1、太陽能光伏發(fā)電論文太陽能光伏發(fā)電論文太陽能光伏發(fā)電系統(tǒng)的設(shè)計(jì)59太陽能光伏發(fā)電論文摘要太陽能發(fā)電作為一種典型的新能源發(fā)電方式具有可持續(xù)發(fā)展和綠色環(huán)保兩大優(yōu)勢。在太陽能發(fā)電的眾多課題中,三相并網(wǎng)型光伏發(fā)電具有更高的實(shí)用價(jià)值和研究意義。本文重點(diǎn)分析研究了三相并網(wǎng)型光伏發(fā)電系統(tǒng),提出一套可行的硬件選型和電路設(shè)計(jì)方案,并最終通過MATLAB仿真驗(yàn)證了硬件系統(tǒng)設(shè)計(jì)的可行性。首先本文依次研究了三相并網(wǎng)光伏發(fā)電系統(tǒng)的光伏陣列模塊、直流變換與最大功率點(diǎn)跟蹤控制模塊、逆變并網(wǎng)模塊,其中又涉及到光電幕墻的選用,以及直流變換電路、最大功率點(diǎn)跟蹤算法、逆變電路及其并網(wǎng)方式的對比選取。然后
2、選定了三相并網(wǎng)光伏發(fā)電系統(tǒng)的結(jié)構(gòu)方式,將各個(gè)模塊選取的硬件整合,并配合外圍電路和CPU控制回路的設(shè)計(jì),完成了三相并網(wǎng)光伏發(fā)電系統(tǒng)模型的整體設(shè)計(jì)。最后對硬件系統(tǒng)在MATLABSIMULINK環(huán)境下經(jīng)行仿真初探,它運(yùn)用了先進(jìn)空間矢量脈寬調(diào)制的技術(shù),驗(yàn)證了本文設(shè)計(jì)的具體可操作性。關(guān)鍵詞:光伏發(fā)電系統(tǒng);最大功率點(diǎn)跟蹤;三相逆變并網(wǎng);仿真59太陽能光伏發(fā)電論文ThedesignofsolarphotovoltaicpowergenerationsystemAbstractAsakindoftypicalgeneratingnewenergyway,solarpowerhas
