山東省青州市魯東機械2.1MW光(guang)伏(fu)(fu)發(fa)電站項目(mu)。彩鋼瓦屋(wu)頂光(guang)伏(fu)(fu)發(fa)電站，已(yi)并網發(fa)電成(cheng)功！

輸送方式

太陽能光伏(fu)發電(dian)分為(wei)獨立光伏(fu)發電(dian)、并網光伏(fu)發電(dian)、分布式光伏(fu)發電(dian)

獨立光伏發電

獨立(li)光伏發電系統也叫離網(wang)光伏發電系統。主要由太陽能電池組件、控(kong)制器、蓄電池組成，若要為交流負載供(gong)電，還需要配置(zhi)交流逆(ni)變器。

并網光伏發電

并網(wang)光(guang)(guang)(guang)(guang)伏發電(dian)(dian)(dian)(dian)(dian)系統(tong)就(jiu)是(shi)太(tai)陽能(neng)組件(jian)產生的直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)經過并網(wang)逆變器轉換成符合市(shi)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)網(wang)要求的交流(liu)電(dian)(dian)(dian)(dian)(dian)之后直(zhi)接接入公共電(dian)(dian)(dian)(dian)(dian)網(wang)。并網(wang)光(guang)(guang)(guang)(guang)伏發電(dian)(dian)(dian)(dian)(dian)系統(tong)有集(ji)中式大(da)型并網(wang)光(guang)(guang)(guang)(guang)伏電(dian)(dian)(dian)(dian)(dian)站一般都是(shi)國(guo)家級電(dian)(dian)(dian)(dian)(dian)站，主要特點是(shi)將所發電(dian)(dian)(dian)(dian)(dian)能(neng)直(zhi)接輸送(song)到電(dian)(dian)(dian)(dian)(dian)網(wang)，由(you)(you)電(dian)(dian)(dian)(dian)(dian)網(wang)統(tong)一調(diao)配(pei)向用戶供(gong)電(dian)(dian)(dian)(dian)(dian)。但這種(zhong)電(dian)(dian)(dian)(dian)(dian)站投(tou)資大(da)、建(jian)(jian)設(she)周期長、占(zhan)地(di)面積大(da)，發展難度相對較(jiao)大(da)。而分(fen)散式小型并網(wang)光(guang)(guang)(guang)(guang)伏系統(tong)，特別是(shi)光(guang)(guang)(guang)(guang)伏建(jian)(jian)筑一體化發電(dian)(dian)(dian)(dian)(dian)系統(tong)，由(you)(you)于(yu)投(tou)資小、建(jian)(jian)設(she)快(kuai)、占(zhan)地(di)面積小、政策(ce)支持力度大(da)等優點，是(shi)并網(wang)光(guang)(guang)(guang)(guang)伏發電(dian)(dian)(dian)(dian)(dian)的主流(liu)。

分布式光伏發電

分布式光伏發電(dian)系(xi)統，又稱分散式發電(dian)或(huo)分布式供能，是指在用戶(hu)現(xian)(xian)場或(huo)靠近用電(dian)現(xian)(xian)場配置較小的(de)光伏發電(dian)供電(dian)系(xi)統，以滿足(zu)特定用戶(hu)的(de)需求(qiu)，支持現(xian)(xian)存(cun)配電(dian)網的(de)經濟(ji)運行，或(huo)者同時滿足(zu)這兩個方面的(de)要(yao)求(qiu)。

　　分布式光(guang)(guang)伏發(fa)(fa)電系(xi)統的基本設(she)(she)備(bei)包括光(guang)(guang)伏電池(chi)組件(jian)、光(guang)(guang)伏方陣支架、直流(liu)匯流(liu)箱、直流(liu)配電柜、并(bing)網逆變器、交(jiao)流(liu)配電柜等設(she)(she)備(bei)，另外還(huan)有(you)(you)供(gong)電系(xi)統監控裝置(zhi)和環境監測(ce)裝置(zhi)。其運行模式是在有(you)(you)太陽輻射(she)的條(tiao)件(jian)下，光(guang)(guang)伏發(fa)(fa)電系(xi)統的太陽能(neng)電池(chi)組件(jian)陣列將(jiang)太陽能(neng)轉換輸出的電能(neng)，經過直流(liu)匯流(liu)箱集中送入直流(liu)配電柜，由(you)并(bing)網逆變器逆變成(cheng)交(jiao)流(liu)電供(gong)給建筑自身負載(zai)，多余或不足的電力通過聯(lian)接(jie)電網來調節。
