes into account that, due to an increasing energy demand, renewable sources are becoming a essential componente of the electrical world system. In order to improve the PV e_ciency, continuously monitoring of the wheather conditions where the system is installed is required. By using wind, temperature, current and voltage sensors, signal conditioning interfaces are developed. To accomplish the tests of the monitoring and data acquisition system, it is used a Siemens ProCharger 4JF PV, installed in Santa Maria, RS. The temperature and the wind speed data are collected by the system. The system Graphical User Interface (GUI) is based on LabView and the data acquisition is performed by a National Instruments USB NI-6251 board.
