山東省(sheng)青(qing)州市魯東機械(xie)2.1MW光(guang)(guang)伏(fu)發(fa)(fa)電站項目(mu)。彩鋼瓦屋(wu)頂(ding)光(guang)(guang)伏(fu)發(fa)(fa)電站，已并網發(fa)(fa)電成功！

輸送方式

太陽能光(guang)伏發(fa)電分為(wei)獨立光(guang)伏發(fa)電、并網光(guang)伏發(fa)電、分布式光(guang)伏發(fa)電

獨立光伏發電

獨立(li)光(guang)伏(fu)發電(dian)系統也叫離網(wang)光(guang)伏(fu)發電(dian)系統。主要由太陽(yang)能(neng)電(dian)池組件、控制器、蓄電(dian)池組成(cheng)，若要為交流(liu)負載供電(dian)，還(huan)需要配(pei)置(zhi)交流(liu)逆變器。

并網光伏發電

并網(wang)(wang)光(guang)伏發(fa)(fa)電(dian)(dian)(dian)(dian)系(xi)統(tong)就是(shi)太陽能組件產生的直流電(dian)(dian)(dian)(dian)經(jing)過并網(wang)(wang)逆變器轉(zhuan)換(huan)成符(fu)合市電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)網(wang)(wang)要求(qiu)的交流電(dian)(dian)(dian)(dian)之后直接接入公共電(dian)(dian)(dian)(dian)網(wang)(wang)。并網(wang)(wang)光(guang)伏發(fa)(fa)電(dian)(dian)(dian)(dian)系(xi)統(tong)有集中式大(da)型(xing)并網(wang)(wang)光(guang)伏電(dian)(dian)(dian)(dian)站一(yi)般(ban)都是(shi)國家級電(dian)(dian)(dian)(dian)站，主要特點是(shi)將所發(fa)(fa)電(dian)(dian)(dian)(dian)能直接輸送到電(dian)(dian)(dian)(dian)網(wang)(wang)，由電(dian)(dian)(dian)(dian)網(wang)(wang)統(tong)一(yi)調配向用(yong)戶供(gong)電(dian)(dian)(dian)(dian)。但這種電(dian)(dian)(dian)(dian)站投(tou)資(zi)大(da)、建(jian)設周期長(chang)、占地(di)面(mian)積大(da)，發(fa)(fa)展難度相對較大(da)。而(er)分散式小型(xing)并網(wang)(wang)光(guang)伏系(xi)統(tong)，特別是(shi)光(guang)伏建(jian)筑一(yi)體化發(fa)(fa)電(dian)(dian)(dian)(dian)系(xi)統(tong)，由于(yu)投(tou)資(zi)小、建(jian)設快、占地(di)面(mian)積小、政策支(zhi)持(chi)力度大(da)等(deng)優點，是(shi)并網(wang)(wang)光(guang)伏發(fa)(fa)電(dian)(dian)(dian)(dian)的主流。

分布式光伏發電

分布(bu)式光伏發電(dian)系統(tong)，又稱分散(san)式發電(dian)或分布(bu)式供能，是指在(zai)用戶現(xian)場或靠近用電(dian)現(xian)場配置較小的光伏發電(dian)供電(dian)系統(tong)，以滿足特(te)定用戶的需求，支持現(xian)存配電(dian)網的經濟運行，或者(zhe)同時滿足這(zhe)兩個方面的要(yao)求。

　　分布(bu)式(shi)光(guang)伏(fu)發(fa)電系(xi)統(tong)的(de)(de)基本設備(bei)包括光(guang)伏(fu)電池(chi)(chi)組件(jian)、光(guang)伏(fu)方陣支架、直(zhi)流匯流箱、直(zhi)流配電柜(ju)、并網逆變(bian)器(qi)、交(jiao)流配電柜(ju)等設備(bei)，另外還有供電系(xi)統(tong)監控裝(zhuang)置和(he)環(huan)境監測裝(zhuang)置。其運行模式(shi)是在有太陽輻射的(de)(de)條件(jian)下，光(guang)伏(fu)發(fa)電系(xi)統(tong)的(de)(de)太陽能(neng)電池(chi)(chi)組件(jian)陣列將太陽能(neng)轉換輸出的(de)(de)電能(neng)，經過直(zhi)流匯流箱集中送入直(zhi)流配電柜(ju)，由并網逆變(bian)器(qi)逆變(bian)成交(jiao)流電供給建筑自身負(fu)載(zai)，多余(yu)或不足的(de)(de)電力通過聯接(jie)電網來調(diao)節。
