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

輸送方式

太陽(yang)能光(guang)伏(fu)發電分為獨立光(guang)伏(fu)發電、并網光(guang)伏(fu)發電、分布(bu)式(shi)光(guang)伏(fu)發電

獨立光伏發電

獨立(li)光伏發電(dian)(dian)(dian)系統也叫離網(wang)光伏發電(dian)(dian)(dian)系統。主要(yao)(yao)由太(tai)陽能電(dian)(dian)(dian)池(chi)組(zu)件、控制器、蓄電(dian)(dian)(dian)池(chi)組(zu)成，若要(yao)(yao)為(wei)交流負載(zai)供電(dian)(dian)(dian)，還需要(yao)(yao)配置交流逆變器。

并網光伏發電

并(bing)網(wang)光(guang)伏發電(dian)(dian)(dian)(dian)系統(tong)就是(shi)(shi)太(tai)陽能(neng)(neng)組件(jian)產(chan)生(sheng)的(de)直流電(dian)(dian)(dian)(dian)經過并(bing)網(wang)逆變器(qi)轉換(huan)成符合(he)市(shi)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)網(wang)要(yao)求(qiu)的(de)交(jiao)流電(dian)(dian)(dian)(dian)之后直接接入公(gong)共電(dian)(dian)(dian)(dian)網(wang)。并(bing)網(wang)光(guang)伏發電(dian)(dian)(dian)(dian)系統(tong)有集中式大型(xing)(xing)并(bing)網(wang)光(guang)伏電(dian)(dian)(dian)(dian)站一般都是(shi)(shi)國家級電(dian)(dian)(dian)(dian)站，主要(yao)特點是(shi)(shi)將所發電(dian)(dian)(dian)(dian)能(neng)(neng)直接輸送到(dao)電(dian)(dian)(dian)(dian)網(wang)，由電(dian)(dian)(dian)(dian)網(wang)統(tong)一調配向用戶供(gong)電(dian)(dian)(dian)(dian)。但這種電(dian)(dian)(dian)(dian)站投資大、建設周期(qi)長、占(zhan)地面積(ji)大，發展難度相對較大。而分(fen)散式小(xiao)型(xing)(xing)并(bing)網(wang)光(guang)伏系統(tong)，特別是(shi)(shi)光(guang)伏建筑(zhu)一體化(hua)發電(dian)(dian)(dian)(dian)系統(tong)，由于投資小(xiao)、建設快、占(zhan)地面積(ji)小(xiao)、政策支持(chi)力(li)度大等優點，是(shi)(shi)并(bing)網(wang)光(guang)伏發電(dian)(dian)(dian)(dian)的(de)主流。

分布式光伏發電

分布(bu)式光伏發(fa)電(dian)(dian)系統，又稱分散式發(fa)電(dian)(dian)或(huo)分布(bu)式供(gong)能，是指在用戶(hu)現(xian)場或(huo)靠近(jin)用電(dian)(dian)現(xian)場配置較小的光伏發(fa)電(dian)(dian)供(gong)電(dian)(dian)系統，以滿足特定用戶(hu)的需求(qiu)，支持現(xian)存配電(dian)(dian)網(wang)的經濟運行，或(huo)者同時滿足這(zhe)兩個方面的要求(qiu)。

　　分(fen)布式光伏發電(dian)(dian)系統的(de)基(ji)本(ben)設備(bei)包括(kuo)光伏電(dian)(dian)池(chi)組件、光伏方陣(zhen)支(zhi)架、直流(liu)(liu)匯(hui)流(liu)(liu)箱(xiang)、直流(liu)(liu)配電(dian)(dian)柜、并(bing)網逆(ni)變器(qi)、交(jiao)(jiao)流(liu)(liu)配電(dian)(dian)柜等設備(bei)，另外(wai)還有供電(dian)(dian)系統監控(kong)裝置(zhi)和(he)環境監測裝置(zhi)。其運行模式是在(zai)有太(tai)陽(yang)輻射(she)的(de)條件下，光伏發電(dian)(dian)系統的(de)太(tai)陽(yang)能電(dian)(dian)池(chi)組件陣(zhen)列將太(tai)陽(yang)能轉換輸出的(de)電(dian)(dian)能，經過直流(liu)(liu)匯(hui)流(liu)(liu)箱(xiang)集中(zhong)送(song)入直流(liu)(liu)配電(dian)(dian)柜，由(you)并(bing)網逆(ni)變器(qi)逆(ni)變成交(jiao)(jiao)流(liu)(liu)電(dian)(dian)供給建筑自身負載，多余或不足的(de)電(dian)(dian)力通過聯接電(dian)(dian)網來調節。
