Development of an integrated data-acquisition system for photovoltaic blocks mutualization monitoring using LABVIEW

The photovoltaic blocks mutualization (PVBM) is a system for recovering and using the excess of photovoltaic power produced from homes or consumers. This system is based on the Automatic control of interconnections of different photovoltaic blocks with different homes using a switching matrix. In this paper, the development of a computer-based system for PVBM system monitoring is described. The proposed system is used to oversight the switching matrix and control the allocation of each photovoltaic block. The purpose of this work is to implement into a FPGA Xilinx circuit, an algorithm for PVBM system integrated with UART (Universal Asynchronous Receiver Transmitter) serial communication protocol for monitoring the system. The LABVIEW program is used to further process and display collected data in the PC screen. The proposed architecture permits the rapid system development and has the advantage of flexibility in the case of changes, while it can be easily extended for controlling the PVBM system operation for any number of homes and PV blocks.
