山(shan)東(dong)省青州市魯東(dong)機械2.1MW光(guang)伏發電(dian)站項目(mu)。彩(cai)鋼瓦屋頂光(guang)伏發電(dian)站，已并網發電(dian)成功(gong)！

輸送方式

太陽能(neng)光(guang)伏發電(dian)分為獨立光(guang)伏發電(dian)、并(bing)網(wang)光(guang)伏發電(dian)、分布式光(guang)伏發電(dian)

獨立光伏發電

獨立光伏(fu)發電系統也叫離(li)網光伏(fu)發電系統。主要(yao)由太(tai)陽能電池(chi)組件、控制器、蓄(xu)電池(chi)組成(cheng)，若要(yao)為交(jiao)流(liu)負載供電，還需要(yao)配置交(jiao)流(liu)逆變器。

并網光伏發電

并(bing)(bing)網(wang)(wang)光伏(fu)發(fa)電(dian)(dian)(dian)系(xi)(xi)(xi)統(tong)就是(shi)太陽能(neng)組件產生的直流電(dian)(dian)(dian)經過并(bing)(bing)網(wang)(wang)逆變(bian)器轉換(huan)成符合(he)市電(dian)(dian)(dian)電(dian)(dian)(dian)網(wang)(wang)要求的交(jiao)流電(dian)(dian)(dian)之后直接(jie)(jie)接(jie)(jie)入公共電(dian)(dian)(dian)網(wang)(wang)。并(bing)(bing)網(wang)(wang)光伏(fu)發(fa)電(dian)(dian)(dian)系(xi)(xi)(xi)統(tong)有集中式大型并(bing)(bing)網(wang)(wang)光伏(fu)電(dian)(dian)(dian)站(zhan)(zhan)一(yi)般都(dou)是(shi)國家級(ji)電(dian)(dian)(dian)站(zhan)(zhan)，主(zhu)要特(te)點是(shi)將(jiang)所發(fa)電(dian)(dian)(dian)能(neng)直接(jie)(jie)輸送到電(dian)(dian)(dian)網(wang)(wang)，由電(dian)(dian)(dian)網(wang)(wang)統(tong)一(yi)調配(pei)向(xiang)用(yong)戶供(gong)電(dian)(dian)(dian)。但這種(zhong)電(dian)(dian)(dian)站(zhan)(zhan)投資大、建設周(zhou)期長、占(zhan)地面積大，發(fa)展(zhan)難度相對較大。而分散式小(xiao)(xiao)型并(bing)(bing)網(wang)(wang)光伏(fu)系(xi)(xi)(xi)統(tong)，特(te)別(bie)是(shi)光伏(fu)建筑一(yi)體化發(fa)電(dian)(dian)(dian)系(xi)(xi)(xi)統(tong)，由于投資小(xiao)(xiao)、建設快、占(zhan)地面積小(xiao)(xiao)、政策支持力度大等優點，是(shi)并(bing)(bing)網(wang)(wang)光伏(fu)發(fa)電(dian)(dian)(dian)的主(zhu)流。

分布式光伏發電

分布式(shi)光伏發(fa)電(dian)系(xi)統，又稱分散式(shi)發(fa)電(dian)或分布式(shi)供能(neng)，是指在用戶(hu)(hu)現(xian)(xian)場(chang)或靠(kao)近用電(dian)現(xian)(xian)場(chang)配(pei)置較小的(de)光伏發(fa)電(dian)供電(dian)系(xi)統，以滿足特定用戶(hu)(hu)的(de)需(xu)求(qiu)，支持現(xian)(xian)存配(pei)電(dian)網的(de)經(jing)濟運(yun)行(xing)，或者(zhe)同時滿足這兩個方面的(de)要求(qiu)。

　　分(fen)布(bu)式光伏(fu)發電(dian)(dian)系(xi)統的基本設備(bei)包括光伏(fu)電(dian)(dian)池(chi)(chi)組件、光伏(fu)方陣支(zhi)架、直(zhi)流匯(hui)流箱(xiang)、直(zhi)流配電(dian)(dian)柜(ju)(ju)、并網(wang)(wang)(wang)逆變(bian)器、交流配電(dian)(dian)柜(ju)(ju)等設備(bei)，另(ling)外還有供(gong)電(dian)(dian)系(xi)統監控裝置(zhi)和環境(jing)監測裝置(zhi)。其運(yun)行模(mo)式是在(zai)有太(tai)陽(yang)輻射的條件下，光伏(fu)發電(dian)(dian)系(xi)統的太(tai)陽(yang)能(neng)電(dian)(dian)池(chi)(chi)組件陣列(lie)將太(tai)陽(yang)能(neng)轉換輸出的電(dian)(dian)能(neng)，經過(guo)直(zhi)流匯(hui)流箱(xiang)集中送(song)入直(zhi)流配電(dian)(dian)柜(ju)(ju)，由并網(wang)(wang)(wang)逆變(bian)器逆變(bian)成(cheng)交流電(dian)(dian)供(gong)給(gei)建筑自身(shen)負載，多余或不(bu)足的電(dian)(dian)力通過(guo)聯接電(dian)(dian)網(wang)(wang)(wang)來調節。
