山(shan)東省青州市魯東機械2.1MW光(guang)伏發(fa)(fa)電(dian)站項目。彩鋼(gang)瓦屋頂光(guang)伏發(fa)(fa)電(dian)站，已并網發(fa)(fa)電(dian)成功！

輸送方式

太(tai)陽能光伏發(fa)(fa)電分(fen)為(wei)獨立光伏發(fa)(fa)電、并(bing)網光伏發(fa)(fa)電、分(fen)布(bu)式光伏發(fa)(fa)電

獨立光伏發電

獨立光伏發(fa)電(dian)(dian)系(xi)統(tong)也叫離(li)網光伏發(fa)電(dian)(dian)系(xi)統(tong)。主要(yao)由太(tai)陽(yang)能電(dian)(dian)池組(zu)件、控(kong)制器、蓄電(dian)(dian)池組(zu)成，若要(yao)為交流負載供電(dian)(dian)，還需要(yao)配(pei)置(zhi)交流逆(ni)變器。

并網光伏發電

并(bing)(bing)網(wang)光(guang)伏(fu)(fu)發電(dian)(dian)系(xi)統(tong)就是太陽能組(zu)件產生的(de)直流電(dian)(dian)經過并(bing)(bing)網(wang)逆變器轉換成符(fu)合市電(dian)(dian)電(dian)(dian)網(wang)要求的(de)交流電(dian)(dian)之后直接(jie)(jie)接(jie)(jie)入公共電(dian)(dian)網(wang)。并(bing)(bing)網(wang)光(guang)伏(fu)(fu)發電(dian)(dian)系(xi)統(tong)有(you)集中式大型(xing)并(bing)(bing)網(wang)光(guang)伏(fu)(fu)電(dian)(dian)站一(yi)般都是國家級(ji)電(dian)(dian)站，主要特點(dian)(dian)是將(jiang)所(suo)發電(dian)(dian)能直接(jie)(jie)輸送到(dao)電(dian)(dian)網(wang)，由(you)電(dian)(dian)網(wang)統(tong)一(yi)調配向用(yong)戶(hu)供(gong)電(dian)(dian)。但這種電(dian)(dian)站投資大、建設周期長、占(zhan)地(di)面積大，發展難度(du)相對較大。而分散式小型(xing)并(bing)(bing)網(wang)光(guang)伏(fu)(fu)系(xi)統(tong)，特別是光(guang)伏(fu)(fu)建筑一(yi)體化(hua)發電(dian)(dian)系(xi)統(tong)，由(you)于投資小、建設快、占(zhan)地(di)面積小、政策(ce)支(zhi)持力(li)度(du)大等優點(dian)(dian)，是并(bing)(bing)網(wang)光(guang)伏(fu)(fu)發電(dian)(dian)的(de)主流。

分布式光伏發電

分布式光伏發電(dian)(dian)系統，又稱(cheng)分散式發電(dian)(dian)或分布式供(gong)能，是指在(zai)用(yong)(yong)戶現場或靠近(jin)用(yong)(yong)電(dian)(dian)現場配置較小的(de)光伏發電(dian)(dian)供(gong)電(dian)(dian)系統，以滿(man)足特定用(yong)(yong)戶的(de)需求，支持現存配電(dian)(dian)網的(de)經濟運行，或者同時滿(man)足這兩個(ge)方面的(de)要求。

　　分布式光(guang)伏(fu)(fu)發電(dian)系統(tong)的基本設備(bei)包括光(guang)伏(fu)(fu)電(dian)池(chi)(chi)組件、光(guang)伏(fu)(fu)方陣(zhen)支架、直(zhi)(zhi)流匯(hui)流箱、直(zhi)(zhi)流配電(dian)柜(ju)、并(bing)網(wang)逆(ni)(ni)變器、交流配電(dian)柜(ju)等設備(bei)，另外還有供(gong)電(dian)系統(tong)監控(kong)裝置(zhi)和環境監測裝置(zhi)。其運(yun)行模式是在(zai)有太(tai)陽(yang)輻射的條件下，光(guang)伏(fu)(fu)發電(dian)系統(tong)的太(tai)陽(yang)能電(dian)池(chi)(chi)組件陣(zhen)列(lie)將太(tai)陽(yang)能轉換輸(shu)出的電(dian)能，經過直(zhi)(zhi)流匯(hui)流箱集中送入直(zhi)(zhi)流配電(dian)柜(ju)，由(you)并(bing)網(wang)逆(ni)(ni)變器逆(ni)(ni)變成交流電(dian)供(gong)給建筑自身負載，多余(yu)或不足(zu)的電(dian)力通(tong)過聯接電(dian)網(wang)來調節。
