摘要
当前全球性的能源危机迫使越来越多的国家开始重视新能源的研究,光伏发电作为主要的一种方法得到了广泛研究;但由于光伏电池造价高,不利于其初期的研究.因此,很有必要设计一种成本较低,能够代替实际光伏电池阵列来执行各种光伏实验的太阳能电池模拟器.介绍了一种基于ARM控制的数字式光伏电池阵列模拟器的设计方法,这种模拟器采用STM32F103作为主控制器,可在光伏电池阵列容量一定时完成对系统数据的采集、分析、处理和实时控制.实验表明,该模拟器可以完整复现光伏电池阵列的I-U特性.
Global energy crisis compels more and more countries to attach importance to the research of new energy sources.Photovoltaic generator is now a major means that has been widely used,but the high cost of photovoltaic cells hinders the research of it in initial period.So it is necessary to design a low-cost solar battery simulator that can substitute for photovoltaic-array to conduct all kinds of photovoltaic experiments.This paper presented the design for a digital photovoltaic-array simulator based on ARM control.This simulator employs STM32F103 as the main controller which can collect,analyze,process and control the data of the system in real time with a certain capacity of the photovoltaic-array.Experiment showed that the simulator could simulate I-U characteristics of photovoltaic-array completely.
