【摘要】：隨著人類生活水平的提高,人類對生存環(huán)境和能源的要求越來越高。由于化石能源的枯竭與日益嚴重的環(huán)境問題,尋找新的清潔能源已經(jīng)迫在眉睫。太陽能取之不盡,用之不竭,被認為是解決能源與環(huán)境矛盾的有效途徑之一。太陽能光伏發(fā)電零排放,零污染,已經(jīng)受到世界各國的關(guān)注和青睞。我國是太陽能光伏組件的生產(chǎn)大國,但是百分之九十以上的光伏組件出口國外,自身對光伏發(fā)電的研究和應(yīng)用很少,沒有形成完整的產(chǎn)業(yè)鏈。國家能源局發(fā)布《太陽能發(fā)電發(fā)展“十二五”規(guī)劃》指出在“十二五”期間,將大力發(fā)展光伏發(fā)電,光伏發(fā)電的應(yīng)用迎來了春天。隨著分布式發(fā)電與智能電網(wǎng)成為熱門話題,單一的大電網(wǎng)運行模式已經(jīng)不能滿足人類對電能質(zhì)量的要求,分布式電源與電網(wǎng)相結(jié)合成為一種趨勢。分布式并網(wǎng)光伏發(fā)電系統(tǒng)將成為太陽能應(yīng)用的主要發(fā)展方向。隨著大量分布式光伏發(fā)電系統(tǒng)接入電網(wǎng),將會對電網(wǎng)造成沖擊和影響。國外發(fā)達國家在分布式光伏發(fā)電領(lǐng)域已經(jīng)處于領(lǐng)先地位,然而我國對于分布式光伏發(fā)電的研究起步晚,技術(shù)相對落后。分布式光伏發(fā)電系統(tǒng)與電網(wǎng)既可以并聯(lián)運行,還可相互獨立運行,在發(fā)生故障后可快速斷開連接避免造成大面積停電事故。為了研究分布式光伏系統(tǒng)對電網(wǎng)產(chǎn)生的影響,本文在山西大學近代物理實驗室搭建了一套分布式并網(wǎng)光伏發(fā)電模型。并基于STC12C5A60S2單片機與電能芯片CS5463設(shè)計了分布式并網(wǎng)光伏發(fā)電遠程測控系統(tǒng),用戶可在不同終端查看系統(tǒng)運行狀態(tài),并可遠程控制系統(tǒng)與電網(wǎng)的連接狀態(tài),在負荷高峰期實現(xiàn)調(diào)峰的功能。系統(tǒng)中多功能雙向電表可以精準測量系統(tǒng)和電網(wǎng)之間的雙向電能以及有功功率、無功功率、功率因數(shù)、視在功率、諧波有功功率、基波有功功率和基波無功功率等信息。該系統(tǒng)不僅可做為教學儀器對學生進行光伏發(fā)電和分布式電源的教學,同時記錄分布式光伏系統(tǒng)并聯(lián)電網(wǎng)運行的數(shù)據(jù),為智能電網(wǎng)的研究提供數(shù)據(jù)支持。
[Abstract]:With the improvement of human living standard, the requirement of living environment and energy is higher and higher. Due to the depletion of fossil energy and the increasingly serious environmental problems, it is urgent to find new clean energy. Solar energy is inexhaustible and is considered to be one of the effective ways to solve the contradiction between energy and environment. Solar photovoltaic power generation zero emissions, zero pollution, has been the world's attention and favor. China is a big producer of solar photovoltaic modules, but more than 90% photovoltaic modules are exported to foreign countries, the research and application of photovoltaic power generation itself is very little, and it has not formed a complete industrial chain. The State Energy Administration has issued the 12th Five-Year Plan for the Development of Solar Power Generation, which points out that during the 12th Five-Year Plan period, photovoltaic power generation will be vigorously developed, and the application of photovoltaic power generation has ushered in spring. With distributed generation and smart grid becoming a hot topic, a single operation mode of large power grid can no longer meet the requirements of human power quality, so the combination of distributed generation and power grid has become a trend. Distributed grid-connected photovoltaic power generation system will become the main development direction of solar energy application. With a large number of distributed photovoltaic systems connected to the grid, it will impact and affect the power grid. Foreign developed countries have been in the leading position in the field of distributed photovoltaic power generation. However, the research on distributed photovoltaic power generation in China started late and the technology is relatively backward. The distributed photovoltaic power generation system and the grid can be operated in parallel and independently, which can quickly disconnect the connection after the fault and avoid large area power outages. In order to study the influence of distributed photovoltaic system on power grid, a set of distributed grid-connected photovoltaic power generation model was built in the modern physics laboratory of Shanxi University. Based on STC12C5A60S2 single chip and CS5463, a distributed photovoltaic remote measurement and control system is designed. Users can view the running state of the system at different terminals, and can remotely control the connection between the system and the power grid. The function of peak load regulation is realized during the peak load period. The multifunctional bidirectional meter can accurately measure the information of bidirectional electric energy, active power, reactive power, power factor, apparent power, harmonic active power, fundamental active power and fundamental reactive power between the system and the power network. The system can not only be used as a teaching instrument to teach students photovoltaic generation and distributed power generation, but also record the data of parallel grid operation of distributed photovoltaic system, which can provide data support for the research of smart grid.
