光伏组件雷电冲击损伤特性实验研究
Experimental Study on Lightning Impact Damage Characteristics of Photovoltaic Modules
摘要
Abstract
By using high voltage and high current im-pact simulation experiments,the lightning damage characteristics of photovoltaic modules were analyzed,and the key damage characteristics such as the dam-age morphology,lightning path,damage threshold and the change of electrical characteristics were ob-tained.The results showed that in the case of natural lightning,most of the photovoltaic frame or bracket was connected with lightning,and the lightning cur-rent of 20 kA can cause the border ablation.Light-ning will affect the function and life of the compo-nent.With the increase of lightning impulse voltage,the maximum output power gradually decreased.When the impulse voltage was 300 kV,the maximum output power change rate reached 10.02％.Based on the simulation results of lightning damage experi-ment,it can provide data support and reference for lightning protection of photovoltaic system.关键词
