山東省青州(zhou)市魯東機械2.1MW光伏發(fa)電站(zhan)項(xiang)目。彩鋼瓦屋(wu)頂光伏發(fa)電站(zhan)，已并(bing)網(wang)發(fa)電成功！

輸送方式

太陽能(neng)光(guang)(guang)(guang)伏發電(dian)分為獨(du)立光(guang)(guang)(guang)伏發電(dian)、并網光(guang)(guang)(guang)伏發電(dian)、分布式(shi)光(guang)(guang)(guang)伏發電(dian)

獨立光伏發電

獨(du)立光伏發電(dian)系統(tong)也叫離(li)網光伏發電(dian)系統(tong)。主要(yao)由太陽能電(dian)池組件、控(kong)制器、蓄電(dian)池組成，若(ruo)要(yao)為交流負載供電(dian)，還需要(yao)配置交流逆變器。

并網光伏發電

并(bing)網(wang)光(guang)(guang)伏(fu)發(fa)(fa)電(dian)(dian)(dian)系統就是(shi)(shi)太陽能組件(jian)產生的(de)直(zhi)(zhi)流電(dian)(dian)(dian)經(jing)過并(bing)網(wang)逆變器轉換成符合市電(dian)(dian)(dian)電(dian)(dian)(dian)網(wang)要(yao)求(qiu)的(de)交流電(dian)(dian)(dian)之(zhi)后直(zhi)(zhi)接接入公共電(dian)(dian)(dian)網(wang)。并(bing)網(wang)光(guang)(guang)伏(fu)發(fa)(fa)電(dian)(dian)(dian)系統有集中式(shi)大(da)型并(bing)網(wang)光(guang)(guang)伏(fu)電(dian)(dian)(dian)站(zhan)一(yi)般(ban)都是(shi)(shi)國家級電(dian)(dian)(dian)站(zhan)，主(zhu)要(yao)特點是(shi)(shi)將(jiang)所發(fa)(fa)電(dian)(dian)(dian)能直(zhi)(zhi)接輸送(song)到電(dian)(dian)(dian)網(wang)，由電(dian)(dian)(dian)網(wang)統一(yi)調配向用戶供(gong)電(dian)(dian)(dian)。但這種(zhong)電(dian)(dian)(dian)站(zhan)投(tou)資大(da)、建(jian)設(she)周期長、占地面積大(da)，發(fa)(fa)展(zhan)難(nan)度相對較大(da)。而(er)分散式(shi)小(xiao)型并(bing)網(wang)光(guang)(guang)伏(fu)系統，特別是(shi)(shi)光(guang)(guang)伏(fu)建(jian)筑一(yi)體(ti)化(hua)發(fa)(fa)電(dian)(dian)(dian)系統，由于投(tou)資小(xiao)、建(jian)設(she)快、占地面積小(xiao)、政策支(zhi)持力度大(da)等(deng)優點，是(shi)(shi)并(bing)網(wang)光(guang)(guang)伏(fu)發(fa)(fa)電(dian)(dian)(dian)的(de)主(zhu)流。

分布式光伏發電

分布(bu)式(shi)光伏發(fa)電(dian)(dian)(dian)系統，又稱分散式(shi)發(fa)電(dian)(dian)(dian)或分布(bu)式(shi)供(gong)能，是指在用戶(hu)現(xian)場(chang)或靠近用電(dian)(dian)(dian)現(xian)場(chang)配置較(jiao)小的(de)光伏發(fa)電(dian)(dian)(dian)供(gong)電(dian)(dian)(dian)系統，以滿足特定用戶(hu)的(de)需(xu)求(qiu)，支持現(xian)存配電(dian)(dian)(dian)網的(de)經濟運行，或者(zhe)同(tong)時滿足這兩(liang)個方面(mian)的(de)要(yao)求(qiu)。

　　分布式(shi)光(guang)(guang)伏發(fa)電(dian)(dian)(dian)系統(tong)的基本設(she)備包括光(guang)(guang)伏電(dian)(dian)(dian)池(chi)組件、光(guang)(guang)伏方陣支(zhi)架(jia)、直流(liu)匯(hui)流(liu)箱、直流(liu)配(pei)電(dian)(dian)(dian)柜、并網逆變(bian)器、交(jiao)(jiao)流(liu)配(pei)電(dian)(dian)(dian)柜等(deng)設(she)備，另(ling)外還有供(gong)電(dian)(dian)(dian)系統(tong)監控裝置和(he)環境監測裝置。其運(yun)行模式(shi)是在有太陽輻射的條件下，光(guang)(guang)伏發(fa)電(dian)(dian)(dian)系統(tong)的太陽能電(dian)(dian)(dian)池(chi)組件陣列將太陽能轉換輸出的電(dian)(dian)(dian)能，經(jing)過直流(liu)匯(hui)流(liu)箱集(ji)中送入直流(liu)配(pei)電(dian)(dian)(dian)柜，由并網逆變(bian)器逆變(bian)成交(jiao)(jiao)流(liu)電(dian)(dian)(dian)供(gong)給(gei)建筑自身負載，多(duo)余或不足的電(dian)(dian)(dian)力通過聯接(jie)電(dian)(dian)(dian)網來調節。
