摘要：

In this paper, a circuit-based simulation model of a photovoltaic (PV) panel by PSIM software package is developed, firstly. Then, a 3 kW PV arrays established by using the proposed PSIM model with series and parallel connection is not only employed to carry out the fault analysis, but also to represent its I-V and P-V characteristics at variable surface temperatures and isolations under normal operation. Finally, a novel extension diagnosis method based on the extended correlation function and the matter-element model was proposed to identify the faulting types of a 3 kW PV system. The simulated results indicate that the proposed fault diagnosis method can detect the malfunction types correctly and promptly. © 2007 Elsevier B.V. All rights reserved.
