基于PXI和LabVIEW的光伏电池模拟器的设计

摘要

The photovoltaic cell simulator was designed by using LabVIEW as software and PXIllI7 arbitrary wave- form generator and PXI8622 Data acquisition（DAQ） card as hardware. To test the effectiveness of the simulator, the experiment was conducted by changing the light intensity, temperature and load. It is shown that the simulator can make the load operate in real time exactly on output characteristic curve of PV cell even in different external conditions.%以LabVIEW为软件,以PXI1117任意波形发生器和PXI8622数据采集卡为硬件,设计了光伏电池模拟器,通过改变光照强度、温度的数值和负载的大小验证模拟器的有效性。实验结果表明光伏电池模拟器能实时准确地使负载运行在不同外界条件下光伏电池的输出特性曲线上。
