山東省青(qing)州市魯東機械2.1MW光伏發(fa)電站(zhan)項(xiang)目。彩鋼(gang)瓦屋(wu)頂光伏發(fa)電站(zhan)，已并網(wang)發(fa)電成(cheng)功！

輸送方式

太陽能光(guang)(guang)伏(fu)發(fa)電(dian)分為獨(du)立光(guang)(guang)伏(fu)發(fa)電(dian)、并網光(guang)(guang)伏(fu)發(fa)電(dian)、分布式光(guang)(guang)伏(fu)發(fa)電(dian)

獨立光伏發電

獨立光伏發電系統(tong)(tong)也叫離網(wang)光伏發電系統(tong)(tong)。主要由太陽能電池(chi)組件、控制器、蓄(xu)電池(chi)組成，若要為交(jiao)(jiao)流負載供電，還需(xu)要配置(zhi)交(jiao)(jiao)流逆(ni)變器。

并網光伏發電

并(bing)網(wang)光(guang)伏發(fa)(fa)(fa)(fa)電(dian)(dian)(dian)系(xi)統(tong)就是(shi)太陽能組件產生的(de)(de)直流(liu)電(dian)(dian)(dian)經(jing)過并(bing)網(wang)逆變器轉(zhuan)換成符(fu)合市電(dian)(dian)(dian)電(dian)(dian)(dian)網(wang)要求的(de)(de)交(jiao)流(liu)電(dian)(dian)(dian)之后(hou)直接(jie)(jie)接(jie)(jie)入(ru)公共(gong)電(dian)(dian)(dian)網(wang)。并(bing)網(wang)光(guang)伏發(fa)(fa)(fa)(fa)電(dian)(dian)(dian)系(xi)統(tong)有集中式大型并(bing)網(wang)光(guang)伏電(dian)(dian)(dian)站一(yi)般都是(shi)國家級電(dian)(dian)(dian)站，主要特點(dian)是(shi)將所發(fa)(fa)(fa)(fa)電(dian)(dian)(dian)能直接(jie)(jie)輸(shu)送到電(dian)(dian)(dian)網(wang)，由(you)電(dian)(dian)(dian)網(wang)統(tong)一(yi)調配向用戶供(gong)電(dian)(dian)(dian)。但這種電(dian)(dian)(dian)站投資大、建(jian)設(she)周期長、占地(di)面積大，發(fa)(fa)(fa)(fa)展難度相(xiang)對較大。而分散式小(xiao)型并(bing)網(wang)光(guang)伏系(xi)統(tong)，特別是(shi)光(guang)伏建(jian)筑一(yi)體化發(fa)(fa)(fa)(fa)電(dian)(dian)(dian)系(xi)統(tong)，由(you)于投資小(xiao)、建(jian)設(she)快、占地(di)面積小(xiao)、政策支持力度大等優(you)點(dian)，是(shi)并(bing)網(wang)光(guang)伏發(fa)(fa)(fa)(fa)電(dian)(dian)(dian)的(de)(de)主流(liu)。

分布式光伏發電

分布(bu)式(shi)光(guang)伏發(fa)(fa)電系(xi)統，又(you)稱分散(san)式(shi)發(fa)(fa)電或分布(bu)式(shi)供(gong)能，是(shi)指在(zai)用戶現場或靠(kao)近用電現場配置(zhi)較小的(de)(de)光(guang)伏發(fa)(fa)電供(gong)電系(xi)統，以滿足特定(ding)用戶的(de)(de)需求，支持現存配電網的(de)(de)經(jing)濟運行，或者(zhe)同(tong)時滿足這兩個方面的(de)(de)要(yao)求。

　　分布式光伏發(fa)電(dian)(dian)(dian)(dian)系(xi)(xi)(xi)統的(de)基(ji)本設(she)備包(bao)括光伏電(dian)(dian)(dian)(dian)池(chi)組件、光伏方陣支架(jia)、直(zhi)流(liu)匯流(liu)箱、直(zhi)流(liu)配(pei)電(dian)(dian)(dian)(dian)柜(ju)、并(bing)網(wang)逆變器、交流(liu)配(pei)電(dian)(dian)(dian)(dian)柜(ju)等設(she)備，另外還(huan)有供電(dian)(dian)(dian)(dian)系(xi)(xi)(xi)統監控裝(zhuang)置和環境監測裝(zhuang)置。其運行(xing)模式是在有太陽(yang)輻射的(de)條件下(xia)，光伏發(fa)電(dian)(dian)(dian)(dian)系(xi)(xi)(xi)統的(de)太陽(yang)能(neng)電(dian)(dian)(dian)(dian)池(chi)組件陣列(lie)將太陽(yang)能(neng)轉換(huan)輸出(chu)的(de)電(dian)(dian)(dian)(dian)能(neng)，經過直(zhi)流(liu)匯流(liu)箱集中送(song)入直(zhi)流(liu)配(pei)電(dian)(dian)(dian)(dian)柜(ju)，由并(bing)網(wang)逆變器逆變成交流(liu)電(dian)(dian)(dian)(dian)供給建筑自身負(fu)載，多余或不足的(de)電(dian)(dian)(dian)(dian)力通(tong)過聯接電(dian)(dian)(dian)(dian)網(wang)來調節。
