山(shan)東省青州市魯(lu)東機械2.1MW光(guang)伏(fu)發電(dian)(dian)站項目。彩鋼瓦屋頂(ding)光(guang)伏(fu)發電(dian)(dian)站，已并網發電(dian)(dian)成功！

輸送方式

太陽能光伏(fu)發(fa)電分為獨立(li)光伏(fu)發(fa)電、并網光伏(fu)發(fa)電、分布式光伏(fu)發(fa)電

獨立光伏發電

獨立(li)光(guang)(guang)伏發電(dian)系統也叫離網(wang)光(guang)(guang)伏發電(dian)系統。主要由太陽能(neng)電(dian)池組件、控制器、蓄電(dian)池組成，若(ruo)要為(wei)交(jiao)流(liu)負(fu)載供電(dian)，還需要配(pei)置(zhi)交(jiao)流(liu)逆變器。

并網光伏發電

并網(wang)(wang)(wang)光(guang)伏(fu)發(fa)(fa)電(dian)(dian)系(xi)(xi)統(tong)(tong)就是(shi)(shi)太陽能組件產生的直流(liu)電(dian)(dian)經過并網(wang)(wang)(wang)逆(ni)變器轉換成符合市電(dian)(dian)電(dian)(dian)網(wang)(wang)(wang)要求的交流(liu)電(dian)(dian)之后直接接入公共電(dian)(dian)網(wang)(wang)(wang)。并網(wang)(wang)(wang)光(guang)伏(fu)發(fa)(fa)電(dian)(dian)系(xi)(xi)統(tong)(tong)有集(ji)中(zhong)式大(da)型并網(wang)(wang)(wang)光(guang)伏(fu)電(dian)(dian)站(zhan)一(yi)般都是(shi)(shi)國家級(ji)電(dian)(dian)站(zhan)，主要特(te)點(dian)是(shi)(shi)將所(suo)發(fa)(fa)電(dian)(dian)能直接輸送到電(dian)(dian)網(wang)(wang)(wang)，由(you)電(dian)(dian)網(wang)(wang)(wang)統(tong)(tong)一(yi)調配向(xiang)用戶供電(dian)(dian)。但這種電(dian)(dian)站(zhan)投資大(da)、建設周期長、占地面(mian)積大(da)，發(fa)(fa)展難度(du)相對較(jiao)大(da)。而分散式小型并網(wang)(wang)(wang)光(guang)伏(fu)系(xi)(xi)統(tong)(tong)，特(te)別是(shi)(shi)光(guang)伏(fu)建筑一(yi)體(ti)化發(fa)(fa)電(dian)(dian)系(xi)(xi)統(tong)(tong)，由(you)于投資小、建設快、占地面(mian)積小、政策支(zhi)持力(li)度(du)大(da)等優點(dian)，是(shi)(shi)并網(wang)(wang)(wang)光(guang)伏(fu)發(fa)(fa)電(dian)(dian)的主流(liu)。

分布式光伏發電

分(fen)布式光伏發電(dian)(dian)系(xi)統，又稱分(fen)散式發電(dian)(dian)或分(fen)布式供(gong)能，是指在用(yong)戶現(xian)場或靠(kao)近用(yong)電(dian)(dian)現(xian)場配置(zhi)較小的(de)光伏發電(dian)(dian)供(gong)電(dian)(dian)系(xi)統，以(yi)滿足(zu)(zu)特(te)定(ding)用(yong)戶的(de)需求(qiu)，支持現(xian)存配電(dian)(dian)網的(de)經濟運行(xing)，或者同(tong)時滿足(zu)(zu)這兩個方(fang)面的(de)要(yao)求(qiu)。

　　分布式光伏(fu)發電(dian)(dian)系統的(de)基本設備包括光伏(fu)電(dian)(dian)池組件、光伏(fu)方陣支架、直流(liu)匯流(liu)箱、直流(liu)配(pei)電(dian)(dian)柜、并網(wang)逆(ni)變器、交流(liu)配(pei)電(dian)(dian)柜等設備，另外(wai)還有(you)供電(dian)(dian)系統監控(kong)裝置(zhi)和環(huan)境監測裝置(zhi)。其運行(xing)模式是在有(you)太陽(yang)輻射的(de)條件下，光伏(fu)發電(dian)(dian)系統的(de)太陽(yang)能電(dian)(dian)池組件陣列將太陽(yang)能轉換(huan)輸(shu)出的(de)電(dian)(dian)能，經(jing)過直流(liu)匯流(liu)箱集中送入(ru)直流(liu)配(pei)電(dian)(dian)柜，由并網(wang)逆(ni)變器逆(ni)變成交流(liu)電(dian)(dian)供給建筑自身負載，多余或不足(zu)的(de)電(dian)(dian)力通過聯接電(dian)(dian)網(wang)來調節。
