山東(dong)省青州市魯東(dong)機(ji)械2.1MW光伏(fu)發電(dian)站(zhan)(zhan)項(xiang)目。彩鋼瓦屋(wu)頂(ding)光伏(fu)發電(dian)站(zhan)(zhan)，已(yi)并網發電(dian)成功！

輸送方式

太(tai)陽(yang)能光伏(fu)發(fa)電(dian)分為(wei)獨立光伏(fu)發(fa)電(dian)、并網光伏(fu)發(fa)電(dian)、分布式光伏(fu)發(fa)電(dian)

獨立光伏發電

獨立(li)光(guang)伏發電系統(tong)也叫(jiao)離網(wang)光(guang)伏發電系統(tong)。主要(yao)由太(tai)陽(yang)能電池(chi)組(zu)件、控制器(qi)、蓄電池(chi)組(zu)成(cheng)，若要(yao)為交流負載(zai)供電，還需要(yao)配置交流逆變器(qi)。

并網光伏發電

并(bing)(bing)網光伏(fu)(fu)發(fa)電(dian)(dian)(dian)系(xi)統(tong)就是(shi)太陽能組件產生的直(zhi)流電(dian)(dian)(dian)經(jing)過(guo)并(bing)(bing)網逆(ni)變器轉換成(cheng)符合市電(dian)(dian)(dian)電(dian)(dian)(dian)網要求(qiu)的交流電(dian)(dian)(dian)之后(hou)直(zhi)接接入公(gong)共電(dian)(dian)(dian)網。并(bing)(bing)網光伏(fu)(fu)發(fa)電(dian)(dian)(dian)系(xi)統(tong)有(you)集中式(shi)大(da)型并(bing)(bing)網光伏(fu)(fu)電(dian)(dian)(dian)站(zhan)一(yi)(yi)般都是(shi)國家級電(dian)(dian)(dian)站(zhan)，主要特點是(shi)將所發(fa)電(dian)(dian)(dian)能直(zhi)接輸送到電(dian)(dian)(dian)網，由電(dian)(dian)(dian)網統(tong)一(yi)(yi)調配向用戶供電(dian)(dian)(dian)。但這種(zhong)電(dian)(dian)(dian)站(zhan)投資大(da)、建(jian)設周期長(chang)、占地(di)面積大(da)，發(fa)展難度相對較大(da)。而分(fen)散(san)式(shi)小型并(bing)(bing)網光伏(fu)(fu)系(xi)統(tong)，特別是(shi)光伏(fu)(fu)建(jian)筑一(yi)(yi)體化發(fa)電(dian)(dian)(dian)系(xi)統(tong)，由于投資小、建(jian)設快、占地(di)面積小、政(zheng)策支(zhi)持力(li)度大(da)等優點，是(shi)并(bing)(bing)網光伏(fu)(fu)發(fa)電(dian)(dian)(dian)的主流。

分布式光伏發電

分(fen)布式(shi)光(guang)伏發電(dian)(dian)系統，又稱分(fen)散式(shi)發電(dian)(dian)或分(fen)布式(shi)供(gong)(gong)能，是(shi)指在用(yong)戶現場或靠近用(yong)電(dian)(dian)現場配置(zhi)較小(xiao)的(de)(de)光(guang)伏發電(dian)(dian)供(gong)(gong)電(dian)(dian)系統，以滿(man)(man)足特(te)定用(yong)戶的(de)(de)需(xu)求(qiu)，支持現存配電(dian)(dian)網的(de)(de)經(jing)濟運(yun)行，或者同時滿(man)(man)足這兩個方面的(de)(de)要求(qiu)。

　　分布式(shi)光伏發電(dian)(dian)(dian)系統(tong)的(de)基(ji)本設(she)備包括光伏電(dian)(dian)(dian)池組件、光伏方陣(zhen)(zhen)支架、直(zhi)(zhi)流(liu)(liu)匯(hui)(hui)流(liu)(liu)箱、直(zhi)(zhi)流(liu)(liu)配電(dian)(dian)(dian)柜、并網逆(ni)變(bian)器、交(jiao)流(liu)(liu)配電(dian)(dian)(dian)柜等設(she)備，另外還(huan)有供電(dian)(dian)(dian)系統(tong)監控裝置(zhi)和環境監測裝置(zhi)。其運行模式(shi)是在(zai)有太(tai)(tai)陽輻射的(de)條(tiao)件下，光伏發電(dian)(dian)(dian)系統(tong)的(de)太(tai)(tai)陽能電(dian)(dian)(dian)池組件陣(zhen)(zhen)列將太(tai)(tai)陽能轉換輸出的(de)電(dian)(dian)(dian)能，經過直(zhi)(zhi)流(liu)(liu)匯(hui)(hui)流(liu)(liu)箱集中(zhong)送入直(zhi)(zhi)流(liu)(liu)配電(dian)(dian)(dian)柜，由(you)并網逆(ni)變(bian)器逆(ni)變(bian)成交(jiao)流(liu)(liu)電(dian)(dian)(dian)供給建筑自(zi)身負載，多余或不足的(de)電(dian)(dian)(dian)力通(tong)過聯接電(dian)(dian)(dian)網來調(diao)節。
