| Abstract | ||||
| This study discusses a workable fault-detection scheme for solar photovoltaic (PV) systems that was created based on power evaluation and observation against short circuit (line-to-line) faults. The goal is to maximize the power output from photovoltaic systems and improve their performance in the face of meteorological changes that might cause system failures such as wire disconnections and shorting between two potentials in the PV array. In order to identify the effectiveness factor and threshold indicator associated with a short circuit fault in a photovoltaic array, an explicit fault detection technique is developed. The validation of the suggested design scheme is supported by the simulation results on PV array. For a high number of PV modules, the processing effort is decreased, and the problematic area of the array is identified in a reasonable length of time. An explicit fault detection method can be employed to assess the effectiveness factor and threshold indication of each identified individual defective PV array element in order to guarantee MPPT of the utilized PV system. | ||||
