山東省青州(zhou)市魯東機械2.1MW光伏發電(dian)站項目(mu)。彩鋼瓦(wa)屋頂光伏發電(dian)站，已并網發電(dian)成(cheng)功(gong)！

輸送方式

太陽能光(guang)伏(fu)發(fa)電分(fen)(fen)為獨立光(guang)伏(fu)發(fa)電、并網光(guang)伏(fu)發(fa)電、分(fen)(fen)布式光(guang)伏(fu)發(fa)電

獨立光伏發電

獨立光伏發電系統也叫離網光伏發電系統。主要由太(tai)陽能(neng)電池組件(jian)、控制器、蓄電池組成，若要為交流負載供電，還需要配置交流逆變器。

并網光伏發電

并(bing)網(wang)(wang)光(guang)(guang)伏(fu)(fu)(fu)(fu)發(fa)電(dian)(dian)(dian)系統就是(shi)太陽能組件(jian)產生的(de)直(zhi)流(liu)電(dian)(dian)(dian)經過并(bing)網(wang)(wang)逆變器(qi)轉換成符合市電(dian)(dian)(dian)電(dian)(dian)(dian)網(wang)(wang)要求的(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(bing)網(wang)(wang)光(guang)(guang)伏(fu)(fu)(fu)(fu)發(fa)電(dian)(dian)(dian)系統有集中式大型并(bing)網(wang)(wang)光(guang)(guang)伏(fu)(fu)(fu)(fu)電(dian)(dian)(dian)站一(yi)(yi)(yi)般都(dou)是(shi)國家級電(dian)(dian)(dian)站，主要特點是(shi)將所(suo)發(fa)電(dian)(dian)(dian)能直(zhi)接輸送到電(dian)(dian)(dian)網(wang)(wang)，由(you)電(dian)(dian)(dian)網(wang)(wang)統一(yi)(yi)(yi)調配向用戶供(gong)電(dian)(dian)(dian)。但這種電(dian)(dian)(dian)站投資大、建(jian)設周期(qi)長、占地面積大，發(fa)展難度相(xiang)對(dui)較大。而分散(san)式小(xiao)型并(bing)網(wang)(wang)光(guang)(guang)伏(fu)(fu)(fu)(fu)系統，特別是(shi)光(guang)(guang)伏(fu)(fu)(fu)(fu)建(jian)筑一(yi)(yi)(yi)體化發(fa)電(dian)(dian)(dian)系統，由(you)于投資小(xiao)、建(jian)設快(kuai)、占地面積小(xiao)、政策支持力度大等優點，是(shi)并(bing)網(wang)(wang)光(guang)(guang)伏(fu)(fu)(fu)(fu)發(fa)電(dian)(dian)(dian)的(de)主流(liu)。

分布式光伏發電

分(fen)布式(shi)光伏發(fa)(fa)電(dian)系統，又稱分(fen)散式(shi)發(fa)(fa)電(dian)或分(fen)布式(shi)供能，是指在用戶(hu)現(xian)場或靠近用電(dian)現(xian)場配置較小(xiao)的(de)光伏發(fa)(fa)電(dian)供電(dian)系統，以滿(man)足(zu)特定用戶(hu)的(de)需求(qiu)，支持現(xian)存配電(dian)網的(de)經濟運行，或者同(tong)時滿(man)足(zu)這兩個方(fang)面(mian)的(de)要求(qiu)。

　　分(fen)布式光(guang)(guang)伏(fu)發(fa)電(dian)(dian)(dian)系統的(de)基本設(she)備(bei)(bei)包括光(guang)(guang)伏(fu)電(dian)(dian)(dian)池組(zu)件、光(guang)(guang)伏(fu)方陣支(zhi)架、直(zhi)(zhi)流(liu)匯流(liu)箱、直(zhi)(zhi)流(liu)配電(dian)(dian)(dian)柜、并(bing)網(wang)逆變(bian)(bian)器、交(jiao)流(liu)配電(dian)(dian)(dian)柜等設(she)備(bei)(bei)，另外還有供電(dian)(dian)(dian)系統監控裝(zhuang)置和環境監測裝(zhuang)置。其運(yun)行模式是在有太(tai)陽輻(fu)射的(de)條件下，光(guang)(guang)伏(fu)發(fa)電(dian)(dian)(dian)系統的(de)太(tai)陽能(neng)電(dian)(dian)(dian)池組(zu)件陣列將太(tai)陽能(neng)轉換輸出的(de)電(dian)(dian)(dian)能(neng)，經過直(zhi)(zhi)流(liu)匯流(liu)箱集中送(song)入直(zhi)(zhi)流(liu)配電(dian)(dian)(dian)柜，由并(bing)網(wang)逆變(bian)(bian)器逆變(bian)(bian)成交(jiao)流(liu)電(dian)(dian)(dian)供給建筑自身負載，多余或不足的(de)電(dian)(dian)(dian)力通過聯接電(dian)(dian)(dian)網(wang)來調節。
