常见光伏阵列拓扑结构分析

Topological Analysis of Common PV Arrays

太阳能光伏发电系统作为一个复杂系统,其中光伏阵列拓扑结构对整个系统的成本和效率有着重要的影响,它也关系着发电系统能否经济可靠地运行。对比分析了几种常见的光伏阵列拓扑结构,并对常见失配条件下阵列输出功率的仿真结果进行分析。分析研究表明阵列拓扑结构对光伏系统输出功率和成本有很大影响,这些研究为光伏阵列拓扑的设计提供了参考。

As a complex system,the topology structure of the PV array has a significant influence on the cost and efficiency of the whole system,and it is also related to the economic and reliable operation of the power system. This paper studies some common topology structures of PV arrays and analyzes the simulation results of the power output under the common mismatch conditions. The analysis shows that array topologies have a great influence on its output power and cost,and the research provides some useful references for the design of the photovoltaic array topology.
