Fault detection of photovoltaic arrays based on support vector data description

A photovoltaic (PV) power plant consists of a large number of photovoltaic arrays (PVAs). PVA fault detection is essential to reliable PV plant operation. This paper presents an accurate and cost-efficient PVA fault detection method. The proposed method uses Support Vector Data Description (SVDD) technique. Therefore, ground truth labeling is not required. In addition, it performs fault detection solely based on the data collected by existing...
