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

輸送方式

太陽(yang)能光(guang)伏(fu)發(fa)電(dian)分為(wei)獨立光(guang)伏(fu)發(fa)電(dian)、并網光(guang)伏(fu)發(fa)電(dian)、分布(bu)式光(guang)伏(fu)發(fa)電(dian)

獨立光伏發電

獨立光伏(fu)發電(dian)系(xi)統也叫(jiao)離(li)網(wang)光伏(fu)發電(dian)系(xi)統。主要(yao)(yao)由太陽能電(dian)池組件、控制(zhi)器、蓄電(dian)池組成，若要(yao)(yao)為(wei)交流負載供電(dian)，還需要(yao)(yao)配(pei)置交流逆(ni)變器。

并網光伏發電

并(bing)網(wang)(wang)(wang)光(guang)伏(fu)(fu)(fu)(fu)發(fa)電(dian)(dian)系(xi)統(tong)(tong)就是太陽能(neng)組件(jian)產(chan)生的直流電(dian)(dian)經過并(bing)網(wang)(wang)(wang)逆變器轉換成符(fu)合市電(dian)(dian)電(dian)(dian)網(wang)(wang)(wang)要求的交(jiao)流電(dian)(dian)之(zhi)后(hou)直接(jie)接(jie)入(ru)公(gong)共電(dian)(dian)網(wang)(wang)(wang)。并(bing)網(wang)(wang)(wang)光(guang)伏(fu)(fu)(fu)(fu)發(fa)電(dian)(dian)系(xi)統(tong)(tong)有集(ji)中式大型并(bing)網(wang)(wang)(wang)光(guang)伏(fu)(fu)(fu)(fu)電(dian)(dian)站(zhan)一般都是國家級電(dian)(dian)站(zhan)，主要特點是將(jiang)所(suo)發(fa)電(dian)(dian)能(neng)直接(jie)輸送到電(dian)(dian)網(wang)(wang)(wang)，由電(dian)(dian)網(wang)(wang)(wang)統(tong)(tong)一調配向(xiang)用(yong)戶供電(dian)(dian)。但這種(zhong)電(dian)(dian)站(zhan)投(tou)資大、建設(she)周期長、占(zhan)(zhan)地面積大，發(fa)展難(nan)度相對較大。而分散式小(xiao)型并(bing)網(wang)(wang)(wang)光(guang)伏(fu)(fu)(fu)(fu)系(xi)統(tong)(tong)，特別是光(guang)伏(fu)(fu)(fu)(fu)建筑一體化發(fa)電(dian)(dian)系(xi)統(tong)(tong)，由于投(tou)資小(xiao)、建設(she)快、占(zhan)(zhan)地面積小(xiao)、政(zheng)策支(zhi)持力(li)度大等優點，是并(bing)網(wang)(wang)(wang)光(guang)伏(fu)(fu)(fu)(fu)發(fa)電(dian)(dian)的主流。

分布式光伏發電

分布式光(guang)伏發電(dian)(dian)系統(tong)，又稱分散(san)式發電(dian)(dian)或(huo)分布式供能，是指在用(yong)戶現場(chang)或(huo)靠近(jin)用(yong)電(dian)(dian)現場(chang)配置(zhi)較小(xiao)的光(guang)伏發電(dian)(dian)供電(dian)(dian)系統(tong)，以(yi)滿(man)足特定用(yong)戶的需求(qiu)，支持現存配電(dian)(dian)網的經濟運行，或(huo)者同(tong)時(shi)滿(man)足這兩個方(fang)面(mian)的要(yao)求(qiu)。

　　分布式光(guang)伏(fu)發電(dian)(dian)系(xi)統(tong)的(de)(de)基本(ben)設備(bei)包括光(guang)伏(fu)電(dian)(dian)池(chi)組件、光(guang)伏(fu)方(fang)陣支架、直(zhi)流(liu)(liu)匯流(liu)(liu)箱(xiang)、直(zhi)流(liu)(liu)配(pei)(pei)電(dian)(dian)柜、并(bing)網逆(ni)變(bian)器、交(jiao)流(liu)(liu)配(pei)(pei)電(dian)(dian)柜等設備(bei)，另外還有(you)供(gong)電(dian)(dian)系(xi)統(tong)監控裝置(zhi)和環(huan)境監測裝置(zhi)。其運行模式是在有(you)太陽(yang)(yang)輻射(she)的(de)(de)條件下(xia)，光(guang)伏(fu)發電(dian)(dian)系(xi)統(tong)的(de)(de)太陽(yang)(yang)能(neng)電(dian)(dian)池(chi)組件陣列將太陽(yang)(yang)能(neng)轉換輸出的(de)(de)電(dian)(dian)能(neng)，經過(guo)直(zhi)流(liu)(liu)匯流(liu)(liu)箱(xiang)集中送入直(zhi)流(liu)(liu)配(pei)(pei)電(dian)(dian)柜，由(you)并(bing)網逆(ni)變(bian)器逆(ni)變(bian)成(cheng)交(jiao)流(liu)(liu)電(dian)(dian)供(gong)給建(jian)筑自身負載，多余(yu)或不(bu)足(zu)的(de)(de)電(dian)(dian)力(li)通(tong)過(guo)聯接電(dian)(dian)網來調節。
