摘要 当今世界,由于能源短缺,人们将目光更多的转向了风能,水能,太阳能等可再生资源上。太阳能有资源丰富、不污染环境、可以再生、分布广泛等诸多优点,已经是国际社会公认的理想替代能源,所以开发利用太阳能来发电受到越来越普遍的重视。本文以太阳能发电的监控系统为对象,深入研究了太阳能发电监控系统的原理与电路设计等,并在此基础上一步优化了太阳能光伏电站智能监控系统,使其能够更好的实现检测的功能。
首先,本文分析了太阳能光伏系统的组成,介绍了光伏电站及电站监控系统的研究现状,提出了本文主要的研究任务。
其次,本文简单地介绍了整个光伏发电系统的构成及运行原理,详细的论述了MPPT,逆变器及其各种拓扑结构,储能装置的分类及优点和注意事项。提出了智能电站的设计理念。
然后,本文针对太阳能光伏电站监控系统,列举了现场层,中转层和监控中心的硬件选择。例如在太阳能电池阵列模块使用的是深圳圣斯尔公司CE系列光伏汇流采集装置等。数据传输采用了RS485通讯协议,AT89S51单片机的串口通信作为现场层与中转层的联系,而中转层与监控中心之间是PC机与PC机基于MODEM的通信
最后,本文详细的论述了监控系统的软件部分,从现场层单片机的编程到中转层与监控中心的数据显示和存储都做了介绍。在数据的存储部分,主要讲解了利用Visual C++与数据库的连接来存取数据,这种方式是基于Windows底层的编程,所以具有应用的广泛性。

Research on solar photovoltaic power plant monitoring system
Abstract :Due to the energy shortage,more and more people turn their eyes on wind, water, solar and other renewable resources In today's world.There are abundant solar energy resources on the earth and it was pollution free, renewable ,widely distributed and many other advantages which has been recognized as an ideal alternative energy by the international community. Therefore, the increasing of people pay their attention to the development and utilization of solar energy to generate electricity .In this paper, we choose the monitoring system of solar power as an object, studying the theory and circuit design of the solar power monitoring system deeply. And optimize the solar photovoltaic power station intelligent monitoring system so that it can better achieve detection function.
First of all, the paper analyzes the composition of the solar photovoltaic system, Introduces the research status of photovoltaic power plants and power plant monitoring system and proposes major research tasks of this article.
Secondly, the paper describes the structure and operation principle of the photovoltaic power generation system briefly, introduces the advantages of MPPT, inverters and various topologies, energy storage devices and precautions in detail an proposes concept of Intelligent power plant.
Then, this paper counter the local layer, the transfer layer and the monitoring center of solar photovoltaic power plant monitoring system. For example, solar cell array module use CE series photovoltaic from SHEN ZHEN SENSOR ELECTRONIC TECHNOLOGY CO.LTD. Data transmission using the RS485 communication protocol. AT89S51 microcontroller serial communication layer and the transfer layer as the site of contact.The transfer layer between the monitoring center PC communication with a PC-based MODEM.
Finally, the paper discusses in detail the software part of the monitoring system, makes the introduction from the field level microcontroller programming to transfer data layer and the control center display and storage.In the portion of the data storage, mainly on the use of Visual C + + and the number of connections to the database to save the data, this approach is based on the underlying Windows programming, and therefore have extensive applications.
