山(shan)東省青州市(shi)魯(lu)東機(ji)械2.1MW光(guang)伏發電(dian)站(zhan)(zhan)項目。彩鋼瓦屋頂光(guang)伏發電(dian)站(zhan)(zhan)，已(yi)并網發電(dian)成功(gong)！

輸送方式

太陽能(neng)光伏(fu)發(fa)電分為獨(du)立光伏(fu)發(fa)電、并網(wang)光伏(fu)發(fa)電、分布式(shi)光伏(fu)發(fa)電

獨立光伏發電

獨立(li)光伏發電(dian)(dian)系統也叫離網光伏發電(dian)(dian)系統。主要(yao)由太(tai)陽能電(dian)(dian)池(chi)組件、控制器、蓄電(dian)(dian)池(chi)組成，若要(yao)為(wei)交流負載(zai)供電(dian)(dian)，還(huan)需要(yao)配置交流逆變器。

并網光伏發電

并網(wang)光伏(fu)發電(dian)(dian)系(xi)統(tong)就是(shi)太陽能(neng)組件產生的直流(liu)電(dian)(dian)經過并網(wang)逆變器轉換成(cheng)符合市電(dian)(dian)電(dian)(dian)網(wang)要求的交(jiao)流(liu)電(dian)(dian)之后直接接入公共電(dian)(dian)網(wang)。并網(wang)光伏(fu)發電(dian)(dian)系(xi)統(tong)有集(ji)中(zhong)式大型(xing)并網(wang)光伏(fu)電(dian)(dian)站一般都(dou)是(shi)國家級電(dian)(dian)站，主要特點是(shi)將(jiang)所發電(dian)(dian)能(neng)直接輸送到電(dian)(dian)網(wang)，由電(dian)(dian)網(wang)統(tong)一調配(pei)向用戶供電(dian)(dian)。但這(zhe)種電(dian)(dian)站投資(zi)大、建設周期(qi)長、占地面積大，發展難(nan)度相(xiang)對較大。而分(fen)散式小型(xing)并網(wang)光伏(fu)系(xi)統(tong)，特別是(shi)光伏(fu)建筑一體(ti)化發電(dian)(dian)系(xi)統(tong)，由于(yu)投資(zi)小、建設快、占地面積小、政策支持力度大等優點，是(shi)并網(wang)光伏(fu)發電(dian)(dian)的主流(liu)。

分布式光伏發電

分布(bu)式光伏發電(dian)系(xi)(xi)統，又稱分散式發電(dian)或(huo)(huo)分布(bu)式供能，是指在用(yong)(yong)戶現場(chang)或(huo)(huo)靠(kao)近(jin)用(yong)(yong)電(dian)現場(chang)配置較小的(de)(de)(de)光伏發電(dian)供電(dian)系(xi)(xi)統，以滿(man)足特定用(yong)(yong)戶的(de)(de)(de)需(xu)求(qiu)，支持(chi)現存配電(dian)網的(de)(de)(de)經(jing)濟(ji)運行，或(huo)(huo)者同時滿(man)足這兩個方面的(de)(de)(de)要求(qiu)。

　　分布(bu)式(shi)光伏(fu)發電(dian)(dian)(dian)系統的基本設備(bei)包括光伏(fu)電(dian)(dian)(dian)池組(zu)件、光伏(fu)方陣支架、直(zhi)(zhi)流(liu)(liu)匯(hui)流(liu)(liu)箱(xiang)、直(zhi)(zhi)流(liu)(liu)配電(dian)(dian)(dian)柜(ju)、并網逆(ni)變(bian)(bian)器、交(jiao)流(liu)(liu)配電(dian)(dian)(dian)柜(ju)等設備(bei)，另外還有供(gong)電(dian)(dian)(dian)系統監(jian)控(kong)裝置(zhi)和環境監(jian)測裝置(zhi)。其運行模式(shi)是在有太(tai)陽(yang)輻(fu)射的條(tiao)件下，光伏(fu)發電(dian)(dian)(dian)系統的太(tai)陽(yang)能電(dian)(dian)(dian)池組(zu)件陣列(lie)將太(tai)陽(yang)能轉換(huan)輸(shu)出(chu)的電(dian)(dian)(dian)能，經過(guo)直(zhi)(zhi)流(liu)(liu)匯(hui)流(liu)(liu)箱(xiang)集中送(song)入直(zhi)(zhi)流(liu)(liu)配電(dian)(dian)(dian)柜(ju)，由(you)并網逆(ni)變(bian)(bian)器逆(ni)變(bian)(bian)成交(jiao)流(liu)(liu)電(dian)(dian)(dian)供(gong)給建筑(zhu)自身負(fu)載，多余或(huo)不足(zu)的電(dian)(dian)(dian)力通過(guo)聯接電(dian)(dian)(dian)網來調節。
