摘要
本课题结合科技部十五攻关课题“大型光伏并网示范电站”,以组态软件“组态王”为软件开发平台,采用集散控制思想,开发出一套并网光伏电站分布式数据采集监测系统。监测系统以RS-485总线为骨干,采用分层分布式的方式,构建了监测系统现场网络。
     监测系统软件采用模块化设计思想,以数据的获取、传输、变换、输出为主线进行程序设计。文中详细介绍了监测系统网络体系结构的建立及监测系统软件和硬件设计。
     将RS-485总线技术和分布式数据采集思想引入并网光伏电站监测系统是本课题的一个特色,并且组态软件技术、OPC技术规范和动态数据交换技术在本课题中也得到了成功应用。
     最后,对并网光伏示范电站的部分运行数据做了简要分析。
This thesis is established based on the project of "Large Scale Grid-Connected PV Program". The monitoring system software is programmed on the platform of KingView. Applying distribution control theory, the distributed data acqusition and monitoring system was developed. The system is based on RS-485 data bus.
    The monitoring software is designed under the principle of modularization. The task comprises building the network structure of monitoring system, designing hardware and software.
    The thesis features the applying of distributed data acquisition theory in the grid-connected PV system. And the monitoring system also integrates COM(Component Object Model) , OPC(OLE for Process Control) and DDE(Dynamic Data Exchange).
    Finally, this paper analyzes some performance data of grid-connected PV system.
