Intelligent Transmitter of Field (ITF) Based on Microcontroller for Data Acquisition in PV Solar Plants

Abstract

In this article the design of a prototype of an Intelligent Transmitter of Field (ITF) is presented. The objective of this ITF is to be used as a data acquisition in a PV solar plant implemented at the new Campus, the Diagonal-Besòs Campus, of the Technical University of Catalonia – BarcelonaTech (UPC). Aspects like power consumption of the electronic circuits, energy supply through the wires of communication of the transmitter, the coexistence in these wires of analogical signals of measurement and digital signals of communication, etc., are essential to get the foreseen objective. The article seeks, also, to contribute to obtain a practical and, at the same time, didactic solution for a problem that has been one of the main challenges in instrumentation field for data acquisition in renewable energy systems.
