山(shan)東省(sheng)青(qing)州(zhou)市魯東機(ji)械2.1MW光伏(fu)發電站(zhan)項目(mu)。彩鋼(gang)瓦(wa)屋頂光伏(fu)發電站(zhan)，已(yi)并網發電成功！

輸送方式

太陽(yang)能光(guang)伏(fu)(fu)發(fa)電(dian)分(fen)為獨立光(guang)伏(fu)(fu)發(fa)電(dian)、并網光(guang)伏(fu)(fu)發(fa)電(dian)、分(fen)布(bu)式(shi)光(guang)伏(fu)(fu)發(fa)電(dian)

獨立光伏發電

獨立光(guang)伏發(fa)電(dian)系統也叫離網光(guang)伏發(fa)電(dian)系統。主要由太陽(yang)能電(dian)池(chi)組件、控制(zhi)器(qi)、蓄電(dian)池(chi)組成(cheng)，若要為交流負載供電(dian)，還需要配置交流逆變器(qi)。

并網光伏發電

分布式光伏發電

分布(bu)式光(guang)伏發電(dian)系(xi)統(tong)，又稱分散式發電(dian)或分布(bu)式供能，是指在用戶現場(chang)或靠近用電(dian)現場(chang)配置較小的(de)光(guang)伏發電(dian)供電(dian)系(xi)統(tong)，以滿足(zu)(zu)特定用戶的(de)需求，支持現存配電(dian)網的(de)經濟運行，或者(zhe)同時滿足(zu)(zu)這兩個(ge)方面(mian)的(de)要求。

　　分布式(shi)光(guang)伏發(fa)電(dian)(dian)系(xi)統的基本設備(bei)包括光(guang)伏電(dian)(dian)池(chi)組(zu)件(jian)、光(guang)伏方陣支架、直(zhi)流匯(hui)(hui)流箱、直(zhi)流配電(dian)(dian)柜、并網(wang)逆(ni)變(bian)器、交(jiao)(jiao)流配電(dian)(dian)柜等設備(bei)，另外還有供電(dian)(dian)系(xi)統監控裝(zhuang)置和(he)環境(jing)監測裝(zhuang)置。其運(yun)行模式(shi)是在有太陽輻射的條件(jian)下，光(guang)伏發(fa)電(dian)(dian)系(xi)統的太陽能(neng)電(dian)(dian)池(chi)組(zu)件(jian)陣列(lie)將太陽能(neng)轉換輸出的電(dian)(dian)能(neng)，經(jing)過(guo)直(zhi)流匯(hui)(hui)流箱集中送(song)入直(zhi)流配電(dian)(dian)柜，由并網(wang)逆(ni)變(bian)器逆(ni)變(bian)成交(jiao)(jiao)流電(dian)(dian)供給建筑自身負(fu)載，多余或不足的電(dian)(dian)力通(tong)過(guo)聯接電(dian)(dian)網(wang)來調節。
