山(shan)東省青州市(shi)魯東機械(xie)2.1MW光伏(fu)發(fa)電站(zhan)項(xiang)目。彩鋼瓦屋頂光伏(fu)發(fa)電站(zhan)，已并網發(fa)電成功！

輸送方式

太(tai)陽能光伏發(fa)(fa)(fa)電(dian)分(fen)為(wei)獨立(li)光伏發(fa)(fa)(fa)電(dian)、并(bing)網光伏發(fa)(fa)(fa)電(dian)、分(fen)布式光伏發(fa)(fa)(fa)電(dian)

獨立光伏發電

獨(du)立(li)光伏發電系統(tong)也叫(jiao)離網光伏發電系統(tong)。主要(yao)(yao)由太(tai)陽能電池組件、控(kong)制器、蓄電池組成，若要(yao)(yao)為交流(liu)負(fu)載供電，還需(xu)要(yao)(yao)配置交流(liu)逆變(bian)器。

并網光伏發電

并網光(guang)(guang)伏(fu)(fu)發(fa)(fa)電(dian)系(xi)統(tong)就是(shi)(shi)太陽能組件產(chan)生的(de)直(zhi)流電(dian)經過并網逆(ni)變器(qi)轉換成(cheng)符合市電(dian)電(dian)網要求的(de)交流電(dian)之(zhi)后直(zhi)接接入公共(gong)電(dian)網。并網光(guang)(guang)伏(fu)(fu)發(fa)(fa)電(dian)系(xi)統(tong)有集(ji)中(zhong)式大(da)型并網光(guang)(guang)伏(fu)(fu)電(dian)站(zhan)一(yi)般都是(shi)(shi)國家級電(dian)站(zhan)，主(zhu)(zhu)要特(te)點是(shi)(shi)將所發(fa)(fa)電(dian)能直(zhi)接輸(shu)送到(dao)電(dian)網，由電(dian)網統(tong)一(yi)調配向用戶供電(dian)。但這種電(dian)站(zhan)投資大(da)、建設周期長(chang)、占地面積(ji)大(da)，發(fa)(fa)展(zhan)難度相對較大(da)。而分散式小(xiao)型并網光(guang)(guang)伏(fu)(fu)系(xi)統(tong)，特(te)別是(shi)(shi)光(guang)(guang)伏(fu)(fu)建筑一(yi)體化發(fa)(fa)電(dian)系(xi)統(tong)，由于投資小(xiao)、建設快、占地面積(ji)小(xiao)、政策(ce)支持力度大(da)等優點，是(shi)(shi)并網光(guang)(guang)伏(fu)(fu)發(fa)(fa)電(dian)的(de)主(zhu)(zhu)流。

分布式光伏發電

分布(bu)式(shi)(shi)光伏發(fa)電(dian)(dian)系(xi)統，又稱分散式(shi)(shi)發(fa)電(dian)(dian)或分布(bu)式(shi)(shi)供能，是指在用(yong)(yong)戶(hu)現場(chang)或靠近用(yong)(yong)電(dian)(dian)現場(chang)配(pei)置較小的(de)光伏發(fa)電(dian)(dian)供電(dian)(dian)系(xi)統，以滿足(zu)特定用(yong)(yong)戶(hu)的(de)需求，支(zhi)持現存配(pei)電(dian)(dian)網的(de)經濟運行，或者同時滿足(zu)這兩個方面的(de)要求。

　　分(fen)布式光(guang)伏(fu)發電(dian)(dian)(dian)系統(tong)的基本設(she)備(bei)包括光(guang)伏(fu)電(dian)(dian)(dian)池(chi)組(zu)件(jian)、光(guang)伏(fu)方陣支(zhi)架、直(zhi)(zhi)流(liu)(liu)匯流(liu)(liu)箱(xiang)、直(zhi)(zhi)流(liu)(liu)配(pei)電(dian)(dian)(dian)柜(ju)、并網(wang)逆(ni)(ni)變(bian)器(qi)、交流(liu)(liu)配(pei)電(dian)(dian)(dian)柜(ju)等設(she)備(bei)，另外還(huan)有(you)供電(dian)(dian)(dian)系統(tong)監控(kong)裝置(zhi)和環境監測裝置(zhi)。其(qi)運行(xing)模式是(shi)在有(you)太(tai)陽輻(fu)射的條件(jian)下，光(guang)伏(fu)發電(dian)(dian)(dian)系統(tong)的太(tai)陽能電(dian)(dian)(dian)池(chi)組(zu)件(jian)陣列將太(tai)陽能轉換(huan)輸出(chu)的電(dian)(dian)(dian)能，經過直(zhi)(zhi)流(liu)(liu)匯流(liu)(liu)箱(xiang)集中送(song)入直(zhi)(zhi)流(liu)(liu)配(pei)電(dian)(dian)(dian)柜(ju)，由并網(wang)逆(ni)(ni)變(bian)器(qi)逆(ni)(ni)變(bian)成交流(liu)(liu)電(dian)(dian)(dian)供給建筑自身負載，多余(yu)或(huo)不足的電(dian)(dian)(dian)力通過聯接電(dian)(dian)(dian)網(wang)來調節。
