山東省青州(zhou)市魯東機械2.1MW光(guang)伏(fu)發(fa)(fa)電站(zhan)項(xiang)目(mu)。彩鋼瓦屋頂光(guang)伏(fu)發(fa)(fa)電站(zhan)，已并網發(fa)(fa)電成功！

輸送方式

太(tai)陽能光(guang)伏(fu)發電分(fen)為獨立(li)光(guang)伏(fu)發電、并網光(guang)伏(fu)發電、分(fen)布式光(guang)伏(fu)發電

獨立光伏發電

獨(du)立光伏發電系統(tong)也叫離網光伏發電系統(tong)。主要由太陽能電池組(zu)件、控(kong)制(zhi)器、蓄電池組(zu)成，若(ruo)要為交流負載供(gong)電，還需要配置(zhi)交流逆變(bian)器。

并網光伏發電

并網(wang)光(guang)伏(fu)(fu)發電(dian)(dian)(dian)系統就是(shi)太陽能組件(jian)產(chan)生的(de)(de)(de)直(zhi)流(liu)(liu)電(dian)(dian)(dian)經過(guo)并網(wang)逆變器轉換(huan)成(cheng)符合市電(dian)(dian)(dian)電(dian)(dian)(dian)網(wang)要(yao)求的(de)(de)(de)交流(liu)(liu)電(dian)(dian)(dian)之后直(zhi)接接入公共(gong)電(dian)(dian)(dian)網(wang)。并網(wang)光(guang)伏(fu)(fu)發電(dian)(dian)(dian)系統有集(ji)中(zhong)式大(da)(da)型并網(wang)光(guang)伏(fu)(fu)電(dian)(dian)(dian)站一般(ban)都是(shi)國(guo)家級電(dian)(dian)(dian)站，主要(yao)特(te)點(dian)(dian)是(shi)將所發電(dian)(dian)(dian)能直(zhi)接輸(shu)送到(dao)電(dian)(dian)(dian)網(wang)，由電(dian)(dian)(dian)網(wang)統一調配向用戶(hu)供(gong)電(dian)(dian)(dian)。但這種電(dian)(dian)(dian)站投(tou)資大(da)(da)、建設周期長(chang)、占地面積大(da)(da)，發展難度(du)相(xiang)對較(jiao)大(da)(da)。而(er)分散式小型并網(wang)光(guang)伏(fu)(fu)系統，特(te)別是(shi)光(guang)伏(fu)(fu)建筑一體化發電(dian)(dian)(dian)系統，由于投(tou)資小、建設快(kuai)、占地面積小、政策支持(chi)力度(du)大(da)(da)等(deng)優點(dian)(dian)，是(shi)并網(wang)光(guang)伏(fu)(fu)發電(dian)(dian)(dian)的(de)(de)(de)主流(liu)(liu)。

分布式光伏發電

分(fen)布式(shi)光伏發(fa)電(dian)系統，又稱分(fen)散式(shi)發(fa)電(dian)或(huo)分(fen)布式(shi)供能，是(shi)指在用(yong)戶(hu)現場或(huo)靠近用(yong)電(dian)現場配置(zhi)較小的(de)光伏發(fa)電(dian)供電(dian)系統，以滿足特定用(yong)戶(hu)的(de)需求，支持現存配電(dian)網的(de)經濟運行，或(huo)者(zhe)同時滿足這兩個方面的(de)要求。

　　分布式(shi)光伏發(fa)電(dian)(dian)(dian)(dian)系統(tong)的(de)(de)基本設(she)備包(bao)括光伏電(dian)(dian)(dian)(dian)池組(zu)件(jian)、光伏方陣(zhen)支架、直(zhi)流(liu)(liu)匯流(liu)(liu)箱(xiang)、直(zhi)流(liu)(liu)配電(dian)(dian)(dian)(dian)柜(ju)、并(bing)網逆變(bian)器、交(jiao)流(liu)(liu)配電(dian)(dian)(dian)(dian)柜(ju)等設(she)備，另外還有供(gong)電(dian)(dian)(dian)(dian)系統(tong)監控裝(zhuang)置(zhi)和環境(jing)監測裝(zhuang)置(zhi)。其運行模式(shi)是在有太(tai)陽(yang)輻射的(de)(de)條(tiao)件(jian)下，光伏發(fa)電(dian)(dian)(dian)(dian)系統(tong)的(de)(de)太(tai)陽(yang)能電(dian)(dian)(dian)(dian)池組(zu)件(jian)陣(zhen)列將太(tai)陽(yang)能轉換(huan)輸出的(de)(de)電(dian)(dian)(dian)(dian)能，經過(guo)直(zhi)流(liu)(liu)匯流(liu)(liu)箱(xiang)集(ji)中送入直(zhi)流(liu)(liu)配電(dian)(dian)(dian)(dian)柜(ju)，由并(bing)網逆變(bian)器逆變(bian)成交(jiao)流(liu)(liu)電(dian)(dian)(dian)(dian)供(gong)給建筑自身負載，多余或不足的(de)(de)電(dian)(dian)(dian)(dian)力通過(guo)聯接電(dian)(dian)(dian)(dian)網來調節(jie)。
