【摘要】：化石能源趋近枯竭,并已给人类生存环境造成雾霾、全球变暖等难以解决的污染问题。全球各国都正致力于开发清洁的太阳能资源。增效光伏发电系统将光热发电系统中定日镜聚光的特性应用到带有追踪功能的光伏发电系统中,可大幅度提高光太阳能利用率。但是光伏发电系统在运行过程中存在各种隐患,对人们的财产安全和生命安全造成了严重的威胁,因此对增效光伏发电系统进行监控是十分必要的。作为增效光伏发电系统中最重要的部分,定日镜的监控和控制在国内仍没有受到重视,所以开展对定日镜控制和监控的研究具有重大意义。本文分析了调研了目前太阳能的利用情况和定日镜控制系统及监控系统的发展状况,并以此为基础设计一套适用于增效光伏发电系统的定日镜控制及监控系统。该系统可实现定日镜对太阳有效的追踪和对定日镜运行状况的监控。课题以进阶精简指令集机器(ARM)和MSP430单片机为平台,分别完成了定日镜控制系统和监控终端的硬件及软件方面的设计工作。课题的里另一个工作重点是实现了定日镜和监控终端之间的射频通信组网,及监控终端和服务器之间的通用分组无线服务技术(GPRS)通信。为了验证整个系统的功能,本文设计了实验对选取的射频模块cc110L进行了功能测试,结果表明cc110L满足增效光伏发电系统中定日镜和监控终端之间的通信要求;搭建了室内测试和室外测试测试了定日镜控制系统的太阳跟踪精度,测试结果表明本课题研制的定日镜的跟踪精度满足系统设计要求;对监控终端进行了功能性测试,测试结果表明监控终端具有数据采集、故障判断、信息显示、数据存储、数据上传等功能。
[Abstract]:Fossil energy is drying up, and has caused haze, global warming and other unsolved pollution problems to human living environment.Countries around the world are working to develop clean solar energy resources.Synergistic photovoltaic power generation system applies the characteristics of sun-mirror focusing in photothermal power generation system to photovoltaic power generation system with tracking function, which can greatly improve the utilization ratio of photovoltaic energy.However, there are various hidden dangers in the operation of photovoltaic power generation system, which pose a serious threat to the safety of people's property and life, so it is necessary to monitor and control the photovoltaic power generation system.As the most important part of the photovoltaic power generation system, the monitoring and control of the helioscope has not been paid attention to in China, so it is of great significance to carry out the research on the control and monitoring of the solar mirror.In this paper, the utilization of solar energy and the development of helioscope control system and monitoring system are analyzed, and a set of solar mirror control and monitoring system is designed based on it.The system can effectively track the sun and monitor the running condition of the helioscope.The hardware and software of the helioscope control system and the monitoring terminal are designed on the platform of Advanced RISC (ARM) and MSP430 microcontroller respectively.Another focus of the project is to realize the radio frequency communication networking between the helioscope and the monitoring terminal, and the communication between the monitoring terminal and the server using the general packet radio service technology (GPRS).In order to verify the function of the whole system, this paper designs an experiment to test the function of the selected RF module cc110L. The results show that the cc110L meets the communication requirements between the helioscope and the monitoring terminal in the synergistic photovoltaic power generation system.Indoor and outdoor tests have been built to test the sun tracking accuracy of the helioscope control system. The test results show that the tracking accuracy of the sunspot mirror developed in this paper meets the design requirements of the system, and the functional test of the monitoring terminal is carried out.The test results show that the monitoring terminal has the functions of data acquisition, fault judgment, information display, data storage, data upload and so on.
