基于可变拓扑结构的太阳能光伏发电系统设计

Development and Design of Solar Photovoltaic Power Generation System Based on Variable Topology

文中针对原有固定的拓扑结构的太阳能光伏系统对不同强度的太阳光不能进行调整,使得发电量效率低下,资源未得到较好的利用,提出了基于可变拓扑结构的太阳能光伏发电系统。该系统通过光强传感器检测的光强信号控制继电器的触点,改变光伏板固有的拓扑系数,实现了可变的拓扑结构,使得系统输出的电压电流稳定,且提高了光伏发电系统的效率。

In this paper,solar photovoltaic systems with fixed topologies cannot adjust the sunlight of different intensities,which results in inefficient power generation and the resources are not well utilized. A solar photovoltaic power generation system based on a variable topology is proposed. The system controls the contact of the relay through the light intensity signal detected by the light intensity sensor,changes the inherent topological coefficient of the photovoltaic panel,realizes a variable topology,makes the system output voltage and current stable,and improves the efficiency of the photovoltaic power generation system.
