輸送方式

太(tai)陽能光(guang)伏發電分為獨立光(guang)伏發電、并(bing)網光(guang)伏發電、分布式(shi)光(guang)伏發電

獨立光伏發電

獨立光伏發(fa)電(dian)(dian)系統也叫離網(wang)光伏發(fa)電(dian)(dian)系統。主要由(you)太陽能電(dian)(dian)池(chi)組件、控制器、蓄電(dian)(dian)池(chi)組成，若(ruo)要為交流負(fu)載供電(dian)(dian)，還需(xu)要配置(zhi)交流逆變器。

并網光伏發電

并(bing)網光(guang)伏(fu)(fu)發電(dian)(dian)系(xi)(xi)統(tong)就是太陽能(neng)(neng)組件(jian)產生的直流電(dian)(dian)經過并(bing)網逆變器轉換成符合市電(dian)(dian)電(dian)(dian)網要(yao)求(qiu)的交(jiao)流電(dian)(dian)之后直接(jie)接(jie)入公共電(dian)(dian)網。并(bing)網光(guang)伏(fu)(fu)發電(dian)(dian)系(xi)(xi)統(tong)有集(ji)中式大(da)型并(bing)網光(guang)伏(fu)(fu)電(dian)(dian)站(zhan)一般(ban)都(dou)是國家級(ji)電(dian)(dian)站(zhan)，主要(yao)特(te)點是將所(suo)發電(dian)(dian)能(neng)(neng)直接(jie)輸送(song)到電(dian)(dian)網，由(you)(you)電(dian)(dian)網統(tong)一調配向用戶(hu)供電(dian)(dian)。但這種電(dian)(dian)站(zhan)投(tou)資(zi)(zi)大(da)、建設周期(qi)長、占地(di)面(mian)積(ji)大(da)，發展(zhan)難度相對較大(da)。而分散式小(xiao)型并(bing)網光(guang)伏(fu)(fu)系(xi)(xi)統(tong)，特(te)別(bie)是光(guang)伏(fu)(fu)建筑一體化發電(dian)(dian)系(xi)(xi)統(tong)，由(you)(you)于投(tou)資(zi)(zi)小(xiao)、建設快、占地(di)面(mian)積(ji)小(xiao)、政(zheng)策支持力(li)度大(da)等優點，是并(bing)網光(guang)伏(fu)(fu)發電(dian)(dian)的主流。

分布式光伏發電

分(fen)布式光(guang)伏(fu)發電(dian)系統，又稱(cheng)分(fen)散(san)式發電(dian)或(huo)(huo)分(fen)布式供能，是指在(zai)用(yong)(yong)戶現(xian)(xian)場(chang)或(huo)(huo)靠近用(yong)(yong)電(dian)現(xian)(xian)場(chang)配(pei)置(zhi)較小的(de)光(guang)伏(fu)發電(dian)供電(dian)系統，以滿足特定用(yong)(yong)戶的(de)需求，支持(chi)現(xian)(xian)存配(pei)電(dian)網的(de)經(jing)濟(ji)運行，或(huo)(huo)者同時滿足這兩(liang)個方面(mian)的(de)要(yao)求。

　　分布式(shi)光(guang)(guang)伏(fu)發電(dian)(dian)(dian)系統的基本(ben)設(she)備包括光(guang)(guang)伏(fu)電(dian)(dian)(dian)池組件、光(guang)(guang)伏(fu)方陣(zhen)支架、直(zhi)(zhi)(zhi)(zhi)流(liu)匯(hui)流(liu)箱、直(zhi)(zhi)(zhi)(zhi)流(liu)配電(dian)(dian)(dian)柜(ju)、并網(wang)逆(ni)(ni)變器(qi)、交流(liu)配電(dian)(dian)(dian)柜(ju)等設(she)備，另外還(huan)有供(gong)電(dian)(dian)(dian)系統監(jian)控裝置和(he)環境監(jian)測(ce)裝置。其(qi)運行模式(shi)是在(zai)有太陽(yang)(yang)輻射的條件下，光(guang)(guang)伏(fu)發電(dian)(dian)(dian)系統的太陽(yang)(yang)能電(dian)(dian)(dian)池組件陣(zhen)列將太陽(yang)(yang)能轉換輸出的電(dian)(dian)(dian)能，經過直(zhi)(zhi)(zhi)(zhi)流(liu)匯(hui)流(liu)箱集中送入(ru)直(zhi)(zhi)(zhi)(zhi)流(liu)配電(dian)(dian)(dian)柜(ju)，由并網(wang)逆(ni)(ni)變器(qi)逆(ni)(ni)變成交流(liu)電(dian)(dian)(dian)供(gong)給建筑自(zi)身(shen)負載，多余或不足的電(dian)(dian)(dian)力通過聯接(jie)電(dian)(dian)(dian)網(wang)來調節。
