Detection Of Faults In Photovoltaic Modulein The Frequency Domain
Authors : Tafinine Farid . Behloul Fatiha .
Abstract
A photovoltaic system can be subject to various faults and anomalies during its operation,leading to a drop in performance. Allowing fine diagnosis, detection and localisation of faults in a Photovoltaic (PV) installation reduces maintenance costs and above all increases productivity. In what follows, we focus specifically on the detection andlocalisation of faults on the AC side of the PV system. For this purpose, the choice was made to analyse the power generated by the PV in the frequency domain for the various operating modes under consideration. Based on the spectral analysis of the threephases of the generated currents, faultscharacteristic frequencies are highlighted in the power spectral density of the first principal component. The diagnosismethod gives a good basis for a non intrusive condition monitoring tool for PV system
