直流微電網(wǎng)光伏模擬器畢業(yè)設(shè)計(jì)

1、摘要太陽能是一種不會(huì)枯竭的綠色能源，在能源匱乏的今天受到很多國家的重視，但是對于太陽能的開發(fā)利用全人類還做的不夠。目前對太陽能的利用主要在于光伏系統(tǒng)，而光伏陣列則是光伏系統(tǒng)的核心，是實(shí)現(xiàn)太陽能到電能轉(zhuǎn)換的重要部分。但是由于光伏陣列的研究成本高、效率很低、占地面積大，這給科學(xué)研究帶來了很大的困難。本文介紹直流微電網(wǎng)與光伏模擬器的發(fā)展現(xiàn)狀及前景，了解直流微電網(wǎng)與光伏陣列的結(jié)構(gòu)與特點(diǎn)，介紹一種數(shù)字式的直流微電網(wǎng)光伏模擬器，了解這種模擬器的基本

2、原理及結(jié)構(gòu)，說明對于這種模擬器研究的必要性與經(jīng)濟(jì)性。關(guān)鍵詞：直流微電網(wǎng)；光伏模擬器；微電網(wǎng)；光伏陣列目錄1緒論......................................................................................................................11.1課題的背景及意義...................................
