实验室用大功率太阳能电池阵列模拟

摘要

A novel solar cell array simulation method based real-time closed-loop control of the programmable DC power supply is proposed. According to the mathematical model of the solar array and the real-time value of the out-put voltage and current of the programmable DC power supply,control program is designed to realize that the output voltage and current can simulate the output characteristics of the solar cell array by closed-loop control of the pro-grammable DC power supply. Steady and dynamic experimental studies are carried out and experimental results show that the proposed scheme has perfect steady state simulation accuracy and fast dynamic response.%本文研究了一种基于可编程直流电源实时闭环控制的太阳能电池阵列的模拟方法，实时采集可编程直流电源的输出电压和电流，编写程序对可编程直流电源进行闭环控制，使其输出电压与电流能够模拟太阳能电池阵列的输出特性。稳态和动态实验结果表明，所提出的方案具有较高的稳态模拟精度和较快的动态响应速度。
