摘要
为解决光伏发电实验对自然条件的依赖问题,提出了一个基于DSP2812控制器的光伏阵列模拟器,并给出了软硬件设计,仿真结果证明基于逐点差值比较法的双闭环分段跟踪策略可以使模拟器的输出特性非常接近光伏阵列的工程用数学模型,并具有良好的动态响应。
In order to solve the problem of experiment ofphotovoltaic generation relying upon natural conditions, this paper raised a photovoltaic array simulator based on DSP2812 controller, giving the design of hardware and software. Simulation results show that the double-closed sectional tracking strategy based on point by point differential value comparison method can make the output charac- teristics of simulator very close to the engineering math model of photovoltaic array with fine dynamic response.
