Abstract
This paper deals with the fault detection of solar energy production source system (SEPSS) based on the least squares method. This choice resides on its implementation simplicity and also rarely use in the diagnosis of a SPESS. In first, an analytical model of the photovoltaic (PV) module based on the Bishop model is exposed. Also, the least squares method is detailed. These models have been implemented on the Maltab software to study the healthy and faulty PV cases. As default type, the partial shaded PV is considered. Then, some simulation results are presented by analyzing several characteristic quantities of the PV such as the voltage, electrical current and output power. Some other interesting results will be presented in the full paper. Moreover, the second part of the work which deals with the classification of fault level by fuzzy logic approach will be analyzed in the full version paper. The overall results of this approach are very encouraging and could lead to a low cost diagnostic approach.Keywords
