山東省青州(zhou)市魯東機(ji)械2.1MW光(guang)伏(fu)發(fa)電(dian)站(zhan)項(xiang)目。彩鋼瓦屋頂光(guang)伏(fu)發(fa)電(dian)站(zhan)，已并網發(fa)電(dian)成功(gong)！

輸送方式

太(tai)陽能光(guang)伏(fu)(fu)發(fa)電分為獨立(li)光(guang)伏(fu)(fu)發(fa)電、并網光(guang)伏(fu)(fu)發(fa)電、分布式光(guang)伏(fu)(fu)發(fa)電

獨立光伏發電

獨立光伏(fu)發電系統也叫離網光伏(fu)發電系統。主要由太陽能電池組件、控制器(qi)、蓄(xu)電池組成，若要為交流負載供電，還(huan)需(xu)要配置交流逆變器(qi)。

并網光伏發電

并網(wang)(wang)光(guang)伏(fu)發(fa)(fa)電(dian)(dian)(dian)系(xi)統就是太陽能組件產生的(de)直(zhi)流(liu)電(dian)(dian)(dian)經過并網(wang)(wang)逆變器轉換(huan)成符合市(shi)電(dian)(dian)(dian)電(dian)(dian)(dian)網(wang)(wang)要求(qiu)的(de)交(jiao)流(liu)電(dian)(dian)(dian)之后直(zhi)接接入公共電(dian)(dian)(dian)網(wang)(wang)。并網(wang)(wang)光(guang)伏(fu)發(fa)(fa)電(dian)(dian)(dian)系(xi)統有集中式(shi)(shi)大型并網(wang)(wang)光(guang)伏(fu)電(dian)(dian)(dian)站一般都是國家(jia)級電(dian)(dian)(dian)站，主要特點是將(jiang)所發(fa)(fa)電(dian)(dian)(dian)能直(zhi)接輸送到電(dian)(dian)(dian)網(wang)(wang)，由電(dian)(dian)(dian)網(wang)(wang)統一調配向用戶供電(dian)(dian)(dian)。但這種電(dian)(dian)(dian)站投資大、建設周(zhou)期長、占(zhan)地(di)面積大，發(fa)(fa)展難(nan)度(du)相對較大。而分(fen)散式(shi)(shi)小(xiao)型并網(wang)(wang)光(guang)伏(fu)系(xi)統，特別是光(guang)伏(fu)建筑一體(ti)化(hua)發(fa)(fa)電(dian)(dian)(dian)系(xi)統，由于(yu)投資小(xiao)、建設快、占(zhan)地(di)面積小(xiao)、政策支持力(li)度(du)大等優(you)點，是并網(wang)(wang)光(guang)伏(fu)發(fa)(fa)電(dian)(dian)(dian)的(de)主流(liu)。

分布式光伏發電

分(fen)布式光(guang)伏發(fa)電系統，又(you)稱分(fen)散式發(fa)電或(huo)分(fen)布式供能，是(shi)指在用(yong)戶現(xian)(xian)場(chang)或(huo)靠近用(yong)電現(xian)(xian)場(chang)配置較(jiao)小的光(guang)伏發(fa)電供電系統，以滿(man)足特定用(yong)戶的需求，支(zhi)持(chi)現(xian)(xian)存配電網(wang)的經濟運行，或(huo)者同(tong)時(shi)滿(man)足這兩(liang)個方面的要求。

　　分布式(shi)(shi)光(guang)伏發電(dian)(dian)(dian)(dian)系(xi)統的(de)基本(ben)設備包括光(guang)伏電(dian)(dian)(dian)(dian)池組(zu)件、光(guang)伏方陣支架、直(zhi)流(liu)匯流(liu)箱(xiang)、直(zhi)流(liu)配(pei)電(dian)(dian)(dian)(dian)柜(ju)(ju)、并網(wang)(wang)逆(ni)變器、交流(liu)配(pei)電(dian)(dian)(dian)(dian)柜(ju)(ju)等(deng)設備，另外還有供電(dian)(dian)(dian)(dian)系(xi)統監(jian)控裝置和(he)環境(jing)監(jian)測裝置。其運行模式(shi)(shi)是在有太(tai)(tai)陽輻射的(de)條件下，光(guang)伏發電(dian)(dian)(dian)(dian)系(xi)統的(de)太(tai)(tai)陽能電(dian)(dian)(dian)(dian)池組(zu)件陣列將太(tai)(tai)陽能轉(zhuan)換(huan)輸出的(de)電(dian)(dian)(dian)(dian)能，經過直(zhi)流(liu)匯流(liu)箱(xiang)集中(zhong)送入直(zhi)流(liu)配(pei)電(dian)(dian)(dian)(dian)柜(ju)(ju)，由并網(wang)(wang)逆(ni)變器逆(ni)變成(cheng)交流(liu)電(dian)(dian)(dian)(dian)供給建筑(zhu)自(zi)身(shen)負載，多余(yu)或不足的(de)電(dian)(dian)(dian)(dian)力通(tong)過聯接電(dian)(dian)(dian)(dian)網(wang)(wang)來調節。
