山(shan)東(dong)省青州市(shi)魯(lu)東(dong)機械2.1MW光伏(fu)發電(dian)站(zhan)項目。彩(cai)鋼瓦屋頂光伏(fu)發電(dian)站(zhan)，已(yi)并網發電(dian)成功！

輸送方式

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

獨立光伏發電

獨立光伏(fu)發電系統(tong)也叫離網光伏(fu)發電系統(tong)。主(zhu)要(yao)由太陽(yang)能電池(chi)組(zu)件、控制器(qi)、蓄電池(chi)組(zu)成，若要(yao)為(wei)交流負(fu)載供(gong)電，還需要(yao)配(pei)置交流逆變器(qi)。

并網光伏發電

并(bing)網(wang)(wang)光(guang)(guang)伏(fu)發(fa)電(dian)(dian)(dian)系(xi)(xi)統(tong)就是太陽能(neng)組件產生(sheng)的直流電(dian)(dian)(dian)經(jing)過并(bing)網(wang)(wang)逆變(bian)器(qi)轉換成符合市電(dian)(dian)(dian)電(dian)(dian)(dian)網(wang)(wang)要求的交(jiao)流電(dian)(dian)(dian)之后(hou)直接接入公共電(dian)(dian)(dian)網(wang)(wang)。并(bing)網(wang)(wang)光(guang)(guang)伏(fu)發(fa)電(dian)(dian)(dian)系(xi)(xi)統(tong)有集中式(shi)(shi)大(da)型并(bing)網(wang)(wang)光(guang)(guang)伏(fu)電(dian)(dian)(dian)站(zhan)(zhan)一(yi)般都是國家級電(dian)(dian)(dian)站(zhan)(zhan)，主要特點(dian)是將所發(fa)電(dian)(dian)(dian)能(neng)直接輸送到(dao)電(dian)(dian)(dian)網(wang)(wang)，由(you)電(dian)(dian)(dian)網(wang)(wang)統(tong)一(yi)調配向(xiang)用戶供電(dian)(dian)(dian)。但這種電(dian)(dian)(dian)站(zhan)(zhan)投資大(da)、建設周期(qi)長(chang)、占地面積(ji)大(da)，發(fa)展難度相(xiang)對較大(da)。而分散式(shi)(shi)小(xiao)(xiao)型并(bing)網(wang)(wang)光(guang)(guang)伏(fu)系(xi)(xi)統(tong)，特別(bie)是光(guang)(guang)伏(fu)建筑一(yi)體化發(fa)電(dian)(dian)(dian)系(xi)(xi)統(tong)，由(you)于(yu)投資小(xiao)(xiao)、建設快、占地面積(ji)小(xiao)(xiao)、政策支持力(li)度大(da)等優點(dian)，是并(bing)網(wang)(wang)光(guang)(guang)伏(fu)發(fa)電(dian)(dian)(dian)的主流。

分布式光伏發電

分(fen)布(bu)式光(guang)(guang)伏發電系統，又稱(cheng)分(fen)散(san)式發電或(huo)分(fen)布(bu)式供能，是(shi)指在(zai)用(yong)(yong)戶現(xian)(xian)場或(huo)靠近用(yong)(yong)電現(xian)(xian)場配置較小的(de)光(guang)(guang)伏發電供電系統，以(yi)滿(man)足特(te)定用(yong)(yong)戶的(de)需(xu)求(qiu)(qiu)，支持(chi)現(xian)(xian)存配電網(wang)的(de)經濟運行，或(huo)者同時滿(man)足這兩個方面的(de)要求(qiu)(qiu)。

　　分布式(shi)光(guang)(guang)伏(fu)發(fa)電(dian)(dian)系統的基本設(she)(she)備包括光(guang)(guang)伏(fu)電(dian)(dian)池組件、光(guang)(guang)伏(fu)方陣(zhen)支架、直流(liu)(liu)匯流(liu)(liu)箱(xiang)、直流(liu)(liu)配電(dian)(dian)柜、并(bing)網逆(ni)變器、交流(liu)(liu)配電(dian)(dian)柜等設(she)(she)備，另外還有供電(dian)(dian)系統監(jian)控裝(zhuang)置和(he)環境(jing)監(jian)測裝(zhuang)置。其運行模式(shi)是(shi)在有太陽(yang)輻射的條件下，光(guang)(guang)伏(fu)發(fa)電(dian)(dian)系統的太陽(yang)能(neng)電(dian)(dian)池組件陣(zhen)列將(jiang)太陽(yang)能(neng)轉(zhuan)換輸出的電(dian)(dian)能(neng)，經過直流(liu)(liu)匯流(liu)(liu)箱(xiang)集中送入直流(liu)(liu)配電(dian)(dian)柜，由并(bing)網逆(ni)變器逆(ni)變成交流(liu)(liu)電(dian)(dian)供給建(jian)筑自身負載(zai)，多余或(huo)不足的電(dian)(dian)力通過聯接(jie)電(dian)(dian)網來調節。
