山東省青州市魯東機械2.1MW光伏(fu)發電(dian)(dian)站(zhan)項目。彩鋼瓦屋頂(ding)光伏(fu)發電(dian)(dian)站(zhan)，已并網(wang)發電(dian)(dian)成功(gong)！

輸送方式

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

獨立光伏發電

獨(du)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(yao)(yao)(yao)由(you)太陽能電池組件、控制器、蓄電池組成，若要(yao)(yao)(yao)為交(jiao)流負載(zai)供(gong)電，還需要(yao)(yao)(yao)配置交(jiao)流逆變器。

并網光伏發電

并(bing)(bing)網光(guang)(guang)伏(fu)(fu)發(fa)電(dian)(dian)(dian)(dian)系(xi)統(tong)就是太陽能(neng)組件產生的(de)直(zhi)流(liu)電(dian)(dian)(dian)(dian)經過并(bing)(bing)網逆(ni)變器轉(zhuan)換(huan)成符合市電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)網要求的(de)交流(liu)電(dian)(dian)(dian)(dian)之后直(zhi)接接入公共(gong)電(dian)(dian)(dian)(dian)網。并(bing)(bing)網光(guang)(guang)伏(fu)(fu)發(fa)電(dian)(dian)(dian)(dian)系(xi)統(tong)有集中式(shi)大(da)(da)(da)型并(bing)(bing)網光(guang)(guang)伏(fu)(fu)電(dian)(dian)(dian)(dian)站一(yi)般都(dou)是國家級電(dian)(dian)(dian)(dian)站，主要特點是將(jiang)所發(fa)電(dian)(dian)(dian)(dian)能(neng)直(zhi)接輸送到電(dian)(dian)(dian)(dian)網，由(you)電(dian)(dian)(dian)(dian)網統(tong)一(yi)調配向(xiang)用戶供電(dian)(dian)(dian)(dian)。但這種(zhong)電(dian)(dian)(dian)(dian)站投資(zi)大(da)(da)(da)、建設(she)周期長、占(zhan)地面積大(da)(da)(da)，發(fa)展難度相(xiang)對較大(da)(da)(da)。而分(fen)散(san)式(shi)小(xiao)型并(bing)(bing)網光(guang)(guang)伏(fu)(fu)系(xi)統(tong)，特別是光(guang)(guang)伏(fu)(fu)建筑一(yi)體化發(fa)電(dian)(dian)(dian)(dian)系(xi)統(tong)，由(you)于(yu)投資(zi)小(xiao)、建設(she)快、占(zhan)地面積小(xiao)、政策支持力度大(da)(da)(da)等(deng)優點，是并(bing)(bing)網光(guang)(guang)伏(fu)(fu)發(fa)電(dian)(dian)(dian)(dian)的(de)主流(liu)。

分布式光伏發電

分布式光伏發電(dian)系(xi)(xi)統，又稱分散式發電(dian)或(huo)分布式供(gong)能，是指在(zai)用(yong)戶現場或(huo)靠近用(yong)電(dian)現場配置較小的(de)光伏發電(dian)供(gong)電(dian)系(xi)(xi)統，以滿足(zu)特(te)定(ding)用(yong)戶的(de)需求，支持(chi)現存配電(dian)網的(de)經濟(ji)運(yun)行，或(huo)者同時滿足(zu)這兩個方面的(de)要求。

　　分(fen)布式光(guang)伏發(fa)電系(xi)統的(de)基本(ben)設備(bei)包括光(guang)伏電池(chi)組件、光(guang)伏方陣支架、直流(liu)匯流(liu)箱(xiang)、直流(liu)配電柜(ju)、并(bing)網逆變器、交流(liu)配電柜(ju)等設備(bei)，另外還有供電系(xi)統監控裝置(zhi)(zhi)和環境監測裝置(zhi)(zhi)。其運行(xing)模(mo)式是在(zai)有太陽輻射的(de)條件下，光(guang)伏發(fa)電系(xi)統的(de)太陽能電池(chi)組件陣列將太陽能轉換輸(shu)出(chu)的(de)電能，經(jing)過直流(liu)匯流(liu)箱(xiang)集中(zhong)送(song)入直流(liu)配電柜(ju)，由并(bing)網逆變器逆變成交流(liu)電供給建筑自身負載，多(duo)余或不足的(de)電力(li)通(tong)過聯(lian)接電網來調節。
