摘要
针对现有最大功率点跟踪(MPPT)方法的动态性能和稳态性能难以兼顾的难题,提出一种具有最优步长的最速下降MPPT算法,并使用上述算法对Boost DC/DC变换器进行相应控制,以达到对光伏电池输出功率进行有效调节的目的。对系统进行了Matlab/SIMULINK仿真,并在基于TM320F2812为核心控制芯片的硬件电路上进行实验。实验结果表明,该系统能较快地跟踪太阳能最大功率点,同时具有良好的稳态性能。
To solve the problem of combining dynamic property and steadystate performance into current approach of maximum power point tracking （MPPT）, it proposes an algorithm with optimed step size and steepest descend method in photovohaic system, which is to control the Boost DC/DC transducers and ad just the output power of photovoltaic cell. It simulated the system by Matlab/SIMULINK, and implemented the practical test based on the hardware circuit with the core control chipTM320P2812. It shows that this system traces the solar maximum power point as far as possible, and has steadystate performance.
