摘　　要：在光伏电池数学模型基础上,对采用分布式MPPT的光伏系统输出特性进行分析。在实际光伏电池组件上加装分布式MPPT测量正常情况下和有遮挡情况下的输出特性及效率,得出分布式MPPT具有宽输入/输出电压范围,系统中的单块组件功率输出受限不影响系统中其他组件输出,最大化能量采集和输出,使得光伏电池的利用项目更加可行。On the basis of mathematical model, the output characteristics of photovoltaic module with distributed MPPT were analyzed. In the actual photovoltaic module with distributed MPPT, the output characteristics and efficiency were measured in normal and shadow background. The results show that the distributed MPPT has wide input/output voltage range; the limited output of single module power does not affect other module output; energy collection and output are maximized, making the utilization projects of photovoltaic battery more feasible.
