【摘要】:太陽(yáng)能是資源最豐富的可再生能源之一,光伏發(fā)電技術(shù)為利用太陽(yáng)能提供了一個(gè)廣闊的舞臺(tái)。與核電、火電相比,光伏發(fā)電幅員遼闊,分布不集中,不利于監(jiān)測(cè)數(shù)據(jù)和統(tǒng)計(jì)數(shù)據(jù)。為了避免查看分布式光伏電站信息所帶來(lái)的人力物力財(cái)力浪費(fèi),保證光伏電站安全可靠運(yùn)行,研究光伏電站監(jiān)控系統(tǒng)具有重要意義。 本文針對(duì)小型戶(hù)用光伏電站項(xiàng)目,設(shè)計(jì)了一套戶(hù)用光伏電站監(jiān)控系統(tǒng),利用Delphi7.0軟件設(shè)計(jì)上位機(jī)人機(jī)交互界面,對(duì)現(xiàn)場(chǎng)采集的數(shù)據(jù)進(jìn)行顯示、統(tǒng)計(jì)和分類(lèi),并對(duì)故障信息做出報(bào)警提示,確保戶(hù)用光伏電站的安全運(yùn)行。使用SQL Server2000數(shù)據(jù)庫(kù)存儲(chǔ)下位機(jī)傳送給上位機(jī)的數(shù)據(jù)。 本文主要工作如下: (1)闡述了本文的研究背景,,對(duì)國(guó)內(nèi)外光伏電站監(jiān)控系統(tǒng)的現(xiàn)狀和發(fā)展做了具體分析,闡述了本文的重要意義。 (2)介紹了開(kāi)發(fā)環(huán)境和數(shù)據(jù)庫(kù)的選取,確定了本文所研究的戶(hù)用光伏電站監(jiān)控系統(tǒng)的功能需求和特點(diǎn),給出系統(tǒng)的功能模塊圖,建立了數(shù)據(jù)庫(kù)系統(tǒng)。 (3)開(kāi)發(fā)各個(gè)功能模塊的用戶(hù)界面。 (4)介紹了通信方式的選擇,制定了Modbus通信協(xié)議,利用Delphi串行通信控件Spcomm設(shè)計(jì)系統(tǒng)的通信模塊。 (5)進(jìn)行了系統(tǒng)功能性測(cè)試,實(shí)驗(yàn)結(jié)果表明,本文所開(kāi)發(fā)的戶(hù)用光伏電站監(jiān)控系統(tǒng)達(dá)到了預(yù)期目的,可通過(guò)RS-485總線進(jìn)行上下位機(jī)間通訊并實(shí)時(shí)顯示在上位機(jī)監(jiān)控界面中,驗(yàn)證了設(shè)計(jì)的正確性和可行性。
[Abstract]:Solar energy is one of the most abundant renewable energy, photovoltaic technology provides a broad stage for the use of solar energy. Compared with nuclear power and thermal power, photovoltaic power generation is vast and not concentrated, which is not conducive to monitoring data and statistical data. In order to avoid the waste of manpower, material and financial resources brought by the distributed photovoltaic power station information, and to ensure the safe and reliable operation of photovoltaic power station, it is of great significance to study the monitoring system of photovoltaic power station. In this paper, a monitoring system of household photovoltaic power station is designed for the small household photovoltaic power station project. The man-machine interface of upper computer is designed by Delphi 7.0 software, and the data collected in the field are displayed, counted and classified. The fault information is alerted to ensure the safe operation of the household photovoltaic power station. SQL Server 2000 database is used to store the data transferred from the lower computer to the upper computer. The main work of this paper is as follows: (1) the research background of this paper is described, and the current situation and development of photovoltaic power station monitoring system at home and abroad are analyzed concretely. The important significance of this paper is expounded. (2) the selection of development environment and database is introduced, the functional requirements and characteristics of the monitoring system of household photovoltaic power station studied in this paper are determined, and the function module diagram of the system is given. The database system is established. (3) the user interface of each functional module is developed. (4) the choice of communication mode is introduced, and the Modbus communication protocol is established. Using Delphi serial communication control Spcomm to design the communication module of the system. (5) the functional test of the system is carried out. The experimental results show that the monitoring system of the household photovoltaic power station developed in this paper has achieved the expected purpose. The communication between upper and lower computers can be carried out by RS-485 bus, and it can be displayed in the monitor interface of upper computer in real time. The correctness and feasibility of the design are verified.
