山(shan)東省青州市魯東機械2.1MW光伏發電站項目。彩鋼(gang)瓦屋(wu)頂光伏發電站，已(yi)并網(wang)發電成功！

輸送方式

太陽能(neng)光(guang)(guang)(guang)伏發(fa)電(dian)分(fen)為(wei)獨立光(guang)(guang)(guang)伏發(fa)電(dian)、并網光(guang)(guang)(guang)伏發(fa)電(dian)、分(fen)布式光(guang)(guang)(guang)伏發(fa)電(dian)

獨立光伏發電

獨立光(guang)伏發電(dian)(dian)(dian)(dian)系統(tong)也叫(jiao)離網(wang)光(guang)伏發電(dian)(dian)(dian)(dian)系統(tong)。主要由太(tai)陽能電(dian)(dian)(dian)(dian)池組件、控制器、蓄電(dian)(dian)(dian)(dian)池組成，若要為(wei)交流(liu)負載供電(dian)(dian)(dian)(dian)，還需(xu)要配置(zhi)交流(liu)逆(ni)變器。

并網光伏發電

并(bing)(bing)網光(guang)(guang)伏(fu)發(fa)(fa)電(dian)(dian)(dian)系(xi)(xi)統(tong)就是太(tai)陽能組件產生的(de)直流(liu)(liu)電(dian)(dian)(dian)經過并(bing)(bing)網逆變器轉換成符(fu)合(he)市電(dian)(dian)(dian)電(dian)(dian)(dian)網要(yao)(yao)求的(de)交流(liu)(liu)電(dian)(dian)(dian)之(zhi)后直接(jie)接(jie)入公共電(dian)(dian)(dian)網。并(bing)(bing)網光(guang)(guang)伏(fu)發(fa)(fa)電(dian)(dian)(dian)系(xi)(xi)統(tong)有集中式大型并(bing)(bing)網光(guang)(guang)伏(fu)電(dian)(dian)(dian)站(zhan)(zhan)一般都是國家級(ji)電(dian)(dian)(dian)站(zhan)(zhan)，主(zhu)要(yao)(yao)特點(dian)是將(jiang)所發(fa)(fa)電(dian)(dian)(dian)能直接(jie)輸送到(dao)電(dian)(dian)(dian)網，由電(dian)(dian)(dian)網統(tong)一調(diao)配向用戶供(gong)電(dian)(dian)(dian)。但(dan)這種(zhong)電(dian)(dian)(dian)站(zhan)(zhan)投(tou)資(zi)大、建設周期長、占(zhan)(zhan)地(di)面積(ji)大，發(fa)(fa)展難度相對(dui)較大。而分(fen)散式小(xiao)(xiao)型并(bing)(bing)網光(guang)(guang)伏(fu)系(xi)(xi)統(tong)，特別是光(guang)(guang)伏(fu)建筑(zhu)一體化發(fa)(fa)電(dian)(dian)(dian)系(xi)(xi)統(tong)，由于投(tou)資(zi)小(xiao)(xiao)、建設快、占(zhan)(zhan)地(di)面積(ji)小(xiao)(xiao)、政策(ce)支持力度大等優點(dian)，是并(bing)(bing)網光(guang)(guang)伏(fu)發(fa)(fa)電(dian)(dian)(dian)的(de)主(zhu)流(liu)(liu)。

分布式光伏發電

分布式光伏發(fa)電(dian)(dian)系(xi)(xi)統，又稱分散(san)式發(fa)電(dian)(dian)或(huo)分布式供(gong)能，是指在用戶現場或(huo)靠近用電(dian)(dian)現場配置(zhi)較小的(de)(de)光伏發(fa)電(dian)(dian)供(gong)電(dian)(dian)系(xi)(xi)統，以滿足(zu)特定(ding)用戶的(de)(de)需求，支持(chi)現存配電(dian)(dian)網的(de)(de)經濟運行，或(huo)者同時滿足(zu)這(zhe)兩個方面的(de)(de)要求。

　　分布(bu)式光(guang)伏(fu)(fu)發電(dian)(dian)系統的(de)基本設備包括(kuo)光(guang)伏(fu)(fu)電(dian)(dian)池(chi)組(zu)(zu)件(jian)、光(guang)伏(fu)(fu)方陣支架(jia)、直(zhi)流(liu)匯(hui)(hui)流(liu)箱、直(zhi)流(liu)配(pei)電(dian)(dian)柜、并(bing)網逆(ni)變器、交流(liu)配(pei)電(dian)(dian)柜等設備，另外還有(you)供電(dian)(dian)系統監控裝(zhuang)置和環境監測裝(zhuang)置。其運行模式是在有(you)太陽(yang)輻射的(de)條件(jian)下，光(guang)伏(fu)(fu)發電(dian)(dian)系統的(de)太陽(yang)能電(dian)(dian)池(chi)組(zu)(zu)件(jian)陣列將太陽(yang)能轉(zhuan)換(huan)輸出(chu)的(de)電(dian)(dian)能，經(jing)過(guo)直(zhi)流(liu)匯(hui)(hui)流(liu)箱集中(zhong)送入直(zhi)流(liu)配(pei)電(dian)(dian)柜，由并(bing)網逆(ni)變器逆(ni)變成交流(liu)電(dian)(dian)供給建筑自(zi)身負載，多(duo)余或(huo)不足(zu)的(de)電(dian)(dian)力通過(guo)聯(lian)接電(dian)(dian)網來調(diao)節。
