山東省(sheng)青州(zhou)市魯東機械2.1MW光(guang)伏發(fa)電(dian)(dian)站項(xiang)目。彩鋼瓦屋頂光(guang)伏發(fa)電(dian)(dian)站，已并網發(fa)電(dian)(dian)成功！

輸送方式

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

獨立光伏發電

獨立(li)光(guang)伏(fu)發電(dian)系統也叫(jiao)離網光(guang)伏(fu)發電(dian)系統。主(zhu)要(yao)由太陽能電(dian)池(chi)組件、控(kong)制(zhi)器(qi)、蓄電(dian)池(chi)組成，若要(yao)為交流負(fu)載供電(dian)，還(huan)需要(yao)配置交流逆(ni)變器(qi)。

并網光伏發電

并(bing)(bing)(bing)網(wang)(wang)光(guang)伏發(fa)電(dian)(dian)系(xi)(xi)統(tong)就是(shi)太陽能組(zu)件(jian)產生的直流電(dian)(dian)經過(guo)并(bing)(bing)(bing)網(wang)(wang)逆變器轉換成符合市電(dian)(dian)電(dian)(dian)網(wang)(wang)要(yao)求的交流電(dian)(dian)之后直接接入(ru)公共電(dian)(dian)網(wang)(wang)。并(bing)(bing)(bing)網(wang)(wang)光(guang)伏發(fa)電(dian)(dian)系(xi)(xi)統(tong)有集中式大型(xing)并(bing)(bing)(bing)網(wang)(wang)光(guang)伏電(dian)(dian)站一(yi)般都是(shi)國家級電(dian)(dian)站，主要(yao)特點(dian)是(shi)將所(suo)發(fa)電(dian)(dian)能直接輸(shu)送到(dao)電(dian)(dian)網(wang)(wang)，由(you)(you)電(dian)(dian)網(wang)(wang)統(tong)一(yi)調配(pei)向用戶供電(dian)(dian)。但這種電(dian)(dian)站投資大、建設周期長、占地(di)面積大，發(fa)展難度相(xiang)對較大。而分散式小型(xing)并(bing)(bing)(bing)網(wang)(wang)光(guang)伏系(xi)(xi)統(tong)，特別是(shi)光(guang)伏建筑一(yi)體(ti)化發(fa)電(dian)(dian)系(xi)(xi)統(tong)，由(you)(you)于投資小、建設快、占地(di)面積小、政策支持力度大等優點(dian)，是(shi)并(bing)(bing)(bing)網(wang)(wang)光(guang)伏發(fa)電(dian)(dian)的主流。

分布式光伏發電

分布式光(guang)伏發電系統，又稱分散式發電或分布式供(gong)能，是指在用戶現(xian)場(chang)或靠近用電現(xian)場(chang)配置較小的(de)光(guang)伏發電供(gong)電系統，以滿(man)(man)足特定用戶的(de)需求(qiu)，支持(chi)現(xian)存(cun)配電網的(de)經濟運行，或者(zhe)同時滿(man)(man)足這兩(liang)個方(fang)面的(de)要求(qiu)。

　　分(fen)布式光伏發(fa)電(dian)(dian)系(xi)統(tong)的(de)基本設備包括光伏電(dian)(dian)池組件、光伏方陣支架、直流(liu)匯流(liu)箱、直流(liu)配(pei)(pei)電(dian)(dian)柜、并(bing)網逆(ni)變器、交(jiao)流(liu)配(pei)(pei)電(dian)(dian)柜等設備，另外(wai)還有供電(dian)(dian)系(xi)統(tong)監控裝置(zhi)和環境監測裝置(zhi)。其運行模式是在有太陽輻射的(de)條件下，光伏發(fa)電(dian)(dian)系(xi)統(tong)的(de)太陽能(neng)(neng)電(dian)(dian)池組件陣列將太陽能(neng)(neng)轉換輸出的(de)電(dian)(dian)能(neng)(neng)，經過直流(liu)匯流(liu)箱集(ji)中送入直流(liu)配(pei)(pei)電(dian)(dian)柜，由(you)并(bing)網逆(ni)變器逆(ni)變成交(jiao)流(liu)電(dian)(dian)供給建筑自(zi)身負載，多余或不足的(de)電(dian)(dian)力通過聯接(jie)電(dian)(dian)網來調節。
