Intégration de nouvelles technologies en vue de la surveillance d'un système photovoltaïque

Abstract

Monitoring of power generation systems is indispensable and it has become one of the requirements in PV generation systems. The work of this thesis is a part of the context of integrating new technologies. It presents the design and the implementation of a wireless monitoring system for PV installations. The design of this system is based on LoRa long range wireless technology and ultra-low power consumption STM32L031C6 microcontrollers. The proposed system is composed of a set of autonomous wireless sensors connected with one or more monitoring systems. LoRa is a physical implementation, so higher network layer communication protocols are also presented. Network management is performed by the mobile monitoring device and data acquisition is performed on a computer equipped with a LoRa module. The results presented after running the system are the fruit of over than 30,750 data samples. This work offers easy system flexibility and scalability and it opens a range for other applications at PV plant level.
