摘要:
分布式先伏发电系统受安装方向和角度的影响,时刻处在不同的光照条件,采用常规的集中式、串式电气结构的发电系统容易产生热斑问题,且部分处在低光照条件的电池影响整个系统的性能,使最大功率点跟踪效率大大降低.在分析实际屋顶光照情况下,提出了一种并联式多支路分布式先伏发电系统,针对并联式多支路结构的电气特点,分析选取一种有源钳位变换器,在MATLAB环境下构建实验模型并仿真分析.仿真结果表明,该系统可有效提高系统抗阴影性能.
Abstract:
The distributed photovoltaic power generation system is affected by the installation direction and angle, and is in different light conditions at all times. The power generation system using conventional centralized and string electrical structures is prone to hot spot problems, and some batteries in low light conditions Affect the performance of the whole system, so that the maximum power point tracking efficiency is greatly reduced. In the analysis of the actual roof lighting conditions, a parallel multi-branch distributed photovoltaic power generation system is proposed. Aiming at the electrical characteristics of the parallel multi-branch structure, An active clamp converter is selected for analysis, and an experimental model is built in the MATLAB environment for simulation analysis. The simulation results show that the system can effectively improve the anti-shading performance of the system.
