局部阴影下光伏阵列各拓扑结构输出特性研究
|
摘要
局部阴影条件下,不同拓扑结构的太阳能电池板具有不同的功率输出特性,直接影响到整个光伏阵列输出效率。文中在局部阴影条件下光伏阵列数学模型的基础上,设计并搭建SP、TCT和BL 3种拓扑结构4×4光伏阵列的仿真模型。在各局部阴影情形下,对3种拓扑结构的最大输出功率进行仿真并对仿真数据对比分析。研究表明,在不同阴影移动模式中,光伏阵列的最大输出功率与拓扑结构呈现一定的规律性,对光伏电池板拓扑结构设计有一定的借鉴意义。
Under the condition of partial shadow, solar panels of different topologies have different power output characteristics, which directly affect the output efficiency of the entire photovoltaic array. Based on the mathematical model of photovoltaic array under partial shadow conditions, the simulation models of 4*4 PV arrays of SP, TCT and BL were designed and built. In each case of partial shadows, the maximum output power of the three topologies was simulated and the simulation data was analyzed. The research showed that the maximum output power and topology of the PV array exhibited certain regularity in different shadow movement modes, which had certain reference significance for the design of photovoltaic panel topography.
