基于I-V曲线变形特征与计算机视觉的光伏组件故障诊断

Early diagnosis of photovoltaic module faults is crucial to reducing maintenance costs. The I–V curve can be intuitively used for diagnosis, but traditionally, only certain feature points on the curve are extracted, neglecting the entire curve’s deformation characteristics. This article analyzes the I–V curves deformation characteristics based on three-diode model, and presents a novel diagnosis m...
