山(shan)東省(sheng)青(qing)州(zhou)市魯東機械2.1MW光(guang)伏(fu)發電站項(xiang)目。彩鋼瓦屋頂光(guang)伏(fu)發電站，已并網發電成功！

輸送方式

太陽能光伏(fu)(fu)發電分為獨立(li)光伏(fu)(fu)發電、并網光伏(fu)(fu)發電、分布式(shi)光伏(fu)(fu)發電

獨立光伏發電

獨立(li)光伏發電系(xi)統(tong)(tong)也叫離網光伏發電系(xi)統(tong)(tong)。主要由太陽能電池組(zu)件(jian)、控制器、蓄電池組(zu)成，若要為交(jiao)流(liu)負載供(gong)電，還(huan)需(xu)要配(pei)置交(jiao)流(liu)逆變器。

并網光伏發電

并網(wang)(wang)(wang)光(guang)(guang)(guang)(guang)伏(fu)(fu)(fu)發(fa)(fa)電(dian)(dian)系(xi)統(tong)(tong)就(jiu)是(shi)太陽能組件產生的(de)直(zhi)流電(dian)(dian)經(jing)過并網(wang)(wang)(wang)逆變器轉換成符合市電(dian)(dian)電(dian)(dian)網(wang)(wang)(wang)要(yao)求(qiu)的(de)交(jiao)流電(dian)(dian)之后(hou)直(zhi)接(jie)接(jie)入公共(gong)電(dian)(dian)網(wang)(wang)(wang)。并網(wang)(wang)(wang)光(guang)(guang)(guang)(guang)伏(fu)(fu)(fu)發(fa)(fa)電(dian)(dian)系(xi)統(tong)(tong)有集中式(shi)大(da)(da)(da)型并網(wang)(wang)(wang)光(guang)(guang)(guang)(guang)伏(fu)(fu)(fu)電(dian)(dian)站一(yi)般都是(shi)國家級電(dian)(dian)站，主要(yao)特點是(shi)將(jiang)所發(fa)(fa)電(dian)(dian)能直(zhi)接(jie)輸送(song)到(dao)電(dian)(dian)網(wang)(wang)(wang)，由電(dian)(dian)網(wang)(wang)(wang)統(tong)(tong)一(yi)調配向用戶供電(dian)(dian)。但(dan)這種(zhong)電(dian)(dian)站投(tou)資大(da)(da)(da)、建(jian)設(she)周期長、占地面積大(da)(da)(da)，發(fa)(fa)展難度相對較大(da)(da)(da)。而分散(san)式(shi)小(xiao)型并網(wang)(wang)(wang)光(guang)(guang)(guang)(guang)伏(fu)(fu)(fu)系(xi)統(tong)(tong)，特別是(shi)光(guang)(guang)(guang)(guang)伏(fu)(fu)(fu)建(jian)筑一(yi)體(ti)化發(fa)(fa)電(dian)(dian)系(xi)統(tong)(tong)，由于投(tou)資小(xiao)、建(jian)設(she)快、占地面積小(xiao)、政(zheng)策支持力度大(da)(da)(da)等優點，是(shi)并網(wang)(wang)(wang)光(guang)(guang)(guang)(guang)伏(fu)(fu)(fu)發(fa)(fa)電(dian)(dian)的(de)主流。

分布式光伏發電

分布式光(guang)伏發(fa)電(dian)系統(tong)，又稱分散式發(fa)電(dian)或(huo)分布式供能，是(shi)指(zhi)在(zai)用(yong)戶(hu)現場(chang)或(huo)靠近用(yong)電(dian)現場(chang)配置較小的(de)光(guang)伏發(fa)電(dian)供電(dian)系統(tong)，以(yi)滿足(zu)特定用(yong)戶(hu)的(de)需求，支持(chi)現存(cun)配電(dian)網的(de)經濟(ji)運行，或(huo)者同(tong)時滿足(zu)這兩(liang)個(ge)方面的(de)要求。

　　分布式光伏(fu)發(fa)電(dian)系統的(de)(de)基本設(she)備包括光伏(fu)電(dian)池組件、光伏(fu)方陣(zhen)支架(jia)、直(zhi)流(liu)匯流(liu)箱、直(zhi)流(liu)配(pei)電(dian)柜(ju)(ju)、并網逆(ni)(ni)變器(qi)、交(jiao)(jiao)流(liu)配(pei)電(dian)柜(ju)(ju)等設(she)備，另外(wai)還有(you)供電(dian)系統監控裝(zhuang)(zhuang)置和環境監測裝(zhuang)(zhuang)置。其運行模式是在有(you)太陽(yang)輻射的(de)(de)條(tiao)件下，光伏(fu)發(fa)電(dian)系統的(de)(de)太陽(yang)能電(dian)池組件陣(zhen)列將太陽(yang)能轉(zhuan)換輸出的(de)(de)電(dian)能，經(jing)過直(zhi)流(liu)匯流(liu)箱集中送入直(zhi)流(liu)配(pei)電(dian)柜(ju)(ju)，由并網逆(ni)(ni)變器(qi)逆(ni)(ni)變成交(jiao)(jiao)流(liu)電(dian)供給建筑(zhu)自身負載，多余或(huo)不足的(de)(de)電(dian)力通過聯(lian)接電(dian)網來調節(jie)。
