【摘要】：光伏并網(wǎng)發(fā)電的技術(shù)已經(jīng)越來越廣泛的被應(yīng)用到世界各國,在全球能源緊缺的背景下,其環(huán)保、綠色、經(jīng)濟的優(yōu)點,使得太陽能成為今后大力開發(fā)的新能源之一。作為光伏并網(wǎng)發(fā)電系統(tǒng)中最為核心的部件,逆變器的能否正常工作直接影響整個電網(wǎng)系統(tǒng)的健康運營。所以,設(shè)計出一套智能的監(jiān)控系統(tǒng)使得光伏逆變器工作在安全、高效、可控的狀態(tài)顯得尤為重要,這也是近年來光伏發(fā)電領(lǐng)域越來越重視的問題。 本文是基于ARM9平臺上嵌入Linux操作系統(tǒng)的光伏逆變器監(jiān)控的設(shè)計,通過嵌入Web服務(wù)器接入網(wǎng)絡(luò)來訪問和控制逆變器,很好的保證了逆變器安全、高效的工作。本系統(tǒng)整體的監(jiān)控框架為：光伏逆變器通過RS485總線與ARM監(jiān)控平臺相連接,在ARM平臺上嵌入Linux操作系統(tǒng)并移植Web服務(wù)器,遠(yuǎn)端監(jiān)控人員通過輸入正確的IP地址來查看和控制逆變器。 本文主要設(shè)計了監(jiān)控平臺的硬件,并在硬件平臺上搭建Linux操作系統(tǒng)的軟件平臺,并實現(xiàn)了嵌入式SQLite數(shù)據(jù)庫和Web服務(wù)器的功能。硬件設(shè)計部分主要有：電源電路、USB電路、JTAG電路、RS485接口、以太網(wǎng)接口以及擴展口電路的設(shè)計等；軟件設(shè)計包括：嵌入式Linux操作系統(tǒng)的移植、開發(fā)環(huán)境的搭建、驅(qū)動程序的編程、SQLite數(shù)據(jù)庫的移植以及Web服務(wù)器構(gòu)建的詳細(xì)過程。文章的最后還論述了應(yīng)用程序和監(jiān)控頁面設(shè)計的詳細(xì)過程。經(jīng)過系統(tǒng)測試的結(jié)果可知,本系統(tǒng)能有效的通過Web服務(wù)器訪問和控制逆變器,達(dá)到預(yù)期的目的。
[Abstract]:Photovoltaic grid-connected power generation technology has been more and more widely used in the world. Under the background of global energy shortage, the advantages of environmental protection, green and economic make solar energy become one of the new energy in the future. As the core of PV grid-connected generation system, the normal operation of inverter directly affects the healthy operation of the whole grid system. Therefore, it is very important to design a set of intelligent monitoring system to make the photovoltaic inverter work in a safe, efficient and controllable state, which is also a more and more important issue in the field of photovoltaic power generation in recent years. This paper is based on the ARM9 platform embedded Linux operating system of photovoltaic inverter monitoring design, through embedded Web server access to the network to access and control the inverter, a good guarantee of inverter security, efficient work. The whole monitoring framework of this system is as follows: photovoltaic inverter is connected to arm monitoring platform through RS485 bus, embedded Linux operating system and transplanted Web server on arm platform. Remote monitors view and control the inverter by entering the correct IP address. This paper mainly designs the hardware of the monitoring platform, and builds the software platform of Linux operating system on the hardware platform, and realizes the function of embedded SQLite database and Web server. The hardware design includes: power supply circuit, USB circuit, JTAG circuit, RS485 interface, Ethernet interface and extended port circuit, etc. Software design includes: transplant of embedded Linux operating system, construction of development environment, etc. Driver programming SQLite database migration and Web server building a detailed process. At the end of the article, the detailed process of application and monitoring page design is also discussed. The results of the system test show that the system can access and control the inverter effectively through the Web server to achieve the desired purpose.
