光伏發電系統(tong)對并網逆變器的(de)要求

要求(qiu)(qiu)具有較(jiao)高的可靠(kao)性：目前光伏發電(dian)系統主要用于邊遠地區(qu)，許多(duo)電(dian)站無人(ren)值守和維護，這(zhe)就要求(qiu)(qiu)逆交(jiao)(jiao)器(qi)具有合理的電(dian)路結(jie)構，嚴(yan)格(ge)的元(yuan)器(qi)件篩選，并要求(qiu)(qiu)逆變器(qi)具備(bei)各(ge)種保(bao)護功能，如輸入直(zhi)流(liu)極性接反保(bao)護，交(jiao)(jiao)流(liu)輸出短(duan)路保(bao)護，過熱，過載保(bao)護等。

要(yao)求逆變電源輸出正(zheng)弦(xian)波(bo)電流(liu)：大容量的(de)光伏發電系統(tong)并網運(yun)行(xing)時(shi)，為避免(mian)對公共電網的(de)電力污(wu)染，要(yao)求逆變電源輸出正(zheng)弦(xian)波(bo)電流(liu)。且能(neng)實(shi)現高的(de)功率(lv)因數的(de)正(zheng)弦(xian)波(bo)形。

很多人(ren)都知道光(guang)伏發電是(shi)太陽光(guang)通過(guo)太陽能(neng)(neng)光(guang)伏板(ban)(ban)將光(guang)能(neng)(neng)轉化為(wei)電能(neng)(neng)，那么太陽能(neng)(neng)光(guang)伏板(ban)(ban)是(shi)利(li)用什么原理來產生電能(neng)(neng)的(de)呢(ni)？太陽能(neng)(neng)光(guang)伏板(ban)(ban)的(de)構造是(shi)怎么樣的(de)呢(ni)？

目前太陽(yang)能(neng)光(guang)伏(fu)板(ban)主要有三種：單晶硅光(guang)伏(fu)板(ban)、多晶硅光(guang)伏(fu)板(ban)和非晶硅光(guang)伏(fu)板(ban)。

太陽(yang)能光伏板內的(de)太陽(yang)能電池通(tong)過(guo)串(chuan)聯(lian)的(de)形式再經(jing)過(guo)封(feng)裝(zhuang)保護，通(tong)過(guo)半導體材料(liao)的(de)光生(sheng)伏特(te)1效(xiao)應產生(sheng)電能。

光(guang)(guang)(guang)(guang)生伏(fu)(fu)(fu)(fu)(fu)特1效應(ying)的(de)(de)整個(ge)過(guo)程(cheng)都(dou)是(shi)(shi)借助半(ban)導體的(de)(de)光(guang)(guang)(guang)(guang)電(dian)(dian)(dian)反應(ying)，所(suo)(suo)以(yi)太陽(yang)能(neng)光(guang)(guang)(guang)(guang)發(fa)電(dian)(dian)(dian)又(you)被(bei)稱為光(guang)(guang)(guang)(guang)伏(fu)(fu)(fu)(fu)(fu)發(fa)電(dian)(dian)(dian)。太陽(yang)能(neng)光(guang)(guang)(guang)(guang)伏(fu)(fu)(fu)(fu)(fu)板(ban)是(shi)(shi)以(yi)半(ban)導體材(cai)料硅為原材(cai)料，光(guang)(guang)(guang)(guang)伏(fu)(fu)(fu)(fu)(fu)板(ban)的(de)(de)生產過(guo)程(cheng)中再(zai)加入硼。當太陽(yang)光(guang)(guang)(guang)(guang)照射在光(guang)(guang)(guang)(guang)伏(fu)(fu)(fu)(fu)(fu)板(ban)表(biao)面(mian)，光(guang)(guang)(guang)(guang)伏(fu)(fu)(fu)(fu)(fu)板(ban)內部(bu)載流(liu)子的(de)(de)運(yun)行速(su)度就會(hui)加快，光(guang)(guang)(guang)(guang)伏(fu)(fu)(fu)(fu)(fu)板(ban)內部(bu)的(de)(de)正(zheng)負電(dian)(dian)(dian)荷便會(hui)定向移動，于(yu)是(shi)(shi)就產生了電(dian)(dian)(dian)流(liu)。這就是(shi)(shi)光(guang)(guang)(guang)(guang)伏(fu)(fu)(fu)(fu)(fu)發(fa)電(dian)(dian)(dian)的(de)(de)整個(ge)運(yun)行原理(li)，所(suo)(suo)以(yi)光(guang)(guang)(guang)(guang)伏(fu)(fu)(fu)(fu)(fu)發(fa)電(dian)(dian)(dian)的(de)(de)過(guo)程(cheng)是(shi)(shi)完全(quan)綠色環保無任何污染的(de)(de)過(guo)程(cheng)。

光(guang)伏組件(jian)的維護

光(guang)(guang)(guang)伏組(zu)件(jian)(jian)(jian)應定(ding)期檢查(cha)，發(fa)現下列問題應立(li)即調整或更換光(guang)(guang)(guang)伏組(zu)件(jian)(jian)(jian)。光(guang)(guang)(guang)伏組(zu)件(jian)(jian)(jian)存(cun)在(zai)玻璃粉(fen)碎、背板灼焦(jiao)、明顯的顏色變化；光(guang)(guang)(guang)伏組(zu)件(jian)(jian)(jian)中存(cun)在(zai)與組(zu)件(jian)(jian)(jian)邊(bian)緣或任何電路(lu)之(zhi)間形成連通通道的氣泡；光(guang)(guang)(guang)伏組(zu)件(jian)(jian)(jian)接(jie)線(xian)(xian)盒(he)變形、扭曲、開裂或燒(shao)毀，接(jie)線(xian)(xian)端無法良好(hao)(hao)接(jie)觸(chu)(chu)；光(guang)(guang)(guang)伏組(zu)件(jian)(jian)(jian)上(shang)的帶(dai)電警告標(biao)識不得丟失；使用金屬邊(bian)框的光(guang)(guang)(guang)伏組(zu)件(jian)(jian)(jian)，邊(bian)框和支(zhi)架應結合良好(hao)(hao)，兩者之(zhi)間接(jie)觸(chu)(chu)電阻不大于4Ω，邊(bian)框必(bi)須牢固接(jie)地。
