Sensoriamento remoto de potência para o sistema fotovoltaico conectado à rede do escritório verde da UTFPR

Abstract

The distributed generation model allied with the new technologies focused on a more efficient and less polluting energy sources, such as photovoltaic systems and eolic power plants have gained importance both in the national and international scenario. The evaluation performance of these systems connected to the grid have great value to the planning and expansion development of these technologies. The analysis of these systems is conditioned to the collecting and storage of his data. Since the Green Office at UTFPR, regional center of reference in sustainability, lacked a monitoring system for the consumption and production of the photovoltaic system connected to its grid, in this paper was proposed to implement a monitoring and storage system for the power data of this building. With the purpose to correct this deficiency was implemented a low cost system using a Raspberry PI with NodeRED software, and the already installed system of measurement. This system is able to give the main power parameters, such as active and reactive power, in addition to quality parameters like total harmonic distortion (THD) and power factor.
