【摘要】：在生態(tài)環(huán)境惡化、氣候變暖、人們環(huán)保意識日益增強和全球資源消費日益緊張的大環(huán)境下,太陽能光伏產(chǎn)業(yè)必將成為可再生能源領(lǐng)域的一支主力軍。隨著光伏產(chǎn)業(yè)的發(fā)展,光伏發(fā)電市場競爭也日益激烈,特別是歐洲、美國、中國和日本等國家和地區(qū)在光伏領(lǐng)域的投資增長迅速,發(fā)電能源的份額中光伏的部分越來越大,并將逐漸取代化石能源的地位成為電力的主要來源。但是光伏發(fā)電的發(fā)展在國內(nèi)卻滯后于國外,《中國新能源政策(2012)》白皮書提出：到2015年,中國建成的光伏發(fā)電裝機容量將達到2100萬kW以上,并且根據(jù)國家能源局發(fā)布2015年上半年光伏發(fā)電建設(shè)簡況：截至2015年6月底,光伏電站共3007萬千瓦,分布式光伏為571萬千瓦,全國光伏發(fā)電裝機容量達到3578萬千瓦。但是目前光伏產(chǎn)業(yè)現(xiàn)狀急需改善,制度層面上,缺乏光伏并網(wǎng)全方位、全過程的行業(yè)標(biāo)準(zhǔn)、管理細則及政策法規(guī),并且并網(wǎng)價格的調(diào)控也不完善；技術(shù)層面上,光伏產(chǎn)業(yè)發(fā)展所急需攻克的新技術(shù)、新裝備、新材料等方面也存在很大發(fā)展空間。本文以山東成武地區(qū)為例,重點研究20MW光伏發(fā)電系統(tǒng)在接入lOkV電壓等級電網(wǎng)的設(shè)計方案。論文以光伏并網(wǎng)發(fā)電系統(tǒng)為研究對象,介紹了光伏發(fā)電背景及其現(xiàn)狀和原理,論述了并網(wǎng)光伏電源的技術(shù)特點,分析了分布式光伏系統(tǒng)的結(jié)構(gòu),及光伏組件、逆變器、最大功率點跟蹤控制,然后分別對光伏組件的選型、光伏陣列的運行方式、逆變器的選型、方陣接線方案、光伏并網(wǎng)系統(tǒng)接入電網(wǎng)、光伏電池的散熱及其光伏電站的無功補償進行了研究設(shè)計,對光伏電站的經(jīng)濟社會效益進行了分析。最后對全文進行總結(jié),并結(jié)合現(xiàn)在的研究對下一步的研究工作進行展望。
[Abstract]:With the deterioration of ecological environment, the warming of climate, the increasing awareness of environmental protection and the increasingly tight consumption of global resources, the solar photovoltaic industry will become a major force in the field of renewable energy. With the development of photovoltaic industry, the competition of photovoltaic power generation market is becoming increasingly fierce, especially in Europe, the United States, China and Japan and other countries and regions in the field of photovoltaic investment is growing rapidly, the share of power generation energy photovoltaic part of the growing. And will gradually replace the status of fossil energy as the main source of electricity. However, the development of photovoltaic power generation lags behind that of foreign countries. The white paper "China's New Energy Policy (2012)" proposes that by 2015, the installed capacity of photovoltaic power generation in China will reach more than 21 million kW. And according to the National Energy Administration, the first half of 2015 photovoltaic construction profile: by the end of June 2015, photovoltaic power plants a total of 3007 million kilowatts, distributed photovoltaic 571 million kilowatts, the installed capacity of national photovoltaic generation reached 3578 million kilowatts. However, the current situation of photovoltaic industry is in urgent need of improvement. At the system level, there is a lack of all aspects of photovoltaic grid-connected, the whole process of industry standards, management rules and policies and regulations, and the regulation of grid-connected prices is not perfect. The development of photovoltaic industry is in urgent need of new technology, new equipment, new materials and so on. Taking Chengwu area of Shandong Province as an example, this paper focuses on the design scheme of 20MW photovoltaic power system connected to lOkV voltage grade grid. This paper takes photovoltaic grid-connected generation system as the research object, introduces the background, current situation and principle of photovoltaic power generation, discusses the technical characteristics of grid-connected photovoltaic power supply, and analyzes the structure of distributed photovoltaic system, photovoltaic module and inverter. The maximum power point tracking control is followed by the selection of photovoltaic modules, the operation mode of photovoltaic arrays, the selection of inverters, the connection scheme of square arrays, and the connection of photovoltaic grid-connected systems to the power grid. The heat dissipation of photovoltaic cell and the reactive power compensation of photovoltaic power station are studied and designed, and the economic and social benefits of photovoltaic power station are analyzed. Finally, the full text is summarized, and the future research work is prospected.
