山(shan)東省青州市魯(lu)東機械2.1MW光伏發電站(zhan)(zhan)項目。彩(cai)鋼瓦屋頂光伏發電站(zhan)(zhan)，已并(bing)網(wang)發電成功！

輸送方式

太陽能光(guang)伏(fu)發電分為獨立光(guang)伏(fu)發電、并網光(guang)伏(fu)發電、分布(bu)式光(guang)伏(fu)發電

獨立光伏發電

獨立光(guang)伏發電系(xi)統也叫離網光(guang)伏發電系(xi)統。主要(yao)由太(tai)陽能電池組(zu)件、控制(zhi)器、蓄電池組(zu)成，若要(yao)為(wei)交流負載供電，還(huan)需要(yao)配置交流逆變(bian)器。

并網光伏發電

并網(wang)(wang)光(guang)(guang)伏(fu)(fu)發電(dian)(dian)系(xi)統(tong)(tong)就是(shi)太陽能(neng)組件產(chan)生的(de)直(zhi)流(liu)(liu)電(dian)(dian)經(jing)過(guo)并網(wang)(wang)逆變(bian)器轉換成符合市電(dian)(dian)電(dian)(dian)網(wang)(wang)要求的(de)交(jiao)流(liu)(liu)電(dian)(dian)之(zhi)后直(zhi)接接入公共電(dian)(dian)網(wang)(wang)。并網(wang)(wang)光(guang)(guang)伏(fu)(fu)發電(dian)(dian)系(xi)統(tong)(tong)有集中式大型(xing)并網(wang)(wang)光(guang)(guang)伏(fu)(fu)電(dian)(dian)站(zhan)一(yi)(yi)般都是(shi)國家級電(dian)(dian)站(zhan)，主(zhu)要特點是(shi)將所發電(dian)(dian)能(neng)直(zhi)接輸送到電(dian)(dian)網(wang)(wang)，由電(dian)(dian)網(wang)(wang)統(tong)(tong)一(yi)(yi)調配(pei)向(xiang)用戶供電(dian)(dian)。但(dan)這種電(dian)(dian)站(zhan)投(tou)資(zi)大、建(jian)設周(zhou)期長(chang)、占地(di)面(mian)積大，發展難(nan)度相對較(jiao)大。而分散式小(xiao)型(xing)并網(wang)(wang)光(guang)(guang)伏(fu)(fu)系(xi)統(tong)(tong)，特別是(shi)光(guang)(guang)伏(fu)(fu)建(jian)筑(zhu)一(yi)(yi)體(ti)化(hua)發電(dian)(dian)系(xi)統(tong)(tong)，由于(yu)投(tou)資(zi)小(xiao)、建(jian)設快、占地(di)面(mian)積小(xiao)、政策支持力度大等優點，是(shi)并網(wang)(wang)光(guang)(guang)伏(fu)(fu)發電(dian)(dian)的(de)主(zhu)流(liu)(liu)。

分布式光伏發電

分(fen)布(bu)式(shi)(shi)光(guang)伏發(fa)電(dian)(dian)系統(tong)，又(you)稱分(fen)散式(shi)(shi)發(fa)電(dian)(dian)或分(fen)布(bu)式(shi)(shi)供(gong)能，是(shi)指在用(yong)戶(hu)現(xian)場(chang)或靠近用(yong)電(dian)(dian)現(xian)場(chang)配(pei)置較(jiao)小(xiao)的(de)(de)光(guang)伏發(fa)電(dian)(dian)供(gong)電(dian)(dian)系統(tong)，以滿(man)足特定用(yong)戶(hu)的(de)(de)需求，支持現(xian)存配(pei)電(dian)(dian)網的(de)(de)經濟運行，或者同時滿(man)足這兩個方面(mian)的(de)(de)要求。

　　分(fen)布式光伏(fu)發電(dian)(dian)(dian)系統的(de)(de)基本(ben)設備包(bao)括光伏(fu)電(dian)(dian)(dian)池組(zu)件(jian)、光伏(fu)方陣支架、直流(liu)(liu)匯流(liu)(liu)箱、直流(liu)(liu)配(pei)電(dian)(dian)(dian)柜(ju)、并網(wang)逆變器、交流(liu)(liu)配(pei)電(dian)(dian)(dian)柜(ju)等設備，另外(wai)還有(you)供電(dian)(dian)(dian)系統監(jian)控裝(zhuang)置和環境監(jian)測裝(zhuang)置。其運行模式是在有(you)太陽輻射(she)的(de)(de)條件(jian)下，光伏(fu)發電(dian)(dian)(dian)系統的(de)(de)太陽能(neng)電(dian)(dian)(dian)池組(zu)件(jian)陣列將太陽能(neng)轉換輸(shu)出的(de)(de)電(dian)(dian)(dian)能(neng)，經過直流(liu)(liu)匯流(liu)(liu)箱集中送入直流(liu)(liu)配(pei)電(dian)(dian)(dian)柜(ju)，由(you)并網(wang)逆變器逆變成交流(liu)(liu)電(dian)(dian)(dian)供給建筑自身(shen)負載，多余或不足的(de)(de)電(dian)(dian)(dian)力通過聯(lian)接電(dian)(dian)(dian)網(wang)來調節。
