山東(dong)省青州市魯東(dong)機械2.1MW光伏發(fa)電站項(xiang)目。彩(cai)鋼瓦屋頂光伏發(fa)電站，已并網發(fa)電成功！

輸送方式

太(tai)陽能光伏發(fa)電(dian)分(fen)為獨立光伏發(fa)電(dian)、并(bing)網光伏發(fa)電(dian)、分(fen)布式光伏發(fa)電(dian)

獨立光伏發電

獨立光(guang)伏發電(dian)系統(tong)(tong)也叫(jiao)離(li)網(wang)光(guang)伏發電(dian)系統(tong)(tong)。主要(yao)由太陽能電(dian)池組(zu)件、控制器、蓄電(dian)池組(zu)成，若要(yao)為(wei)交(jiao)流負載供電(dian)，還需要(yao)配置交(jiao)流逆(ni)變器。

并網光伏發電

并(bing)網(wang)(wang)光(guang)(guang)伏(fu)發(fa)(fa)電(dian)(dian)(dian)(dian)系(xi)統(tong)就是(shi)太陽能組件產生的直(zhi)流(liu)電(dian)(dian)(dian)(dian)經過(guo)并(bing)網(wang)(wang)逆變器轉換成符合(he)市(shi)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)網(wang)(wang)要求的交流(liu)電(dian)(dian)(dian)(dian)之(zhi)后(hou)直(zhi)接接入公共電(dian)(dian)(dian)(dian)網(wang)(wang)。并(bing)網(wang)(wang)光(guang)(guang)伏(fu)發(fa)(fa)電(dian)(dian)(dian)(dian)系(xi)統(tong)有集中式大(da)型并(bing)網(wang)(wang)光(guang)(guang)伏(fu)電(dian)(dian)(dian)(dian)站一(yi)般(ban)都是(shi)國家級電(dian)(dian)(dian)(dian)站，主要特點是(shi)將所發(fa)(fa)電(dian)(dian)(dian)(dian)能直(zhi)接輸(shu)送到電(dian)(dian)(dian)(dian)網(wang)(wang)，由電(dian)(dian)(dian)(dian)網(wang)(wang)統(tong)一(yi)調(diao)配向(xiang)用戶供電(dian)(dian)(dian)(dian)。但這(zhe)種電(dian)(dian)(dian)(dian)站投(tou)資大(da)、建設(she)(she)周期長、占地面(mian)積大(da)，發(fa)(fa)展(zhan)難度相對較大(da)。而分散式小(xiao)型并(bing)網(wang)(wang)光(guang)(guang)伏(fu)系(xi)統(tong)，特別是(shi)光(guang)(guang)伏(fu)建筑一(yi)體(ti)化(hua)發(fa)(fa)電(dian)(dian)(dian)(dian)系(xi)統(tong)，由于投(tou)資小(xiao)、建設(she)(she)快、占地面(mian)積小(xiao)、政策支持力度大(da)等優點，是(shi)并(bing)網(wang)(wang)光(guang)(guang)伏(fu)發(fa)(fa)電(dian)(dian)(dian)(dian)的主流(liu)。

分布式光伏發電

分布(bu)式(shi)光(guang)伏發電(dian)系(xi)統，又稱分散式(shi)發電(dian)或(huo)(huo)分布(bu)式(shi)供(gong)(gong)能，是(shi)指(zhi)在用戶(hu)現(xian)場(chang)或(huo)(huo)靠近用電(dian)現(xian)場(chang)配(pei)置(zhi)較小的光(guang)伏發電(dian)供(gong)(gong)電(dian)系(xi)統，以(yi)滿足特(te)定用戶(hu)的需求(qiu)，支持現(xian)存配(pei)電(dian)網的經濟運行，或(huo)(huo)者同時滿足這兩(liang)個方(fang)面(mian)的要求(qiu)。

　　分布式光伏發電(dian)(dian)系(xi)(xi)統的(de)基本設備(bei)包括光伏電(dian)(dian)池組(zu)件、光伏方(fang)陣支架、直流(liu)匯流(liu)箱(xiang)、直流(liu)配電(dian)(dian)柜(ju)、并(bing)網逆(ni)變(bian)器、交流(liu)配電(dian)(dian)柜(ju)等設備(bei)，另外還有(you)供電(dian)(dian)系(xi)(xi)統監控(kong)裝(zhuang)置(zhi)和環境監測(ce)裝(zhuang)置(zhi)。其運行模式是在有(you)太(tai)(tai)陽輻射的(de)條件下，光伏發電(dian)(dian)系(xi)(xi)統的(de)太(tai)(tai)陽能(neng)電(dian)(dian)池組(zu)件陣列將(jiang)太(tai)(tai)陽能(neng)轉換輸出(chu)的(de)電(dian)(dian)能(neng)，經過(guo)直流(liu)匯流(liu)箱(xiang)集中送入直流(liu)配電(dian)(dian)柜(ju)，由并(bing)網逆(ni)變(bian)器逆(ni)變(bian)成交流(liu)電(dian)(dian)供給建筑自身負載，多(duo)余或不足(zu)的(de)電(dian)(dian)力通過(guo)聯接電(dian)(dian)網來(lai)調(diao)節。
