基于物联网的太阳能光伏自跟踪发电监测系统设计

摘要

In order to improve the working efficiency of photovoltaic solar substation, it combines the advantages of Internet of things technology with a solar photovoltaic self-tracking power generation monitoring system, designs the monitoring system.It divides the system into perception layer, transmission layer and interaction layer based on the architecture of the Internet of things.The data is sent to the master node through the CAN;the master node is connected with the remote monitoring center through GPRS and the Internet.The system realizes the remote management personnel monitor to analyze the real-time data of the PV substation through the software interface.Taking the test platform it verifies the system.The test results show that the system can run stably and feedback abnormal information in time.%为提高光伏太阳能变电站的工作效率,结合物联网技术的优势,设计了一款基于物联网的太阳能光伏自跟踪发电监测系统.利用物联网架构体系,将该监测系统分为采集层、传输层和监控层.通过若干传感器对光伏阵列数据进行采集,然后通过CAN总线将数据发送给主控节点;主控节点通过GPRS和Internet网络与远程监控中心连接;远程管理人员通过软件界面对光伏变电站的运行情况进行实时监控,并对采集到的异常数据进行及时分析和处理.最后通过搭建测试平台对系统进行测试,测试结果表明,系统可及时采集和显示变电站运行信息.
