The collaboration between CEA and Ener-Pacte has brought these technologies to maturity. Enabling efficient operational use.
The ASPIRE software can import multiple information such as infrared images, RGB images in the visible range, electrical diagrams of power plants, voltage-current measurements. It also enables the user to manipulate and visualize data in an intuitive way.
Segmentation algorithms ensure the automation of diagnostics.
The detection of good or defective modules by segmentation algorithms and thermal analysis is ensured with an accuracy of 91.4% and 93.5%. The model then allows the classification of defects of faulty modules (hot spot, diodes, PID, disconnection, junction box). The algorithms are the subject of a patent application.
Finally, the estimation of power loss by coupling imaging and electrical information also gives good results: it is consistent and complies with the losses of known defects.
The IV-Diag software allows to analyze data from IV tracer and to extract the type of defects. The software has been validated on several data sets from the field.
Its current performances are very promising in terms of detection and identification rates.
Thanks to an automated and reliable fault detection, Ener-Pacte will be able to optimize its diagnostics and reduce its audit and operating costs.
