山(shan)東省青州市魯東機械2.1MW光(guang)伏發電(dian)(dian)站(zhan)(zhan)項目。彩鋼瓦屋頂(ding)光(guang)伏發電(dian)(dian)站(zhan)(zhan)，已并(bing)網發電(dian)(dian)成功(gong)！

輸送方式

太陽能光(guang)伏(fu)(fu)發電(dian)分為獨立光(guang)伏(fu)(fu)發電(dian)、并網光(guang)伏(fu)(fu)發電(dian)、分布式光(guang)伏(fu)(fu)發電(dian)

獨立光伏發電

獨立光伏(fu)發電(dian)系(xi)統也(ye)叫離網(wang)光伏(fu)發電(dian)系(xi)統。主要由太(tai)陽能電(dian)池組件、控(kong)制(zhi)器(qi)、蓄電(dian)池組成(cheng)，若要為交(jiao)流負載供電(dian)，還需要配置交(jiao)流逆(ni)變器(qi)。

并網光伏發電

并網(wang)(wang)光伏(fu)發(fa)電(dian)(dian)(dian)(dian)系(xi)統(tong)(tong)就是(shi)太(tai)陽(yang)能(neng)組件產生的直流(liu)(liu)電(dian)(dian)(dian)(dian)經過并網(wang)(wang)逆變器轉換成符合市(shi)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)網(wang)(wang)要求的交流(liu)(liu)電(dian)(dian)(dian)(dian)之后直接(jie)(jie)(jie)接(jie)(jie)(jie)入公共電(dian)(dian)(dian)(dian)網(wang)(wang)。并網(wang)(wang)光伏(fu)發(fa)電(dian)(dian)(dian)(dian)系(xi)統(tong)(tong)有集中式(shi)大(da)型(xing)并網(wang)(wang)光伏(fu)電(dian)(dian)(dian)(dian)站一(yi)般都是(shi)國家級電(dian)(dian)(dian)(dian)站，主要特點是(shi)將所發(fa)電(dian)(dian)(dian)(dian)能(neng)直接(jie)(jie)(jie)輸送到電(dian)(dian)(dian)(dian)網(wang)(wang)，由電(dian)(dian)(dian)(dian)網(wang)(wang)統(tong)(tong)一(yi)調(diao)配向用(yong)戶供電(dian)(dian)(dian)(dian)。但這種電(dian)(dian)(dian)(dian)站投資大(da)、建設周期長、占地面(mian)積(ji)(ji)大(da)，發(fa)展難度(du)相對較大(da)。而分散式(shi)小(xiao)型(xing)并網(wang)(wang)光伏(fu)系(xi)統(tong)(tong)，特別(bie)是(shi)光伏(fu)建筑一(yi)體化發(fa)電(dian)(dian)(dian)(dian)系(xi)統(tong)(tong)，由于投資小(xiao)、建設快(kuai)、占地面(mian)積(ji)(ji)小(xiao)、政策支持力度(du)大(da)等優點，是(shi)并網(wang)(wang)光伏(fu)發(fa)電(dian)(dian)(dian)(dian)的主流(liu)(liu)。

分布式光伏發電

分布式光伏(fu)發(fa)電(dian)系統，又稱(cheng)分散(san)式發(fa)電(dian)或(huo)分布式供(gong)能(neng)，是(shi)指(zhi)在用(yong)(yong)(yong)戶現場(chang)或(huo)靠近用(yong)(yong)(yong)電(dian)現場(chang)配置(zhi)較(jiao)小的(de)光伏(fu)發(fa)電(dian)供(gong)電(dian)系統，以滿(man)足(zu)特(te)定用(yong)(yong)(yong)戶的(de)需(xu)求，支持(chi)現存配電(dian)網的(de)經濟運(yun)行，或(huo)者同(tong)時滿(man)足(zu)這兩個方面的(de)要(yao)求。

　　分布式(shi)光(guang)伏發電(dian)(dian)系(xi)統(tong)的(de)基(ji)本設(she)備(bei)包括光(guang)伏電(dian)(dian)池組件(jian)、光(guang)伏方陣支架、直(zhi)流(liu)匯(hui)流(liu)箱、直(zhi)流(liu)配(pei)(pei)電(dian)(dian)柜(ju)、并網逆變器、交流(liu)配(pei)(pei)電(dian)(dian)柜(ju)等設(she)備(bei)，另外還有供電(dian)(dian)系(xi)統(tong)監控裝置(zhi)和環境監測裝置(zhi)。其運行模式(shi)是在有太陽(yang)輻射的(de)條(tiao)件(jian)下，光(guang)伏發電(dian)(dian)系(xi)統(tong)的(de)太陽(yang)能(neng)電(dian)(dian)池組件(jian)陣列將太陽(yang)能(neng)轉換輸(shu)出的(de)電(dian)(dian)能(neng)，經過(guo)直(zhi)流(liu)匯(hui)流(liu)箱集中送入直(zhi)流(liu)配(pei)(pei)電(dian)(dian)柜(ju)，由并網逆變器逆變成交流(liu)電(dian)(dian)供給建筑自(zi)身負載(zai)，多余或不(bu)足的(de)電(dian)(dian)力通(tong)過(guo)聯接電(dian)(dian)網來調節。
