태양광발전에서 PV모듈 불량 검출방법 = The detection method of faults in photovoltaic module for photovoltaic generator

다국어 초록 (Multilingual Abstract)

This paper presents the detection method of faults in photovoltaic module for photovoltaic generator. Degradation of insulating materials and deterioration of electrical connections may be the most serious problems creating series or parallel arcing faults in PV system. And in case of partial or total shading, reverse currents waste power and can also lead to overheating of shaded cells. The proposed method is measured individual PV module voltage/current, and compares each PV module voltage/current, and detected fault and shaded cells. The simulation and experimentation take sunlight irradiance and cell temperature with mismatched condition that work under uniform and mismatched PVs to prove the validity of the proposed detection method.
