摘要
设计了小型户用储能式光伏系统整体方案,重点介绍了整体电路设计情况,研究了控制系统中的最大功率点跟踪(Maximum Power Point Tracking,MPPT)控制原理。逆变器是系统的核心,重点研究了逆变器的离网工作模式、并网工作模式以及双模式之间的切换,介绍了逆变器中的主要硬件及技术参数。利用MATLAB软件对设计的控制系统进行模拟仿真分析,发现系统达到了预期效果,可以实现小型户用储能式光伏发电过程的有效控制。
The overall scheme of the small-scale household energy storage PV system is designed,focusing on the overall circuit design,and the Maximum Power Point Tracking(MPPT)control principle in the control system is studied.The inverter is the core of the system,focusing on the off-grid working mode,grid-connected working mode and the switching between dual modes of the inverter,and introducing the main hardware and technical parameters in the inverter.The designed control system is simulated and analyzed using MATLAB software,and it is found that the system achieves the expected results and can realize the effective control of small household storage PV power generation process.
