Development of a Low-Cost Fault Detector for Photovoltaic Module Array

摘要: This study proposes a binary search-based fault detection system for photovoltaic (PV) modules to ameliorate the deficiencies in existing detectors PV module arrays. The proposed applies single-chip microcontroller execute search algorithm. Moreover, overcome multi-node voltage and reduce number of integrated circuit components, an analog switch is used perform channel switching; results are displayed on software platform developed using Visual C#. does not require learning diagnosis arrays has advantages including high accuracy low construction costs. Finally, verify feasibility system, this simulated abnormal situations actual applied algorithm maximum power point tracking detect malfunctions
