山東省青州市魯東機械2.1MW光伏發(fa)電站項(xiang)目。彩鋼(gang)瓦(wa)屋頂光伏發(fa)電站，已并網發(fa)電成功！

輸送方式

太陽能(neng)光(guang)伏(fu)(fu)發(fa)(fa)電分為獨(du)立光(guang)伏(fu)(fu)發(fa)(fa)電、并網光(guang)伏(fu)(fu)發(fa)(fa)電、分布式光(guang)伏(fu)(fu)發(fa)(fa)電

獨立光伏發電

獨立光伏(fu)發電(dian)系(xi)統也叫離網光伏(fu)發電(dian)系(xi)統。主要由太(tai)陽能電(dian)池(chi)(chi)組(zu)件、控制(zhi)器、蓄電(dian)池(chi)(chi)組(zu)成，若要為交流(liu)(liu)負載(zai)供電(dian)，還(huan)需要配置交流(liu)(liu)逆變器。

并網光伏發電

并網(wang)(wang)(wang)(wang)光(guang)(guang)(guang)伏(fu)發(fa)電(dian)(dian)(dian)(dian)(dian)系(xi)統就是(shi)太(tai)陽能(neng)(neng)組件產生(sheng)的(de)直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)經過并網(wang)(wang)(wang)(wang)逆變器轉換成符合市電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)要求的(de)交流(liu)電(dian)(dian)(dian)(dian)(dian)之后直(zhi)接(jie)(jie)接(jie)(jie)入公共電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)。并網(wang)(wang)(wang)(wang)光(guang)(guang)(guang)伏(fu)發(fa)電(dian)(dian)(dian)(dian)(dian)系(xi)統有集中式大(da)型并網(wang)(wang)(wang)(wang)光(guang)(guang)(guang)伏(fu)電(dian)(dian)(dian)(dian)(dian)站一般(ban)都是(shi)國家(jia)級電(dian)(dian)(dian)(dian)(dian)站，主要特(te)點是(shi)將所發(fa)電(dian)(dian)(dian)(dian)(dian)能(neng)(neng)直(zhi)接(jie)(jie)輸送到電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)，由(you)電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)統一調配(pei)向用戶(hu)供電(dian)(dian)(dian)(dian)(dian)。但這種電(dian)(dian)(dian)(dian)(dian)站投資大(da)、建(jian)(jian)設周期長、占地面(mian)積大(da)，發(fa)展難(nan)度相對較大(da)。而(er)分散(san)式小(xiao)型并網(wang)(wang)(wang)(wang)光(guang)(guang)(guang)伏(fu)系(xi)統，特(te)別是(shi)光(guang)(guang)(guang)伏(fu)建(jian)(jian)筑一體化發(fa)電(dian)(dian)(dian)(dian)(dian)系(xi)統，由(you)于(yu)投資小(xiao)、建(jian)(jian)設快、占地面(mian)積小(xiao)、政策支(zhi)持力度大(da)等優點，是(shi)并網(wang)(wang)(wang)(wang)光(guang)(guang)(guang)伏(fu)發(fa)電(dian)(dian)(dian)(dian)(dian)的(de)主流(liu)。

分布式光伏發電

分(fen)(fen)布(bu)式光(guang)伏發電系統，又稱分(fen)(fen)散式發電或(huo)分(fen)(fen)布(bu)式供能，是指在用(yong)戶(hu)現(xian)場或(huo)靠(kao)近用(yong)電現(xian)場配置(zhi)較(jiao)小(xiao)的(de)(de)光(guang)伏發電供電系統，以滿足特定用(yong)戶(hu)的(de)(de)需求，支持現(xian)存配電網的(de)(de)經濟運行，或(huo)者同時滿足這兩個方面的(de)(de)要求。

　　分布式光(guang)(guang)伏(fu)發電(dian)(dian)系(xi)(xi)統的(de)基本設(she)備(bei)包括光(guang)(guang)伏(fu)電(dian)(dian)池組件(jian)、光(guang)(guang)伏(fu)方(fang)陣支架、直(zhi)流(liu)匯流(liu)箱、直(zhi)流(liu)配電(dian)(dian)柜(ju)、并網(wang)逆變器(qi)、交(jiao)流(liu)配電(dian)(dian)柜(ju)等設(she)備(bei)，另外還有(you)供電(dian)(dian)系(xi)(xi)統監控裝置和環境監測裝置。其運行模式是在有(you)太(tai)陽(yang)(yang)輻射的(de)條件(jian)下(xia)，光(guang)(guang)伏(fu)發電(dian)(dian)系(xi)(xi)統的(de)太(tai)陽(yang)(yang)能電(dian)(dian)池組件(jian)陣列將太(tai)陽(yang)(yang)能轉換輸(shu)出(chu)的(de)電(dian)(dian)能，經(jing)過直(zhi)流(liu)匯流(liu)箱集中送入(ru)直(zhi)流(liu)配電(dian)(dian)柜(ju)，由并網(wang)逆變器(qi)逆變成交(jiao)流(liu)電(dian)(dian)供給建筑自身(shen)負載，多(duo)余或不足的(de)電(dian)(dian)力通過聯接(jie)電(dian)(dian)網(wang)來調節。
