山(shan)東省青州市魯東機械2.1MW光伏(fu)發電站項(xiang)目。彩鋼瓦屋頂光伏(fu)發電站，已并網發電成功！

輸送方式

太(tai)陽能光(guang)伏(fu)發(fa)電(dian)分為獨立光(guang)伏(fu)發(fa)電(dian)、并網光(guang)伏(fu)發(fa)電(dian)、分布(bu)式(shi)光(guang)伏(fu)發(fa)電(dian)

獨立光伏發電

獨立光(guang)伏發電(dian)系統(tong)也叫離網光(guang)伏發電(dian)系統(tong)。主要由太陽能電(dian)池組件、控制器、蓄電(dian)池組成，若要為(wei)交流(liu)(liu)負(fu)載供電(dian)，還需(xu)要配(pei)置交流(liu)(liu)逆變(bian)器。

并網光伏發電

并網(wang)(wang)(wang)光(guang)伏(fu)發(fa)(fa)電(dian)(dian)(dian)系(xi)統(tong)就是太(tai)陽能(neng)組件產生的(de)直(zhi)(zhi)(zhi)流(liu)電(dian)(dian)(dian)經過并網(wang)(wang)(wang)逆變器轉換成符合市(shi)電(dian)(dian)(dian)電(dian)(dian)(dian)網(wang)(wang)(wang)要求的(de)交流(liu)電(dian)(dian)(dian)之后直(zhi)(zhi)(zhi)接接入公共電(dian)(dian)(dian)網(wang)(wang)(wang)。并網(wang)(wang)(wang)光(guang)伏(fu)發(fa)(fa)電(dian)(dian)(dian)系(xi)統(tong)有(you)集中(zhong)式大(da)型并網(wang)(wang)(wang)光(guang)伏(fu)電(dian)(dian)(dian)站(zhan)(zhan)一(yi)(yi)般都是國(guo)家級電(dian)(dian)(dian)站(zhan)(zhan)，主(zhu)要特點(dian)是將所發(fa)(fa)電(dian)(dian)(dian)能(neng)直(zhi)(zhi)(zhi)接輸(shu)送(song)到(dao)電(dian)(dian)(dian)網(wang)(wang)(wang)，由(you)電(dian)(dian)(dian)網(wang)(wang)(wang)統(tong)一(yi)(yi)調配向用戶(hu)供電(dian)(dian)(dian)。但這種電(dian)(dian)(dian)站(zhan)(zhan)投(tou)資大(da)、建(jian)(jian)設(she)周期(qi)長、占地面積(ji)大(da)，發(fa)(fa)展(zhan)難度相對較大(da)。而分散式小(xiao)型并網(wang)(wang)(wang)光(guang)伏(fu)系(xi)統(tong)，特別是光(guang)伏(fu)建(jian)(jian)筑一(yi)(yi)體化發(fa)(fa)電(dian)(dian)(dian)系(xi)統(tong)，由(you)于投(tou)資小(xiao)、建(jian)(jian)設(she)快、占地面積(ji)小(xiao)、政策支持力度大(da)等優點(dian)，是并網(wang)(wang)(wang)光(guang)伏(fu)發(fa)(fa)電(dian)(dian)(dian)的(de)主(zhu)流(liu)。

分布式光伏發電

分(fen)布式(shi)光伏(fu)發電系統，又稱分(fen)散(san)式(shi)發電或分(fen)布式(shi)供(gong)能，是指在用(yong)(yong)戶(hu)現場或靠近(jin)用(yong)(yong)電現場配(pei)置較小的(de)光伏(fu)發電供(gong)電系統，以(yi)滿足特(te)定用(yong)(yong)戶(hu)的(de)需求(qiu)，支持現存配(pei)電網的(de)經濟運行，或者同時滿足這(zhe)兩(liang)個方(fang)面的(de)要求(qiu)。

　　分布式光(guang)(guang)伏(fu)發(fa)(fa)電(dian)(dian)系統(tong)(tong)的(de)基本(ben)設備包括(kuo)光(guang)(guang)伏(fu)電(dian)(dian)池組件、光(guang)(guang)伏(fu)方陣支(zhi)架、直(zhi)(zhi)流(liu)(liu)匯(hui)流(liu)(liu)箱、直(zhi)(zhi)流(liu)(liu)配(pei)電(dian)(dian)柜(ju)、并網逆(ni)變(bian)器(qi)、交流(liu)(liu)配(pei)電(dian)(dian)柜(ju)等(deng)設備，另外(wai)還有供電(dian)(dian)系統(tong)(tong)監控裝置(zhi)和(he)環(huan)境監測裝置(zhi)。其運(yun)行模(mo)式是在有太(tai)(tai)陽輻射的(de)條件下，光(guang)(guang)伏(fu)發(fa)(fa)電(dian)(dian)系統(tong)(tong)的(de)太(tai)(tai)陽能(neng)電(dian)(dian)池組件陣列將太(tai)(tai)陽能(neng)轉換輸(shu)出的(de)電(dian)(dian)能(neng)，經過直(zhi)(zhi)流(liu)(liu)匯(hui)流(liu)(liu)箱集中送入(ru)直(zhi)(zhi)流(liu)(liu)配(pei)電(dian)(dian)柜(ju)，由并網逆(ni)變(bian)器(qi)逆(ni)變(bian)成(cheng)交流(liu)(liu)電(dian)(dian)供給建筑自(zi)身負(fu)載，多余或不足的(de)電(dian)(dian)力通過聯接電(dian)(dian)網來(lai)調節。
