【摘要】：由于化石資源的逐漸匱乏,新能源相關(guān)研究的課題越來(lái)備受關(guān)注。太陽(yáng)能作為一種新型的清潔能源,已在世界各國(guó)科研領(lǐng)域中逐步得到了應(yīng)用。面對(duì)我國(guó)能源消耗量大而儲(chǔ)存能源相對(duì)較少等問(wèn)題,在我國(guó)開(kāi)展太陽(yáng)能發(fā)電技術(shù)研究及應(yīng)用,對(duì)我國(guó)經(jīng)濟(jì)發(fā)展和人民生活都有很重要的意義。小型戶(hù)用光伏光伏系統(tǒng)由負(fù)載類(lèi)型、光伏組件、存儲(chǔ)裝置、逆變控制系統(tǒng)構(gòu)成。由于云南無(wú)電地區(qū)地理位置復(fù)雜性,傳統(tǒng)電網(wǎng)技術(shù)難以覆蓋。而云南地區(qū)日照條件優(yōu)越,利用光伏發(fā)電技術(shù)解決無(wú)電地區(qū)人民基本用電問(wèn)題具有很大的應(yīng)用價(jià)值。首先,在太陽(yáng)能發(fā)電系統(tǒng)原理基礎(chǔ)上,本文研究了光伏發(fā)電系統(tǒng)不同類(lèi)型的結(jié)構(gòu)特點(diǎn)。依據(jù)云南地區(qū)的日照資源特性,選取適合該地區(qū)的離網(wǎng)發(fā)電系統(tǒng)類(lèi)型。其次,根據(jù)光伏電池?cái)?shù)學(xué)特性,對(duì)光伏電池在不同光照強(qiáng)度和環(huán)境溫度下進(jìn)行了模擬仿真;在蓄電池的原理的基礎(chǔ)上,研究了蓄電池充放電特性及溫度對(duì)蓄電池的影響;結(jié)合蓄電池的性質(zhì)和原理提出了改進(jìn)的蓄電池?cái)?shù)學(xué)仿真模型。本文詳細(xì)研究了小型戶(hù)用系統(tǒng)設(shè)計(jì)流程,包括負(fù)載類(lèi)型、光伏組件、蓄電池、控制器及逆變器的選取與分析。提出一種以缺電時(shí)數(shù)為指標(biāo)的光伏供電系統(tǒng)可靠度的分析,同時(shí)還研究了不同坡度屋面光伏組件的間距選取方法。以昆明地區(qū)為例,通過(guò)調(diào)查一般用戶(hù)用電需求,依據(jù)系統(tǒng)設(shè)計(jì)流程,完成了一套小型戶(hù)用光伏系統(tǒng)的設(shè)計(jì)。經(jīng)過(guò)專(zhuān)業(yè)光伏分析軟件PVSYST的仿真與分析,設(shè)計(jì)出的系統(tǒng)性能良好。本文結(jié)果可為云南無(wú)電地區(qū)建設(shè)戶(hù)用光伏系統(tǒng)中的相關(guān)問(wèn)題提供參考依據(jù)及價(jià)值。
[Abstract]:Due to the gradually lack of fossil resources, the research of new energy has attracted more and more attention. As a new clean energy, solar energy has been gradually applied in the field of scientific research all over the world. In the face of the problems of large energy consumption and relatively little energy storage in China, it is of great significance to carry out research and application of solar power generation technology in China for the economic development of our country and the life of the people. Small household photovoltaic system is composed of load type, photovoltaic module, storage device and inverter control system. Traditional power grid technology is difficult to cover due to the complexity of geographical location in Yunnan power-free area. But the sunshine condition in Yunnan area is superior, it has great application value to use photovoltaic power generation technology to solve the basic electricity problem of people in the area without electricity. Firstly, based on the principle of solar power system, this paper studies the structural characteristics of different types of photovoltaic power generation system. According to the characteristics of sunshine resources in Yunnan area, the type of off-grid power generation system suitable for this area is selected. Secondly, according to the mathematical characteristics of photovoltaic cells, the simulation of photovoltaic cells under different light intensity and ambient temperature is carried out, and on the basis of the principle of battery, the charge-discharge characteristics of battery and the effect of temperature on battery are studied. An improved mathematical simulation model of battery is proposed based on the properties and principles of battery. This paper studies the design flow of small household system in detail, including the selection and analysis of load type, photovoltaic module, battery, controller and inverter. The reliability analysis of photovoltaic power supply system based on the lack of electricity hours is presented, and the distance selection method of photovoltaic modules with different slopes is also studied. Taking Kunming area as an example, a small household photovoltaic system is designed according to the system design process by investigating the general consumer demand. Through the simulation and analysis of the professional photovoltaic analysis software PVSYST, the system has good performance. The results of this paper can provide reference and value for the related problems in the construction of household photovoltaic system in no electricity area in Yunnan Province.
