在(zai)電(dian)(dian)氣自動化中使用和(he)推廣無功(gong)補(bu)償(chang)技術(shu)，不但能有效提升(sheng)企(qi)業(ye)電(dian)(dian)力(li)供應系統(tong)(tong)的效益，而且對(dui)(dui)(dui)降(jiang)低企(qi)業(ye)電(dian)(dian)力(li)運行(xing)成本(ben)，提升(sheng)企(qi)業(ye)經濟效益方面也(ye)有極為重要(yao)的意(yi)義。無功(gong)補(bu)償(chang)提高電(dian)(dian)力(li)系統(tong)(tong)的供應效率(lv)的途徑(jing)包括對(dui)(dui)(dui)并聯電(dian)(dian)容器進行(xing)無功(gong)補(bu)償(chang)和(he)對(dui)(dui)(dui)電(dian)(dian)網的無功(gong)率(lv)損(sun)耗進行(xing)補(bu)償(chang)兩種。

電(dian)力中無功補(bu)償元件經濟效(xiao)益(yi)分析

功(gong)率因(yin)數(shu)標準0.90，適用(yong)于160千伏(fu)(fu)(fu)安(an)(an)(an)以上(shang)的高壓(ya)(ya)供電(dian)(dian)(dian)工業(ye)用(yong)戶(hu)（包括社隊工業(ye)用(yong)戶(hu)）、裝有帶負荷(he)調整電(dian)(dian)(dian)壓(ya)(ya)裝置的高壓(ya)(ya)供電(dian)(dian)(dian)電(dian)(dian)(dian)力用(yong)戶(hu)和3200千伏(fu)(fu)(fu)安(an)(an)(an)及(ji)以上(shang)的高壓(ya)(ya)供電(dian)(dian)(dian)電(dian)(dian)(dian)力排灌站(zhan)。功(gong)率因(yin)數(shu)標準0.85，適用(yong)于100千伏(fu)(fu)(fu)安(an)(an)(an)（千瓦(wa)(wa)）及(ji)以上(shang)的其他工業(ye)用(yong)戶(hu)（包括社隊工業(ye)用(yong)戶(hu)）、100千伏(fu)(fu)(fu)安(an)(an)(an)（千瓦(wa)(wa)）及(ji)以上(shang)的非(fei)工業(ye)用(yong)戶(hu)和100千伏(fu)(fu)(fu)安(an)(an)(an)（千瓦(wa)(wa)）及(ji)以上(shang)的電(dian)(dian)(dian)力排灌站(zhan)。

跟蹤補(bu)償(chang)(chang)(chang)：是(shi)指(zhi)以(yi)無(wu)功補(bu)償(chang)(chang)(chang)投(tou)切裝(zhuang)置作(zuo)為控制(zhi)保護裝(zhuang)置，將低(di)壓(ya)電(dian)容(rong)器(qi)(qi)組補(bu)償(chang)(chang)(chang)在用(yong)(yong)戶(hu)配電(dian)變(bian)(bian)壓(ya)器(qi)(qi)低(di)壓(ya)側的(de)(de)補(bu)償(chang)(chang)(chang)方式。這種補(bu)償(chang)(chang)(chang)方式，部分相當于隨器(qi)(qi)補(bu)償(chang)(chang)(chang)的(de)(de)作(zuo)用(yong)(yong)，主要適用(yong)(yong)與(yu)100kVA及以(yi)上的(de)(de)專用(yong)(yong)配電(dian)變(bian)(bian)壓(ya)器(qi)(qi)用(yong)(yong)戶(hu)。跟蹤補(bu)償(chang)(chang)(chang)的(de)(de)優點是(shi)可(ke)較(jiao)(jiao)好(hao)地(di)跟蹤無(wu)功負荷的(de)(de)變(bian)(bian)化，運行方式靈活，補(bu)償(chang)(chang)(chang)效果好(hao)，但是(shi)費用(yong)(yong)高(gao)，且自動投(tou)切裝(zhuang)置較(jiao)(jiao)隨機(ji)或隨器(qi)(qi)補(bu)償(chang)(chang)(chang)的(de)(de)控制(zhi)保護裝(zhuang)置復(fu)雜，如有(you)任一元件損壞，則可(ke)導致電(dian)容(rong)器(qi)(qi)不能投(tou)切。其主要適于大容(rong)量大負荷的(de)(de)配變(bian)(bian)。
