山東省青(qing)州市魯東機械2.1MW光伏發(fa)電(dian)站項目。彩鋼瓦(wa)屋頂光伏發(fa)電(dian)站，已并網發(fa)電(dian)成功！

輸送方式

太陽能光(guang)伏(fu)(fu)發電分為獨立光(guang)伏(fu)(fu)發電、并網光(guang)伏(fu)(fu)發電、分布式(shi)光(guang)伏(fu)(fu)發電

獨立光伏發電

獨立光伏發電(dian)系(xi)統也叫(jiao)離網光伏發電(dian)系(xi)統。主要由太陽能電(dian)池(chi)組(zu)件、控制器、蓄電(dian)池(chi)組(zu)成，若要為交流(liu)負載供電(dian)，還需要配置交流(liu)逆變器。

并網光伏發電

并(bing)網光(guang)(guang)(guang)伏(fu)(fu)發(fa)電(dian)(dian)(dian)系統就是(shi)太(tai)陽能組件(jian)產生的(de)直(zhi)流電(dian)(dian)(dian)經(jing)過并(bing)網逆變器轉換成(cheng)符(fu)合市電(dian)(dian)(dian)電(dian)(dian)(dian)網要求的(de)交(jiao)流電(dian)(dian)(dian)之后直(zhi)接(jie)接(jie)入公共電(dian)(dian)(dian)網。并(bing)網光(guang)(guang)(guang)伏(fu)(fu)發(fa)電(dian)(dian)(dian)系統有(you)集中式大(da)(da)型并(bing)網光(guang)(guang)(guang)伏(fu)(fu)電(dian)(dian)(dian)站(zhan)一般都是(shi)國家級電(dian)(dian)(dian)站(zhan)，主要特點(dian)是(shi)將所發(fa)電(dian)(dian)(dian)能直(zhi)接(jie)輸送到電(dian)(dian)(dian)網，由(you)電(dian)(dian)(dian)網統一調配(pei)向用(yong)戶供電(dian)(dian)(dian)。但這種電(dian)(dian)(dian)站(zhan)投(tou)資大(da)(da)、建設周期長、占(zhan)地(di)(di)面積大(da)(da)，發(fa)展難度相(xiang)對(dui)較大(da)(da)。而分散式小型并(bing)網光(guang)(guang)(guang)伏(fu)(fu)系統，特別是(shi)光(guang)(guang)(guang)伏(fu)(fu)建筑一體化發(fa)電(dian)(dian)(dian)系統，由(you)于投(tou)資小、建設快、占(zhan)地(di)(di)面積小、政(zheng)策支(zhi)持力度大(da)(da)等優點(dian)，是(shi)并(bing)網光(guang)(guang)(guang)伏(fu)(fu)發(fa)電(dian)(dian)(dian)的(de)主流。

分布式光伏發電

分布(bu)式光伏(fu)(fu)發電(dian)系統，又稱(cheng)分散式發電(dian)或分布(bu)式供(gong)能(neng)，是(shi)指在用戶(hu)現場或靠(kao)近用電(dian)現場配置較小的(de)光伏(fu)(fu)發電(dian)供(gong)電(dian)系統，以滿足特定用戶(hu)的(de)需求，支(zhi)持現存配電(dian)網的(de)經(jing)濟運行(xing)，或者同時滿足這兩個方面的(de)要求。

　　分(fen)布式光伏發電(dian)(dian)(dian)系統的基本設(she)備包括(kuo)光伏電(dian)(dian)(dian)池(chi)組件、光伏方陣(zhen)支架(jia)、直(zhi)流(liu)匯流(liu)箱、直(zhi)流(liu)配(pei)電(dian)(dian)(dian)柜、并網逆(ni)變器、交流(liu)配(pei)電(dian)(dian)(dian)柜等設(she)備，另外還(huan)有供(gong)電(dian)(dian)(dian)系統監控裝(zhuang)(zhuang)置和(he)環境監測(ce)裝(zhuang)(zhuang)置。其運(yun)行模(mo)式是在有太陽(yang)輻射的條件下，光伏發電(dian)(dian)(dian)系統的太陽(yang)能電(dian)(dian)(dian)池(chi)組件陣(zhen)列將(jiang)太陽(yang)能轉換輸出的電(dian)(dian)(dian)能，經過直(zhi)流(liu)匯流(liu)箱集中送入直(zhi)流(liu)配(pei)電(dian)(dian)(dian)柜，由(you)并網逆(ni)變器逆(ni)變成交流(liu)電(dian)(dian)(dian)供(gong)給建筑自身負(fu)載，多余或不(bu)足的電(dian)(dian)(dian)力(li)通過聯接(jie)電(dian)(dian)(dian)網來(lai)調節。
