山東省青州市魯(lu)東機械2.1MW光伏發電站(zhan)項目。彩鋼瓦屋頂光伏發電站(zhan)，已并網發電成功！

輸送方式

太陽(yang)能(neng)光伏(fu)發(fa)電(dian)分(fen)為獨(du)立光伏(fu)發(fa)電(dian)、并網(wang)光伏(fu)發(fa)電(dian)、分(fen)布式光伏(fu)發(fa)電(dian)

獨立光伏發電

獨立光伏發電(dian)系統也叫離網光伏發電(dian)系統。主要(yao)由太(tai)陽(yang)能(neng)電(dian)池組件(jian)、控制器(qi)、蓄電(dian)池組成，若要(yao)為交流負載供(gong)電(dian)，還(huan)需要(yao)配置交流逆變器(qi)。

并網光伏發電

并網(wang)(wang)(wang)光(guang)伏(fu)發(fa)(fa)電(dian)(dian)系(xi)統(tong)就是(shi)(shi)太(tai)陽能(neng)組件產生的直(zhi)(zhi)流(liu)電(dian)(dian)經過并網(wang)(wang)(wang)逆變器轉換(huan)成符合市電(dian)(dian)電(dian)(dian)網(wang)(wang)(wang)要求的交流(liu)電(dian)(dian)之后直(zhi)(zhi)接接入(ru)公(gong)共(gong)電(dian)(dian)網(wang)(wang)(wang)。并網(wang)(wang)(wang)光(guang)伏(fu)發(fa)(fa)電(dian)(dian)系(xi)統(tong)有集中式(shi)大型(xing)并網(wang)(wang)(wang)光(guang)伏(fu)電(dian)(dian)站(zhan)(zhan)(zhan)一般都(dou)是(shi)(shi)國家(jia)級(ji)電(dian)(dian)站(zhan)(zhan)(zhan)，主(zhu)要特點(dian)(dian)是(shi)(shi)將所(suo)發(fa)(fa)電(dian)(dian)能(neng)直(zhi)(zhi)接輸送到電(dian)(dian)網(wang)(wang)(wang)，由(you)(you)電(dian)(dian)網(wang)(wang)(wang)統(tong)一調配向用戶供(gong)電(dian)(dian)。但這(zhe)種電(dian)(dian)站(zhan)(zhan)(zhan)投資大、建(jian)設周期長、占(zhan)地(di)面積大，發(fa)(fa)展難(nan)度相對較(jiao)大。而分散式(shi)小型(xing)并網(wang)(wang)(wang)光(guang)伏(fu)系(xi)統(tong)，特別(bie)是(shi)(shi)光(guang)伏(fu)建(jian)筑一體化發(fa)(fa)電(dian)(dian)系(xi)統(tong)，由(you)(you)于投資小、建(jian)設快、占(zhan)地(di)面積小、政策支持力(li)度大等優點(dian)(dian)，是(shi)(shi)并網(wang)(wang)(wang)光(guang)伏(fu)發(fa)(fa)電(dian)(dian)的主(zhu)流(liu)。

分布式光伏發電

分布式(shi)光伏發(fa)電(dian)(dian)(dian)系統，又稱(cheng)分散式(shi)發(fa)電(dian)(dian)(dian)或分布式(shi)供能，是指(zhi)在用(yong)戶現(xian)場或靠近用(yong)電(dian)(dian)(dian)現(xian)場配置較小的光伏發(fa)電(dian)(dian)(dian)供電(dian)(dian)(dian)系統，以(yi)滿(man)足特(te)定(ding)用(yong)戶的需求，支(zhi)持現(xian)存配電(dian)(dian)(dian)網(wang)的經濟運行，或者(zhe)同時滿(man)足這兩個方面(mian)的要求。

　　分布式光伏發(fa)電(dian)(dian)系(xi)統的(de)基(ji)本設(she)備包括光伏電(dian)(dian)池組(zu)件(jian)、光伏方陣支(zhi)架、直流(liu)匯流(liu)箱、直流(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(she)備，另外還有(you)供電(dian)(dian)系(xi)統監控(kong)裝置和(he)環境監測裝置。其運行模式是在有(you)太(tai)陽輻(fu)射的(de)條件(jian)下(xia)，光伏發(fa)電(dian)(dian)系(xi)統的(de)太(tai)陽能(neng)電(dian)(dian)池組(zu)件(jian)陣列將太(tai)陽能(neng)轉換(huan)輸(shu)出的(de)電(dian)(dian)能(neng)，經過(guo)直流(liu)匯流(liu)箱集中送入直流(liu)配(pei)電(dian)(dian)柜，由并(bing)網逆(ni)變器逆(ni)變成(cheng)交流(liu)電(dian)(dian)供給建筑自身負(fu)載(zai)，多余或不足的(de)電(dian)(dian)力通過(guo)聯接電(dian)(dian)網來調節(jie)。
