山東省青州市魯(lu)東機械(xie)2.1MW光(guang)伏發電(dian)(dian)站(zhan)項目。彩鋼瓦屋頂光(guang)伏發電(dian)(dian)站(zhan)，已(yi)并網發電(dian)(dian)成功！

輸送方式

太陽能光(guang)伏(fu)(fu)(fu)發(fa)電(dian)分為獨立光(guang)伏(fu)(fu)(fu)發(fa)電(dian)、并網光(guang)伏(fu)(fu)(fu)發(fa)電(dian)、分布式光(guang)伏(fu)(fu)(fu)發(fa)電(dian)

獨立光伏發電

獨立光(guang)伏發電系統(tong)也叫離網光(guang)伏發電系統(tong)。主(zhu)要(yao)由太陽能電池(chi)組件、控(kong)制器、蓄電池(chi)組成(cheng)，若要(yao)為(wei)交流負載供電，還需要(yao)配置(zhi)交流逆變(bian)器。

并網光伏發電

并(bing)(bing)網(wang)(wang)(wang)(wang)(wang)光(guang)伏發(fa)電(dian)(dian)(dian)(dian)系(xi)統就是(shi)(shi)太陽(yang)能組(zu)件(jian)產生(sheng)的(de)直流(liu)電(dian)(dian)(dian)(dian)經過并(bing)(bing)網(wang)(wang)(wang)(wang)(wang)逆變器轉換成(cheng)符合市電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)(wang)要求的(de)交流(liu)電(dian)(dian)(dian)(dian)之后直接接入公共電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)(wang)。并(bing)(bing)網(wang)(wang)(wang)(wang)(wang)光(guang)伏發(fa)電(dian)(dian)(dian)(dian)系(xi)統有集(ji)中式(shi)大(da)(da)(da)型并(bing)(bing)網(wang)(wang)(wang)(wang)(wang)光(guang)伏電(dian)(dian)(dian)(dian)站(zhan)一(yi)般(ban)都是(shi)(shi)國(guo)家級電(dian)(dian)(dian)(dian)站(zhan)，主要特點是(shi)(shi)將所(suo)發(fa)電(dian)(dian)(dian)(dian)能直接輸送到(dao)電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)(wang)，由電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)(wang)統一(yi)調配(pei)向用戶供(gong)電(dian)(dian)(dian)(dian)。但這(zhe)種電(dian)(dian)(dian)(dian)站(zhan)投資大(da)(da)(da)、建(jian)設(she)周期長、占地(di)面積大(da)(da)(da)，發(fa)展(zhan)難度(du)相對較大(da)(da)(da)。而分散式(shi)小(xiao)型并(bing)(bing)網(wang)(wang)(wang)(wang)(wang)光(guang)伏系(xi)統，特別是(shi)(shi)光(guang)伏建(jian)筑(zhu)一(yi)體(ti)化發(fa)電(dian)(dian)(dian)(dian)系(xi)統，由于投資小(xiao)、建(jian)設(she)快、占地(di)面積小(xiao)、政(zheng)策支持力度(du)大(da)(da)(da)等優點，是(shi)(shi)并(bing)(bing)網(wang)(wang)(wang)(wang)(wang)光(guang)伏發(fa)電(dian)(dian)(dian)(dian)的(de)主流(liu)。

分布式光伏發電

分(fen)布(bu)(bu)式光伏發(fa)電系(xi)統(tong)，又稱(cheng)分(fen)散式發(fa)電或分(fen)布(bu)(bu)式供(gong)能，是指在用戶(hu)現場或靠近用電現場配置較小的光伏發(fa)電供(gong)電系(xi)統(tong)，以(yi)滿足特定用戶(hu)的需求，支持現存配電網的經(jing)濟運行，或者同時滿足這兩個方面的要求。

　　分布式光伏發電系統的基(ji)本(ben)設備包(bao)括光伏電池組(zu)件(jian)、光伏方陣(zhen)支架、直(zhi)流(liu)匯流(liu)箱、直(zhi)流(liu)配(pei)(pei)電柜(ju)、并(bing)網(wang)逆(ni)變(bian)(bian)器、交流(liu)配(pei)(pei)電柜(ju)等設備，另外還有供(gong)電系統監控裝置(zhi)和環境(jing)監測(ce)裝置(zhi)。其(qi)運行模式是在(zai)有太陽輻射的條(tiao)件(jian)下(xia)，光伏發電系統的太陽能電池組(zu)件(jian)陣(zhen)列(lie)將(jiang)太陽能轉換輸出的電能，經過直(zhi)流(liu)匯流(liu)箱集(ji)中送入(ru)直(zhi)流(liu)配(pei)(pei)電柜(ju)，由(you)并(bing)網(wang)逆(ni)變(bian)(bian)器逆(ni)變(bian)(bian)成交流(liu)電供(gong)給建筑自身(shen)負載，多余(yu)或(huo)不足的電力通過聯接電網(wang)來調節(jie)。
