Etude d’un système photovoltaïque en vue du diagnostic

Abstract

t he remarkable expansion of global industry and constantly energy need require to explore a sustainable, efficient and green energy source. The solar PV energy is a worthy and interesting candidate especially for a country like Algeria, which has a large area of solar irradiance incidence. While the appearance constantly fluctuating energy source requires more of control and investigation. Indeed, such as all industrial systems, during operation, it is quite likely that a PV system get in failure, therefore reducing its performance and could interrupt power generation. To ensure a continuity of service and operation with good performance, it is interesting to perform a thorough study on the PV systems. This is done by means of distinguishing the types and characteristics of PV systems and studying the defects that may affect their operations. A fault diagnostic technique leads to a highly viable and reliable operation simultaneously. The opted fault diagnostic approach requires a solid modeling to well simulate the PV system output in point of view of power and the specific I-V curve shape similarity of the GPV.
