山東省(sheng)青州市(shi)魯東機械2.1MW光伏發(fa)(fa)電站項目。彩(cai)鋼瓦屋頂光伏發(fa)(fa)電站，已(yi)并網發(fa)(fa)電成功！

輸送方式

太陽能光伏(fu)發(fa)(fa)(fa)電(dian)分(fen)為獨立光伏(fu)發(fa)(fa)(fa)電(dian)、并網光伏(fu)發(fa)(fa)(fa)電(dian)、分(fen)布式光伏(fu)發(fa)(fa)(fa)電(dian)

獨立光伏發電

獨立光(guang)伏發(fa)電(dian)系(xi)統也叫離網光(guang)伏發(fa)電(dian)系(xi)統。主(zhu)要由(you)太陽能電(dian)池組件、控制器(qi)、蓄電(dian)池組成，若要為(wei)交流負載供電(dian)，還需要配置交流逆變器(qi)。

并網光伏發電

并網(wang)(wang)光伏(fu)發電(dian)(dian)系統(tong)(tong)就是太陽能組件產生的直(zhi)流(liu)電(dian)(dian)經過并網(wang)(wang)逆變器轉換成符合市電(dian)(dian)電(dian)(dian)網(wang)(wang)要(yao)求的交流(liu)電(dian)(dian)之后直(zhi)接接入(ru)公共(gong)電(dian)(dian)網(wang)(wang)。并網(wang)(wang)光伏(fu)發電(dian)(dian)系統(tong)(tong)有集中(zhong)式大(da)(da)型(xing)(xing)并網(wang)(wang)光伏(fu)電(dian)(dian)站(zhan)一般都(dou)是國(guo)家級電(dian)(dian)站(zhan)，主(zhu)要(yao)特(te)點是將所發電(dian)(dian)能直(zhi)接輸(shu)送到電(dian)(dian)網(wang)(wang)，由電(dian)(dian)網(wang)(wang)統(tong)(tong)一調配向用戶供(gong)電(dian)(dian)。但這種電(dian)(dian)站(zhan)投資(zi)大(da)(da)、建(jian)設周期長、占(zhan)地面積(ji)大(da)(da)，發展難度相對較大(da)(da)。而分散式小型(xing)(xing)并網(wang)(wang)光伏(fu)系統(tong)(tong)，特(te)別是光伏(fu)建(jian)筑一體化發電(dian)(dian)系統(tong)(tong)，由于投資(zi)小、建(jian)設快、占(zhan)地面積(ji)小、政策(ce)支(zhi)持力度大(da)(da)等優點，是并網(wang)(wang)光伏(fu)發電(dian)(dian)的主(zhu)流(liu)。

分布式光伏發電

分布式光伏發(fa)電(dian)(dian)系統，又(you)稱分散(san)式發(fa)電(dian)(dian)或(huo)(huo)分布式供能，是指在(zai)用(yong)戶現場或(huo)(huo)靠近(jin)用(yong)電(dian)(dian)現場配置(zhi)較小的(de)光伏發(fa)電(dian)(dian)供電(dian)(dian)系統，以滿足(zu)特(te)定用(yong)戶的(de)需求(qiu)，支持現存配電(dian)(dian)網的(de)經(jing)濟運行，或(huo)(huo)者同時滿足(zu)這兩(liang)個方面的(de)要求(qiu)。

　　分(fen)布式光(guang)伏發電(dian)(dian)(dian)系統(tong)的基本設(she)備包括光(guang)伏電(dian)(dian)(dian)池組件(jian)、光(guang)伏方陣(zhen)支架、直流(liu)匯流(liu)箱(xiang)、直流(liu)配(pei)電(dian)(dian)(dian)柜、并(bing)網(wang)(wang)逆(ni)變(bian)器、交流(liu)配(pei)電(dian)(dian)(dian)柜等設(she)備，另外還有(you)供電(dian)(dian)(dian)系統(tong)監控(kong)裝(zhuang)置和環境監測裝(zhuang)置。其運(yun)行(xing)模式是在有(you)太(tai)陽輻射(she)的條(tiao)件(jian)下，光(guang)伏發電(dian)(dian)(dian)系統(tong)的太(tai)陽能電(dian)(dian)(dian)池組件(jian)陣(zhen)列將太(tai)陽能轉換(huan)輸出的電(dian)(dian)(dian)能，經過直流(liu)匯流(liu)箱(xiang)集中送入直流(liu)配(pei)電(dian)(dian)(dian)柜，由并(bing)網(wang)(wang)逆(ni)變(bian)器逆(ni)變(bian)成交流(liu)電(dian)(dian)(dian)供給建筑自身負載，多(duo)余或不足的電(dian)(dian)(dian)力通過聯接電(dian)(dian)(dian)網(wang)(wang)來調節。
