基于IV曲线测试的户外多通道光伏组件评测系统

摘要

为准确对户外光伏组件性能进行比对，设计了一款基于IV曲线测试的户外多通道光伏组件评测系统。系统采用便携式计算机作为上位机，与下位机6个数据采集模块和6个探头盒单元之间分别建立串口通信，实现对下位机采集数据的接受、分析和处理。本文对系统的结构、硬软件方案设计进行了介绍，对系统功能进行了实验验证，性能良好。%In order to accurately compare the performance of outd oor PV modules, a multi-channel outdoor PV test evaluation system based on the IV curve is designed. The portable computer is used as the host computer which establishes serial communications with six data acquisition modules and six probe boxes of the lower computer respectively so that the collected data in the lower computer can be accepted, analyzed and processed. The system structure, hardware and software designs are presented, and the good functions of the system are verified by experiments.
