【摘要】:以传统逐点差值比较法实现工作点跟踪的太阳电池模拟器为研究对象,通过对逐点差值比较法的实验研究,结合二分法在工作点跟踪中能快速逼近工作点的优势,提出一种混合控制算法实现快速准确地逼近工作点。在Matlab/Simulink中搭建仿真模型,验证了混合控制算法的可行性和电路的合理性。结果表明:当模拟器负载发生较大变化时,所采用的混合控制算法能够准确地逼近工作点,缩短了控制模块计算时间,并能根据负载所处不同特性曲线区间,选择合适的计算变量,提升太阳电池模拟器工作的稳定性。
[Abstract]:The traditional point-by-point difference comparison method is used to realize the work point tracking of solar cell simulator as the research object, through the point by point difference comparison method of experimental research. Combined with the advantages of dichotomy in the work point tracking can quickly approach the work point. A hybrid control algorithm is proposed to approach the working point quickly and accurately. The simulation model is built in Matlab/Simulink. The feasibility of the hybrid control algorithm and the rationality of the circuit are verified. The results show that the hybrid control algorithm can approach the working point accurately when the load of the simulator changes greatly. The calculation time of the control module is shortened and the stability of the solar cell simulator can be improved by selecting the appropriate calculation variables according to the different characteristic curve interval of the load.
