山東省青州市(shi)魯東機(ji)械2.1MW光(guang)伏發(fa)(fa)電站項目。彩鋼瓦屋頂光(guang)伏發(fa)(fa)電站，已并網發(fa)(fa)電成功！

輸送方式

太(tai)陽能光(guang)(guang)(guang)伏發(fa)(fa)(fa)電分(fen)為(wei)獨立(li)光(guang)(guang)(guang)伏發(fa)(fa)(fa)電、并網光(guang)(guang)(guang)伏發(fa)(fa)(fa)電、分(fen)布(bu)式光(guang)(guang)(guang)伏發(fa)(fa)(fa)電

獨立光伏發電

獨立光(guang)伏發電系統也叫離(li)網光(guang)伏發電系統。主要(yao)由太(tai)陽能電池組件、控制器、蓄電池組成，若要(yao)為(wei)交流負載供電，還需要(yao)配置(zhi)交流逆(ni)變器。

并網光伏發電

并網(wang)光(guang)伏(fu)發(fa)電(dian)(dian)系(xi)統(tong)就是(shi)(shi)太陽(yang)能(neng)組件(jian)產生的(de)(de)直(zhi)流電(dian)(dian)經過并網(wang)逆變器(qi)轉換成符合市電(dian)(dian)電(dian)(dian)網(wang)要求的(de)(de)交流電(dian)(dian)之后直(zhi)接(jie)(jie)接(jie)(jie)入公共電(dian)(dian)網(wang)。并網(wang)光(guang)伏(fu)發(fa)電(dian)(dian)系(xi)統(tong)有集(ji)中式大(da)型并網(wang)光(guang)伏(fu)電(dian)(dian)站一(yi)般都是(shi)(shi)國家級電(dian)(dian)站，主要特(te)點是(shi)(shi)將所發(fa)電(dian)(dian)能(neng)直(zhi)接(jie)(jie)輸送到電(dian)(dian)網(wang)，由電(dian)(dian)網(wang)統(tong)一(yi)調配向用戶供(gong)電(dian)(dian)。但這種(zhong)電(dian)(dian)站投(tou)資大(da)、建設(she)周期長、占(zhan)地面(mian)(mian)積大(da)，發(fa)展(zhan)難度(du)(du)相對較大(da)。而分散式小型并網(wang)光(guang)伏(fu)系(xi)統(tong)，特(te)別是(shi)(shi)光(guang)伏(fu)建筑一(yi)體(ti)化發(fa)電(dian)(dian)系(xi)統(tong)，由于投(tou)資小、建設(she)快、占(zhan)地面(mian)(mian)積小、政策支(zhi)持力度(du)(du)大(da)等優點，是(shi)(shi)并網(wang)光(guang)伏(fu)發(fa)電(dian)(dian)的(de)(de)主流。

分布式光伏發電

分(fen)布式光伏(fu)發(fa)(fa)電(dian)系統，又稱分(fen)散式發(fa)(fa)電(dian)或(huo)分(fen)布式供(gong)能，是指在用(yong)戶現(xian)場或(huo)靠近用(yong)電(dian)現(xian)場配置較小的(de)(de)光伏(fu)發(fa)(fa)電(dian)供(gong)電(dian)系統，以滿足(zu)特定用(yong)戶的(de)(de)需求(qiu)(qiu)，支(zhi)持現(xian)存配電(dian)網的(de)(de)經濟(ji)運(yun)行(xing)，或(huo)者(zhe)同時滿足(zu)這兩個(ge)方面的(de)(de)要求(qiu)(qiu)。

　　分布(bu)式光(guang)伏(fu)發電(dian)(dian)(dian)系統的(de)基本設備包括光(guang)伏(fu)電(dian)(dian)(dian)池(chi)組件(jian)、光(guang)伏(fu)方陣(zhen)支架、直(zhi)(zhi)流(liu)匯流(liu)箱(xiang)、直(zhi)(zhi)流(liu)配電(dian)(dian)(dian)柜、并(bing)網(wang)逆(ni)變器、交(jiao)流(liu)配電(dian)(dian)(dian)柜等設備，另外還(huan)有供電(dian)(dian)(dian)系統監(jian)控裝置(zhi)和環境監(jian)測裝置(zhi)。其運行模式是在(zai)有太陽輻射的(de)條件(jian)下，光(guang)伏(fu)發電(dian)(dian)(dian)系統的(de)太陽能(neng)電(dian)(dian)(dian)池(chi)組件(jian)陣(zhen)列將太陽能(neng)轉換輸出的(de)電(dian)(dian)(dian)能(neng)，經(jing)過直(zhi)(zhi)流(liu)匯流(liu)箱(xiang)集(ji)中送入直(zhi)(zhi)流(liu)配電(dian)(dian)(dian)柜，由并(bing)網(wang)逆(ni)變器逆(ni)變成交(jiao)流(liu)電(dian)(dian)(dian)供給建筑自身負載，多(duo)余或不足(zu)的(de)電(dian)(dian)(dian)力通(tong)過聯(lian)接電(dian)(dian)(dian)網(wang)來調節。
