高壓(ya)集中(zhong)補(bu)(bu)償(chang)(chang)是指(zhi)并聯電容器組直(zhi)接安裝在變電站6~10kV高壓(ya)母線上的(de)補(bu)(bu)償(chang)(chang)方式。適(shi)用于在用戶遠(yuan)離供電線路(lu)末端變電站且有一定高壓(ya)負荷(he)的(de)情(qing)況下，降低電力系(xi)統的(de)無功功耗(hao)，起到(dao)一定的(de)補(bu)(bu)償(chang)(chang)作用；補(bu)(bu)償(chang)(chang)裝置根據負載自動(dong)切換，補(bu)(bu)償(chang)(chang)效益(yi)高。

純電容(rong)低壓(ya)補償(chang)模組優缺點(dian)分析

在一定的(de)有功(gong)(gong)(gong)功(gong)(gong)(gong)率下(xia)，功(gong)(gong)(gong)率因數越小，所(suo)需的(de)無(wu)(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率越大。為滿足用(yong)電(dian)(dian)的(de)需求，供(gong)電(dian)(dian)線(xian)路(lu)和(he)變(bian)壓器的(de)容量(liang)就(jiu)需要(yao)增(zeng)加，這樣不僅要(yao)增(zeng)加供(gong)電(dian)(dian)投資、降低設備(bei)利(li)用(yong)率，也(ye)將增(zeng)加線(xian)路(lu)損耗。為了提(ti)高電(dian)(dian)網(wang)的(de)經濟(ji)運行效(xiao)率，根據(ju)電(dian)(dian)網(wang)中的(de)無(wu)(wu)功(gong)(gong)(gong)類型，人為的(de)補(bu)(bu)償(chang)容性無(wu)(wu)功(gong)(gong)(gong)或感性無(wu)(wu)功(gong)(gong)(gong)來抵(di)消線(xian)路(lu)的(de)無(wu)(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率，這就(jiu)是無(wu)(wu)功(gong)(gong)(gong)補(bu)(bu)償(chang)柜的(de)主要(yao)用(yong)途。
