摘　　要：目前光伏发电已经进入智能化管理阶段,其中的检测工作主要由汇流箱完成,检测电流、电压以及温湿度等信息。然而汇流箱只能检测串联回路单元,具体哪块光伏组件出现问题,则需要检修人员拿万用表到现场测量。设计了一种分布式光伏发电的检测管理系统,能够检测每块光伏组件,并且检测模块是嵌入在光伏组件的接线盒里,减少施工安装工作。采集的数据以无线方式传输给汇流箱,汇流箱再通过RS-485等方式将数据传输到上位机,由上位机查看发电情况,以及判断光伏组件是否正常发电。So far, photovohaic power generation has stepped into intelligent management stage, and the detection work including detecting current, voltage, temperature and humidity is mostly done by combiner box. However, combiner box can only detect series circuit, and maintenance personnel should take a multimeter to find out which photovohaic module is bad. This paper designed a detection management system of distributed photovoltaic power generation, which can detect each photovohaic module, and the detection module is embedded in the junction box of photovoltaic module, reducing installation work. The collected data is transmitted to junction box in wireless way, and to upper computer through RS-485 and other ways. Upper computer can view the status of power generation, and judge whether a photovohaic module is normal.
