人工(gong)補(bu)(bu)償(chang)無(wu)功(gong)功(gong)率(lv)，經(jing)(jing)常(chang)采(cai)用兩種方法，一(yi)種是同(tong)(tong)步(bu)電(dian)動機(ji)(ji)超(chao)(chao)前(qian)運(yun)(yun)行(xing)，一(yi)種是采(cai)用電(dian)容器(qi)補(bu)(bu)償(chang)。同(tong)(tong)步(bu)電(dian)動機(ji)(ji)價格貴，操(cao)作(zuo)(zuo)控制復雜，本(ben)身損耗(hao)也較大(da)，不(bu)僅采(cai)用小容量(liang)同(tong)(tong)步(bu)電(dian)動機(ji)(ji)不(bu)經(jing)(jing)濟，即使容量(liang)較大(da)而且(qie)長期連續運(yun)(yun)行(xing)的同(tong)(tong)步(bu)電(dian)動機(ji)(ji)也正為異(yi)步(bu)電(dian)動機(ji)(ji)加(jia)電(dian)容器(qi)補(bu)(bu)償(chang)所代替，同(tong)(tong)時操(cao)作(zuo)(zuo)工(gong)人往往擔(dan)心同(tong)(tong)步(bu)電(dian)動機(ji)(ji)超(chao)(chao)前(qian)運(yun)(yun)行(xing)會增(zeng)加(jia)維修工(gong)作(zuo)(zuo)量(liang)，經(jing)(jing)常(chang)將設計中(zhong)的超(chao)(chao)前(qian)運(yun)(yun)行(xing)同(tong)(tong)步(bu)電(dian)動機(ji)(ji)作(zuo)(zuo)滯后運(yun)(yun)行(xing)，喪失了采(cai)用同(tong)(tong)步(bu)電(dian)動機(ji)(ji)的優點。因此，除上述工(gong)藝條件適當者外，不(bu)宜選用同(tong)(tong)步(bu)電(dian)動機(ji)(ji)。當然，通(tong)過技術經(jing)(jing)濟比(bi)較，當采(cai)用同(tong)(tong)步(bu)電(dian)動機(ji)(ji)作(zuo)(zuo)為無(wu)功(gong)補(bu)(bu)償(chang)裝置(zhi)確(que)實(shi)合理時，也可(ke)采(cai)用同(tong)(tong)步(bu)電(dian)動機(ji)(ji)作(zuo)(zuo)為無(wu)功(gong)補(bu)(bu)償(chang)裝置(zhi)。

冶金行業(ye)無功補償元(yuan)件(jian)設計時需要注意(yi)的(de)事項

另(ling)一(yi)(yi)方面，利用(yong)(yong)無(wu)功(gong)(gong)補償設(she)備進行(xing)無(wu)功(gong)(gong)補償，可(ke)以(yi)有效(xiao)(xiao)地減少對(dui)有功(gong)(gong)功(gong)(gong)率(lv)的(de)損耗(hao)，可(ke)以(yi)節約電(dian)(dian)器設(she)備資(zi)金，從另(ling)一(yi)(yi)個側面來看可(ke)以(yi)提升有功(gong)(gong)功(gong)(gong)率(lv)的(de)利用(yong)(yong)效(xiao)(xiao)率(lv)，從而減少了用(yong)(yong)電(dian)(dian)費用(yong)(yong)。通過對(dui)比發現，在同樣的(de)消耗(hao)中，使(shi)用(yong)(yong)無(wu)功(gong)(gong)補償技術的(de)企業(ye)要比未(wei)采(cai)用(yong)(yong)無(wu)功(gong)(gong)補償技術的(de)企業(ye)生產效(xiao)(xiao)率(lv)更高，電(dian)(dian)費等相關支出(chu)費用(yong)(yong)更少，電(dian)(dian)力運行(xing)效(xiao)(xiao)率(lv)更為穩定，企業(ye)生產成(cheng)本(ben)大(da)幅度降低。

根(gen)據現(xian)行國家標準《并聯電容(rong)(rong)器裝(zhuang)置設計(ji)規范(fan)》GB 50227—2008中第3.0.2條的(de)要求，變(bian)電站的(de)電容(rong)(rong)器安裝(zhuang)容(rong)(rong)量，應根(gen)據本(ben)地區電網無(wu)功規劃和國家現(xian)行標準中有關規定經計(ji)算(suan)后確定，也可根(gen)據有關規定按(an)變(bian)壓(ya)器容(rong)(rong)量進行估算(suan)。當不具備設計(ji)計(ji)算(suan)條件時，電容(rong)(rong)器安裝(zhuang)容(rong)(rong)量可按(an)變(bian)壓(ya)器容(rong)(rong)量的(de)10％～30％確定。
