并网型光伏微网系统的3G智能监控终端设计

摘要

In this paper,a 3G intelligent monitor terminal based on the grid-connected photovoltaic system is proposed.This system includes the measurement and control unit,the 3G wireless communication module and network,and the master station.The environmental parameters of the photovoltaic system and the system parameters are got and disposed by the measurement and control unit. Then,these parameters are sent to the master station by the 3G wireless communication network.The intelligent decision is made by the master station and sent back to the measurement and control unit or the Internet users to improve electric energy and reliability of power network.%提出一种使用3G智能监控终端完成并网型光伏微网系统的监控设计方案，由测量控制单元、3G无线通信模块、3G无线通信网络、主站系统四个主要部分组成。测控单元采集光伏微网发电系统的环境参数和系统参数存储并处理，通过3G无线通信网络传送到主站，主站进行智能分析和决策并下达到测控单元，通过 Internet用户可异地实时监控，便于提高电能质量和电网运行的可靠性。
