光伏阵列模拟器的研究与设计

摘要

This paper presents a design method of solar array simulator based on a Programmable Power Supply (PPS). Simulation models for solar array under different Matlab environment are built up to obtain the U-I characteristics curves of the models.Then Using segmented curve-fitting technique and developing PC software to control the PPS tracking the curves.In this way,the functions of a solar array simulator are achieved by the PPS.Finally, the experimental results verify the feasibility and thevalidity of this solar array simulation system.%文中提出了一种基于可编程电源的光伏阵列模拟器实现方法，通过Matlab对其各种环境下的模型进行仿真，得到U-I特性曲线，对其进行分段拟合，并通过开发上位机软件，实现对可编程电源的控制，使其输出电压和电流跟踪该伏安特性曲线，从而实现模拟光伏阵列的功能。最终通过实验，验证了模拟系统的可行性与有效性。
