Q1. What are the contributions in this paper?
9 This work proposes a fault detection algorithm based on the analysis of the theoretical curves which 10 describe the behaviour of an existing grid-connected photovoltaic ( GCPV ) plant. 13 Furthermore, a third order polynomial function is used to generate two detection limits ( high and low 14 limit ) for the VR and PR ratios obtained using LabVIEW simulation tool. Furthermore, 17 samples that lies out of the detection limits are processed by a fuzzy logic classification system which 18 consists of two inputs ( VR and PR ) and one output membership function.
