Photovoltaic fault diagnosis algorithm using fuzzy logic controller based on calculating distortion ratio of values

Introduction. The efficiency of solar energy systems in producing electricity a clean way. Reliance on it industrial and domestic has led to the emergence malfunctions its facilities. During operating period, these deteriorate, this requires development diagnostic system aimed at maintaining production maximum rate by detecting faults as soon possible addressing them. Goal. This work proposes an algorithm detect photovoltaic system, which based fuzzy logic. Novelty. Calculate distortion ratio voltage current values resulting from each element processing logic controller, leads determining nature fault. Results. As show results using control calculating 12 array, converter DC-DC battery.
