山東省青州市魯東機械(xie)2.1MW光(guang)伏(fu)發(fa)電站(zhan)項目。彩鋼(gang)瓦屋(wu)頂光(guang)伏(fu)發(fa)電站(zhan)，已(yi)并網(wang)發(fa)電成功！

輸送方式

太陽能光伏(fu)發(fa)電分(fen)(fen)為獨(du)立光伏(fu)發(fa)電、并網(wang)光伏(fu)發(fa)電、分(fen)(fen)布式光伏(fu)發(fa)電

獨立光伏發電

獨立光(guang)(guang)伏發電(dian)系(xi)統也叫離網光(guang)(guang)伏發電(dian)系(xi)統。主要(yao)由太(tai)陽能電(dian)池(chi)組(zu)件、控制器、蓄電(dian)池(chi)組(zu)成，若要(yao)為交流負載供電(dian)，還需要(yao)配(pei)置交流逆(ni)變器。

并網光伏發電

并(bing)網(wang)(wang)光伏(fu)發電(dian)(dian)(dian)(dian)(dian)(dian)系統(tong)就是(shi)(shi)(shi)(shi)太陽能組件(jian)產生的直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)經過并(bing)網(wang)(wang)逆變器轉換成符合市(shi)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)(wang)要求的交流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)之后直接接入公共電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)(wang)。并(bing)網(wang)(wang)光伏(fu)發電(dian)(dian)(dian)(dian)(dian)(dian)系統(tong)有集中(zhong)式(shi)大型并(bing)網(wang)(wang)光伏(fu)電(dian)(dian)(dian)(dian)(dian)(dian)站一般都是(shi)(shi)(shi)(shi)國家(jia)級電(dian)(dian)(dian)(dian)(dian)(dian)站，主(zhu)要特(te)點是(shi)(shi)(shi)(shi)將所發電(dian)(dian)(dian)(dian)(dian)(dian)能直接輸送到電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)(wang)，由電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)(wang)統(tong)一調(diao)配向用戶(hu)供電(dian)(dian)(dian)(dian)(dian)(dian)。但這種電(dian)(dian)(dian)(dian)(dian)(dian)站投(tou)(tou)資大、建(jian)設周期長、占地面積大，發展難度相(xiang)對較大。而分(fen)散式(shi)小(xiao)型并(bing)網(wang)(wang)光伏(fu)系統(tong)，特(te)別是(shi)(shi)(shi)(shi)光伏(fu)建(jian)筑一體化發電(dian)(dian)(dian)(dian)(dian)(dian)系統(tong)，由于投(tou)(tou)資小(xiao)、建(jian)設快、占地面積小(xiao)、政策支持力度大等優點，是(shi)(shi)(shi)(shi)并(bing)網(wang)(wang)光伏(fu)發電(dian)(dian)(dian)(dian)(dian)(dian)的主(zhu)流(liu)。

分布式光伏發電

分(fen)布(bu)式光伏發電(dian)(dian)(dian)(dian)系(xi)統，又稱分(fen)散式發電(dian)(dian)(dian)(dian)或(huo)(huo)分(fen)布(bu)式供(gong)能，是指在(zai)用戶現場或(huo)(huo)靠近用電(dian)(dian)(dian)(dian)現場配(pei)置較小的光伏發電(dian)(dian)(dian)(dian)供(gong)電(dian)(dian)(dian)(dian)系(xi)統，以滿足特(te)定(ding)用戶的需求，支持現存配(pei)電(dian)(dian)(dian)(dian)網的經濟運行，或(huo)(huo)者(zhe)同時滿足這兩個方面(mian)的要(yao)求。

　　分(fen)布式光(guang)伏發電(dian)(dian)系(xi)(xi)統的(de)(de)基本設備包括光(guang)伏電(dian)(dian)池組(zu)件、光(guang)伏方陣支(zhi)架、直流匯(hui)流箱、直流配電(dian)(dian)柜(ju)(ju)、并網逆變(bian)器(qi)、交流配電(dian)(dian)柜(ju)(ju)等設備，另外還有供電(dian)(dian)系(xi)(xi)統監控裝置和環(huan)境監測裝置。其運行模式是在(zai)有太陽(yang)輻射(she)的(de)(de)條件下，光(guang)伏發電(dian)(dian)系(xi)(xi)統的(de)(de)太陽(yang)能電(dian)(dian)池組(zu)件陣列將太陽(yang)能轉換輸出的(de)(de)電(dian)(dian)能，經過(guo)直流匯(hui)流箱集(ji)中送入(ru)直流配電(dian)(dian)柜(ju)(ju)，由并網逆變(bian)器(qi)逆變(bian)成交流電(dian)(dian)供給建筑自身負載，多余或(huo)不足的(de)(de)電(dian)(dian)力通過(guo)聯接(jie)電(dian)(dian)網來調節。
