山(shan)東省青州市魯東機械(xie)2.1MW光伏發(fa)電(dian)(dian)站項目。彩鋼瓦屋頂光伏發(fa)電(dian)(dian)站，已(yi)并網(wang)發(fa)電(dian)(dian)成功(gong)！

輸送方式

太陽能光(guang)(guang)伏發(fa)電(dian)分為獨立光(guang)(guang)伏發(fa)電(dian)、并網光(guang)(guang)伏發(fa)電(dian)、分布(bu)式光(guang)(guang)伏發(fa)電(dian)

獨立光伏發電

獨立光伏(fu)發(fa)電系統也叫離(li)網光伏(fu)發(fa)電系統。主要由太(tai)陽能電池組(zu)(zu)件、控制器、蓄(xu)電池組(zu)(zu)成，若(ruo)要為(wei)交流(liu)負載(zai)供電，還需要配置交流(liu)逆變器。

并網光伏發電

并網(wang)(wang)光(guang)(guang)伏(fu)(fu)發(fa)電(dian)(dian)系(xi)統就是(shi)(shi)(shi)太陽能(neng)組件產生的(de)直(zhi)流電(dian)(dian)經(jing)過并網(wang)(wang)逆變器轉(zhuan)換成符合市電(dian)(dian)電(dian)(dian)網(wang)(wang)要(yao)求的(de)交流電(dian)(dian)之后直(zhi)接接入公共(gong)電(dian)(dian)網(wang)(wang)。并網(wang)(wang)光(guang)(guang)伏(fu)(fu)發(fa)電(dian)(dian)系(xi)統有集中式大(da)(da)型(xing)并網(wang)(wang)光(guang)(guang)伏(fu)(fu)電(dian)(dian)站(zhan)一(yi)般都是(shi)(shi)(shi)國家級電(dian)(dian)站(zhan)，主要(yao)特點是(shi)(shi)(shi)將所發(fa)電(dian)(dian)能(neng)直(zhi)接輸(shu)送到(dao)電(dian)(dian)網(wang)(wang)，由電(dian)(dian)網(wang)(wang)統一(yi)調配向用戶供電(dian)(dian)。但這(zhe)種(zhong)電(dian)(dian)站(zhan)投資(zi)大(da)(da)、建設周(zhou)期長、占(zhan)(zhan)地(di)面積(ji)大(da)(da)，發(fa)展難度(du)相對(dui)較大(da)(da)。而(er)分散式小型(xing)并網(wang)(wang)光(guang)(guang)伏(fu)(fu)系(xi)統，特別是(shi)(shi)(shi)光(guang)(guang)伏(fu)(fu)建筑一(yi)體(ti)化發(fa)電(dian)(dian)系(xi)統，由于投資(zi)小、建設快、占(zhan)(zhan)地(di)面積(ji)小、政策支持力度(du)大(da)(da)等優點，是(shi)(shi)(shi)并網(wang)(wang)光(guang)(guang)伏(fu)(fu)發(fa)電(dian)(dian)的(de)主流。

分布式光伏發電

分(fen)布式光(guang)伏發電(dian)系統，又稱分(fen)散式發電(dian)或(huo)(huo)分(fen)布式供(gong)能，是指在用戶(hu)現場(chang)或(huo)(huo)靠近用電(dian)現場(chang)配置(zhi)較小(xiao)的光(guang)伏發電(dian)供(gong)電(dian)系統，以滿(man)足特定用戶(hu)的需求，支持現存配電(dian)網的經(jing)濟運行(xing)，或(huo)(huo)者同時滿(man)足這兩個方面(mian)的要求。

　　分布式(shi)光伏(fu)發電(dian)(dian)(dian)(dian)系統(tong)的(de)基(ji)本設備包括(kuo)光伏(fu)電(dian)(dian)(dian)(dian)池組件、光伏(fu)方陣支架(jia)、直流(liu)匯流(liu)箱(xiang)(xiang)、直流(liu)配電(dian)(dian)(dian)(dian)柜(ju)、并網(wang)(wang)逆變(bian)器、交流(liu)配電(dian)(dian)(dian)(dian)柜(ju)等設備，另外還有(you)供電(dian)(dian)(dian)(dian)系統(tong)監(jian)控(kong)裝置(zhi)和環境監(jian)測裝置(zhi)。其(qi)運行模式(shi)是在有(you)太(tai)(tai)陽輻射的(de)條件下(xia)，光伏(fu)發電(dian)(dian)(dian)(dian)系統(tong)的(de)太(tai)(tai)陽能電(dian)(dian)(dian)(dian)池組件陣列(lie)將(jiang)太(tai)(tai)陽能轉換輸出的(de)電(dian)(dian)(dian)(dian)能，經(jing)過直流(liu)匯流(liu)箱(xiang)(xiang)集中送入(ru)直流(liu)配電(dian)(dian)(dian)(dian)柜(ju)，由并網(wang)(wang)逆變(bian)器逆變(bian)成交流(liu)電(dian)(dian)(dian)(dian)供給建筑自身負載(zai)，多余(yu)或不足的(de)電(dian)(dian)(dian)(dian)力通(tong)過聯接電(dian)(dian)(dian)(dian)網(wang)(wang)來調節。
