Etude et diagnostic des défauts fréquents aux systèmes photovoltaïques (PV) par emploi de la caractéristique courant-tension

Abstract

Photovoltaic systems like all electric and electronic systems can be broken down and degraded during the operation life. This will require a diagnosis whose principal goal is to provide a tool to make possible the energy production maximum level of these systems. In addition, this has led our intention to build a document covering the essential information to instigate the world of the photovoltaic systems, diagnosis while being based up-on the analysis of the current-voltage characteristic, and for the more faults discrimination purpose we used the Fuzzy Logic approach. This work has been achieved through a simulation process using the Bishop model with different Photovoltaic configurations. This model choice has been established to getting a better detection of defects than that of classic model.
