山東省青(qing)州(zhou)市魯(lu)東機械(xie)2.1MW光伏發(fa)電(dian)(dian)站(zhan)項目。彩鋼瓦屋頂光伏發(fa)電(dian)(dian)站(zhan)，已并網(wang)發(fa)電(dian)(dian)成功！

輸送方式

太(tai)陽能光(guang)(guang)伏(fu)(fu)發(fa)(fa)電(dian)分為獨立光(guang)(guang)伏(fu)(fu)發(fa)(fa)電(dian)、并網(wang)光(guang)(guang)伏(fu)(fu)發(fa)(fa)電(dian)、分布式光(guang)(guang)伏(fu)(fu)發(fa)(fa)電(dian)

獨立光伏發電

獨(du)立光(guang)伏發電(dian)(dian)系(xi)統(tong)也叫離網光(guang)伏發電(dian)(dian)系(xi)統(tong)。主(zhu)要(yao)由太陽能電(dian)(dian)池組件、控制器、蓄電(dian)(dian)池組成(cheng)，若要(yao)為(wei)交(jiao)流負載供電(dian)(dian)，還需要(yao)配置交(jiao)流逆變器。

并網光伏發電

并(bing)(bing)網(wang)光伏(fu)發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)系(xi)統就是(shi)太陽能組(zu)件產生的(de)直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)經過(guo)并(bing)(bing)網(wang)逆變器(qi)轉換成符(fu)合市電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)要求(qiu)的(de)交流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)之后直接(jie)接(jie)入公(gong)共(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)。并(bing)(bing)網(wang)光伏(fu)發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)系(xi)統有集(ji)中(zhong)式大(da)(da)型并(bing)(bing)網(wang)光伏(fu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)站一(yi)般都是(shi)國家級電(dian)(dian)(dian)(dian)(dian)(dian)(dian)站，主要特點是(shi)將(jiang)所發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能直接(jie)輸(shu)送到電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)，由電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)統一(yi)調配(pei)向(xiang)用戶供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。但這種電(dian)(dian)(dian)(dian)(dian)(dian)(dian)站投(tou)資(zi)大(da)(da)、建設(she)周(zhou)期長、占(zhan)地面積大(da)(da)，發展難度相對較大(da)(da)。而分散式小型并(bing)(bing)網(wang)光伏(fu)系(xi)統，特別是(shi)光伏(fu)建筑(zhu)一(yi)體(ti)化發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)系(xi)統，由于(yu)投(tou)資(zi)小、建設(she)快、占(zhan)地面積小、政策支持力度大(da)(da)等(deng)優(you)點，是(shi)并(bing)(bing)網(wang)光伏(fu)發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)主流(liu)。

分布式光伏發電

分(fen)布式(shi)(shi)光伏發(fa)(fa)電(dian)(dian)系(xi)統(tong)，又稱分(fen)散式(shi)(shi)發(fa)(fa)電(dian)(dian)或(huo)分(fen)布式(shi)(shi)供(gong)(gong)能，是指(zhi)在用(yong)戶現場或(huo)靠近用(yong)電(dian)(dian)現場配(pei)置(zhi)較小(xiao)的(de)光伏發(fa)(fa)電(dian)(dian)供(gong)(gong)電(dian)(dian)系(xi)統(tong)，以滿足(zu)特(te)定用(yong)戶的(de)需求，支持現存配(pei)電(dian)(dian)網的(de)經濟運行(xing)，或(huo)者同時滿足(zu)這兩個方面的(de)要求。

　　分布式光(guang)伏發電(dian)(dian)系統(tong)的(de)(de)基本設備包括光(guang)伏電(dian)(dian)池組件、光(guang)伏方(fang)陣支架、直(zhi)流(liu)匯流(liu)箱(xiang)(xiang)、直(zhi)流(liu)配(pei)電(dian)(dian)柜、并(bing)網逆變器、交(jiao)流(liu)配(pei)電(dian)(dian)柜等設備，另外還有供電(dian)(dian)系統(tong)監控裝置(zhi)和環境監測裝置(zhi)。其(qi)運行模(mo)式是在有太(tai)陽(yang)輻(fu)射的(de)(de)條(tiao)件下(xia)，光(guang)伏發電(dian)(dian)系統(tong)的(de)(de)太(tai)陽(yang)能電(dian)(dian)池組件陣列(lie)將太(tai)陽(yang)能轉換輸出的(de)(de)電(dian)(dian)能，經過(guo)(guo)直(zhi)流(liu)匯流(liu)箱(xiang)(xiang)集中送入直(zhi)流(liu)配(pei)電(dian)(dian)柜，由并(bing)網逆變器逆變成交(jiao)流(liu)電(dian)(dian)供給建筑自身負載，多余或不(bu)足(zu)的(de)(de)電(dian)(dian)力通過(guo)(guo)聯接電(dian)(dian)網來調節。
