光伏发电系统功率最大化方法研究与实现

摘要

为实现光伏发电系统效率的最大化,可采用最大功率跟踪( Maximum Power Point Track-ing,简称MPPT)的控制方法。该文设计了以C8051F020单片机为控制核心,采用MPPT方法的控制器,提高了光伏发电系统的效率,实现了对工作状态和蓄电池能量的控制和管理,有效地保护了蓄电池,且系统运行稳定。%In order to maximize the power of photovoltaic system, the maximum power point tracking (MPPT)is used. This paper designs a MPPT controller which with C8051F020 SCM as control core. The application shows that the controller maximizes the power of electricity, realizes status control and storage battery energy management, protects the battery and the system runs stably.
