山東省青州市魯東機械2.1MW光(guang)伏(fu)發(fa)(fa)電站(zhan)項目(mu)。彩鋼瓦屋頂光(guang)伏(fu)發(fa)(fa)電站(zhan)，已并網發(fa)(fa)電成功！

輸送方式

太陽能(neng)光(guang)伏(fu)發電(dian)分為獨(du)立(li)光(guang)伏(fu)發電(dian)、并網光(guang)伏(fu)發電(dian)、分布式光(guang)伏(fu)發電(dian)

獨立光伏發電

獨立光伏發(fa)電系統也叫(jiao)離網光伏發(fa)電系統。主要由太陽能電池組件、控制器(qi)、蓄(xu)電池組成，若要為交(jiao)流(liu)負載供電，還需要配置交(jiao)流(liu)逆變器(qi)。

并網光伏發電

并網光伏發(fa)(fa)電(dian)(dian)(dian)系(xi)(xi)統(tong)(tong)(tong)就是(shi)太陽能組件產生的(de)直(zhi)流電(dian)(dian)(dian)經過并網逆變器(qi)轉換成符合市(shi)電(dian)(dian)(dian)電(dian)(dian)(dian)網要(yao)求(qiu)的(de)交流電(dian)(dian)(dian)之后直(zhi)接接入公共電(dian)(dian)(dian)網。并網光伏發(fa)(fa)電(dian)(dian)(dian)系(xi)(xi)統(tong)(tong)(tong)有集(ji)中式大(da)型并網光伏電(dian)(dian)(dian)站(zhan)一(yi)般都是(shi)國家級(ji)電(dian)(dian)(dian)站(zhan)，主要(yao)特(te)點是(shi)將所發(fa)(fa)電(dian)(dian)(dian)能直(zhi)接輸送到電(dian)(dian)(dian)網，由(you)電(dian)(dian)(dian)網統(tong)(tong)(tong)一(yi)調配向用戶供電(dian)(dian)(dian)。但這種電(dian)(dian)(dian)站(zhan)投資(zi)大(da)、建設周(zhou)期(qi)長、占地面(mian)積(ji)大(da)，發(fa)(fa)展難度(du)相對較大(da)。而(er)分散式小(xiao)型并網光伏系(xi)(xi)統(tong)(tong)(tong)，特(te)別是(shi)光伏建筑一(yi)體化發(fa)(fa)電(dian)(dian)(dian)系(xi)(xi)統(tong)(tong)(tong)，由(you)于投資(zi)小(xiao)、建設快、占地面(mian)積(ji)小(xiao)、政(zheng)策(ce)支持力(li)度(du)大(da)等優(you)點，是(shi)并網光伏發(fa)(fa)電(dian)(dian)(dian)的(de)主流。

分布式光伏發電

分布式光伏發(fa)電(dian)系(xi)統，又稱分散式發(fa)電(dian)或分布式供能，是指在用(yong)戶現(xian)場(chang)或靠近用(yong)電(dian)現(xian)場(chang)配置較小的光伏發(fa)電(dian)供電(dian)系(xi)統，以(yi)滿(man)足特定用(yong)戶的需求(qiu)(qiu)，支持現(xian)存配電(dian)網的經(jing)濟運行(xing)，或者(zhe)同時滿(man)足這(zhe)兩個方面的要(yao)求(qiu)(qiu)。

　　分(fen)布式光(guang)伏(fu)發電(dian)(dian)(dian)系(xi)統(tong)的基本(ben)設備包括(kuo)光(guang)伏(fu)電(dian)(dian)(dian)池組件、光(guang)伏(fu)方陣支架、直流匯流箱(xiang)(xiang)、直流配(pei)(pei)電(dian)(dian)(dian)柜、并網逆變器、交流配(pei)(pei)電(dian)(dian)(dian)柜等設備，另外(wai)還(huan)有(you)供電(dian)(dian)(dian)系(xi)統(tong)監控裝置和環境(jing)監測裝置。其運(yun)行(xing)模式是在有(you)太(tai)陽(yang)輻射的條件下，光(guang)伏(fu)發電(dian)(dian)(dian)系(xi)統(tong)的太(tai)陽(yang)能電(dian)(dian)(dian)池組件陣列將太(tai)陽(yang)能轉換(huan)輸(shu)出(chu)的電(dian)(dian)(dian)能，經(jing)過直流匯流箱(xiang)(xiang)集中送入(ru)直流配(pei)(pei)電(dian)(dian)(dian)柜，由并網逆變器逆變成交流電(dian)(dian)(dian)供給建筑自(zi)身負載(zai)，多余或不(bu)足的電(dian)(dian)(dian)力通過聯接(jie)電(dian)(dian)(dian)網來調節。
