【摘要】 随着光伏电站应用规模和区域的不断扩大，电站的监控具有越来越重要的意义，本文介绍方便、快捷的光伏电站分布式监控系统。 论文围绕如何对光伏电站运行情况实现远程数据通信及网络监控管理，介绍了系统结构、工作原理及系统实现的几种方法。 论文详细讲述了如何通过RS485串行口和数传电台与光伏电站进行数据通信以获得电站运行数据、修改电站参数；如何采取MODEM拨号方式获得这些数据而实现远程数据通信；还阐述了如何利用INTERNET技术发送这些数据到互联网上和对光伏电站运行数据进行分析、管理、显示、打印而实现网络监控管理，从而实现光伏电站的分布式监控。 本文最后对系统进行了分析，指出了需要提高和完善的地方，并对利用嵌入式INTERNET和GPRS中的短信息技术构建远程监控系统作了一定的构想。 文章主要内容包括如下几个部分： 1)光伏电站及其监控系统的发展状况和发展前景。 2)光伏电站的三种监控系统结构及其比较。 3)采用Modem拨号方式，通过串行口实现PC机和光伏电站之间的远程数据通信，包括电站运行数据的传输、存储、图形表格显示、打印等，并包括电站参数的修改。 4)基于Internet的TCP／IP协议的光伏电站网络监控系统的开发，包括电站运行数据的传输、存储、图形表格显示、打印等，并包括电站参数的修改。 5)基于ASP.NET和ADO.NET的光伏电站Internet网络远程监控的实现。包括电站运行数据的传输、存储、图形表格显示等。 6)对本文的系统做出总结，提出不足之处和改进措施。更多还原

【Abstract】 With the development of application of solar power station, it’s supervision becomes more and more important. Distributing monitor system of power stations is introduced in the paper.This paper is focused on how to monitor and control the running condition of solar power station. Structure, theories and several methods of realizing distant supervision and remote control are introduced.This paper introduced how to communicate with solar power station by serial communication in order to get the running data and edit the parameters and how to use dialing method of MODEM to get those data so as to achieve distant data communication in detail. This paper also discusses how to send data to Internet by using network technology and how to analyze, display and print those data to achieve distributing monitor system.In the end, this paper analyses the system and gives some advice for improvement.This paper includes the following:1) Development and prospect of solar power station and monitor system;2) Three projects of monitor system and their contrast3) Build good communication between W77E58 and PC through serial communication by dialing method of MODEM including transmitting and saving and displaying those running data.4) Achievement of distant supervision and remote control system based on TCP/IP of Internet including transmitting and saving and displaying those running data.5) Achievement of remote monitor system based on ASP.NET and ADO.NET including transmitting and saving and displaying those running data6) Summing up the paper and indicate drawback and improvement更多还原
