電(dian)(dian)力系(xi)(xi)統(tong)(tong)(tong)具(ju)有(you)較強的地(di)(di)區性特點(dian)。簡單(dan)來說(shuo)，就(jiu)是(shi)必須因地(di)(di)制宜，不(bu)(bu)(bu)同(tong)(tong)國(guo)家之間的電(dian)(dian)力系(xi)(xi)統(tong)(tong)(tong)規范不(bu)(bu)(bu)同(tong)(tong)：比如額定電(dian)(dian)壓、額定頻率不(bu)(bu)(bu)一(yi)樣。國(guo)內不(bu)(bu)(bu)同(tong)(tong)地(di)(di)區呢(ni)，電(dian)(dian)力系(xi)(xi)統(tong)(tong)(tong)組成情況(kuang)，電(dian)(dian)源、負荷要求也(ye)不(bu)(bu)(bu)一(yi)樣，還有(you)電(dian)(dian)氣設備運行環境也(ye)不(bu)(bu)(bu)同(tong)(tong)。正因為有(you)了(le)差異性，使(shi)得電(dian)(dian)力系(xi)(xi)統(tong)(tong)(tong)的發(fa)展各具(ju)特色，電(dian)(dian)力系(xi)(xi)統(tong)(tong)(tong)的規劃(hua)、設計(ji)、運行等不(bu)(bu)(bu)能盲目搬(ban)用其它(ta)系(xi)(xi)統(tong)(tong)(tong)的經(jing)驗，得根據本地(di)(di)的實際情況(kuang)采(cai)用不(bu)(bu)(bu)同(tong)(tong)的對策了(le)。

冶金行(xing)業(ye)(ye)無功補(bu)償元件(jian)在光(guang)伏產業(ye)(ye)中的作用

這種情況下，就(jiu)需要在對(dui)(dui)無(wu)功(gong)有要求的(de)(de)(de)負載處就(jiu)近提(ti)供無(wu)功(gong)補(bu)(bu)(bu)償。得到無(wu)功(gong)功(gong)率補(bu)(bu)(bu)償之后(hou)，無(wu)功(gong)能(neng)(neng)量才能(neng)(neng)在負載和近處的(de)(de)(de)補(bu)(bu)(bu)償器之間流(liu)動(dong)，電(dian)網不需要提(ti)供這一部分的(de)(de)(de)能(neng)(neng)量，降低(di)了對(dui)(dui)電(dian)網的(de)(de)(de)容量的(de)(de)(de)要求，也(ye)避(bi)免了引起線路(lu)壓降的(de)(de)(de)問題。

從以上的(de)(de)(de)例子(zi)可(ke)以看(kan)出(chu)，只要恰當地在系統的(de)(de)(de)各相(xiang)線(xian)與(yu)相(xiang)線(xian)之間及(ji)各相(xiang)線(xian)與(yu)零線(xian)之間接入不同數量的(de)(de)(de)單相(xiang)電容(rong)器(qi)，就可(ke)以達到即補償(chang)功率因(yin)數又調整不平衡有(you)功電流的(de)(de)(de)目的(de)(de)(de)。并(bing)且投(tou)入的(de)(de)(de)電容(rong)器(qi)總量與(yu)將三相(xiang)的(de)(de)(de)功率因(yin)數均補償(chang)至1所(suo)需的(de)(de)(de)電容(rong)器(qi)總量相(xiang)同。雖然計算方法十分復(fu)雜(za)，但(dan)在計算機技術(shu)高度發達的(de)(de)(de)今天(tian)，實現起來還(huan)是沒有(you)問題的(de)(de)(de)。
