山(shan)東省青州市魯東機械2.1MW光(guang)伏(fu)(fu)發(fa)電(dian)站項(xiang)目(mu)。彩鋼瓦(wa)屋頂光(guang)伏(fu)(fu)發(fa)電(dian)站，已并網發(fa)電(dian)成功(gong)！

輸送方式

太陽能(neng)光(guang)伏(fu)發(fa)電(dian)分為獨立光(guang)伏(fu)發(fa)電(dian)、并網光(guang)伏(fu)發(fa)電(dian)、分布式光(guang)伏(fu)發(fa)電(dian)

獨立光伏發電

獨(du)立光(guang)伏發(fa)電(dian)系統也叫離網光(guang)伏發(fa)電(dian)系統。主(zhu)要(yao)由太陽能電(dian)池組(zu)(zu)件(jian)、控制器(qi)、蓄電(dian)池組(zu)(zu)成(cheng)，若要(yao)為交(jiao)流負載(zai)供電(dian)，還需要(yao)配置交(jiao)流逆變(bian)器(qi)。

并網光伏發電

并(bing)網光(guang)伏發(fa)(fa)電(dian)(dian)(dian)系統就是太陽能(neng)組件產生的直(zhi)(zhi)流電(dian)(dian)(dian)經(jing)過并(bing)網逆(ni)變器轉換成符(fu)合(he)市電(dian)(dian)(dian)電(dian)(dian)(dian)網要求(qiu)的交流電(dian)(dian)(dian)之(zhi)后直(zhi)(zhi)接(jie)接(jie)入公共電(dian)(dian)(dian)網。并(bing)網光(guang)伏發(fa)(fa)電(dian)(dian)(dian)系統有(you)集中式(shi)大(da)型(xing)(xing)并(bing)網光(guang)伏電(dian)(dian)(dian)站(zhan)一般(ban)都是國家(jia)級(ji)電(dian)(dian)(dian)站(zhan)，主(zhu)要特(te)點是將所發(fa)(fa)電(dian)(dian)(dian)能(neng)直(zhi)(zhi)接(jie)輸送到電(dian)(dian)(dian)網，由(you)電(dian)(dian)(dian)網統一調配向(xiang)用戶供電(dian)(dian)(dian)。但(dan)這種電(dian)(dian)(dian)站(zhan)投資大(da)、建(jian)(jian)設周期(qi)長、占地面積大(da)，發(fa)(fa)展難度(du)相對較大(da)。而分散(san)式(shi)小型(xing)(xing)并(bing)網光(guang)伏系統，特(te)別是光(guang)伏建(jian)(jian)筑一體化發(fa)(fa)電(dian)(dian)(dian)系統，由(you)于投資小、建(jian)(jian)設快、占地面積小、政策支持力(li)度(du)大(da)等優點，是并(bing)網光(guang)伏發(fa)(fa)電(dian)(dian)(dian)的主(zhu)流。

分布式光伏發電

分(fen)(fen)布(bu)式光伏(fu)發(fa)電(dian)系統(tong)，又稱分(fen)(fen)散式發(fa)電(dian)或分(fen)(fen)布(bu)式供(gong)能(neng)，是指在用戶現(xian)場(chang)或靠近用電(dian)現(xian)場(chang)配置較小的(de)光伏(fu)發(fa)電(dian)供(gong)電(dian)系統(tong)，以滿(man)足特定用戶的(de)需(xu)求(qiu)，支(zhi)持現(xian)存配電(dian)網的(de)經濟運行，或者同(tong)時滿(man)足這兩(liang)個方面(mian)的(de)要求(qiu)。

　　分布式光(guang)伏(fu)(fu)發(fa)(fa)電(dian)(dian)(dian)(dian)系統的(de)基本設(she)(she)備包(bao)括光(guang)伏(fu)(fu)電(dian)(dian)(dian)(dian)池組件、光(guang)伏(fu)(fu)方陣(zhen)支架(jia)、直(zhi)(zhi)(zhi)流(liu)(liu)匯(hui)流(liu)(liu)箱(xiang)、直(zhi)(zhi)(zhi)流(liu)(liu)配(pei)電(dian)(dian)(dian)(dian)柜、并(bing)網(wang)逆變器(qi)、交流(liu)(liu)配(pei)電(dian)(dian)(dian)(dian)柜等設(she)(she)備，另(ling)外還有供電(dian)(dian)(dian)(dian)系統監控裝置和環(huan)境監測裝置。其運行(xing)模式是在有太陽輻射(she)的(de)條件下，光(guang)伏(fu)(fu)發(fa)(fa)電(dian)(dian)(dian)(dian)系統的(de)太陽能電(dian)(dian)(dian)(dian)池組件陣(zhen)列(lie)將太陽能轉換輸(shu)出的(de)電(dian)(dian)(dian)(dian)能，經過直(zhi)(zhi)(zhi)流(liu)(liu)匯(hui)流(liu)(liu)箱(xiang)集中(zhong)送入直(zhi)(zhi)(zhi)流(liu)(liu)配(pei)電(dian)(dian)(dian)(dian)柜，由并(bing)網(wang)逆變器(qi)逆變成交流(liu)(liu)電(dian)(dian)(dian)(dian)供給建筑自身負載，多余(yu)或不足的(de)電(dian)(dian)(dian)(dian)力通過聯接(jie)電(dian)(dian)(dian)(dian)網(wang)來調節。
