為了保證電(dian)(dian)力電(dian)(dian)網運行的(de)(de)(de)(de)(de)穩(wen)定性(xing)(xing)和安(an)全性(xing)(xing)，都(dou)會(hui)安(an)裝了一(yi)些相關(guan)的(de)(de)(de)(de)(de)無(wu)功補(bu)(bu)償設備，其(qi)實(shi)無(wu)功補(bu)(bu)償在(zai)節(jie)電(dian)(dian)方面(mian)的(de)(de)(de)(de)(de)效(xiao)(xiao)果也(ye)是非常明顯的(de)(de)(de)(de)(de)，所以(yi)深受(shou)企業的(de)(de)(de)(de)(de)歡迎。下面(mian)就(jiu)重(zhong)點(dian)來分(fen)析一(yi)下無(wu)功補(bu)(bu)償措(cuo)施(shi)的(de)(de)(de)(de)(de)優(you)異性(xing)(xing)能。電(dian)(dian)網系統中被用(yong)(yong)到的(de)(de)(de)(de)(de)無(wu)功補(bu)(bu)償的(de)(de)(de)(de)(de)方式(shi)有很多(duo)，包括集(ji)中補(bu)(bu)償、單臺(tai)電(dian)(dian)動機就(jiu)地補(bu)(bu)償和分(fen)組補(bu)(bu)償，每種補(bu)(bu)償方式(shi)都(dou)有各自(zi)的(de)(de)(de)(de)(de)特點(dian)，使用(yong)(yong)的(de)(de)(de)(de)(de)時候也(ye)略有不同。但(dan)是這些并不會(hui)影響其(qi)優(you)異的(de)(de)(de)(de)(de)使用(yong)(yong)效(xiao)(xiao)果，特別是在(zai)節(jie)電(dian)(dian)方面(mian)的(de)(de)(de)(de)(de)。

冶金行業無(wu)功補償解決方案

起重機或電(dian)(dian)(dian)(dian)梯等在重物下降時，電(dian)(dian)(dian)(dian)動機運行(xing)于(yu)第四象(xiang)限，為避免過電(dian)(dian)(dian)(dian)壓(ya)(ya)，不(bu)宜(yi)單(dan)獨用(yong)電(dian)(dian)(dian)(dian)容(rong)器(qi)(qi)(qi)補(bu)償。對于(yu)多速電(dian)(dian)(dian)(dian)動機，如不(bu)停電(dian)(dian)(dian)(dian)進(jin)(jin)行(xing)變壓(ya)(ya)及變速，也(ye)(ye)容(rong)易產(chan)生(sheng)過電(dian)(dian)(dian)(dian)壓(ya)(ya)，也(ye)(ye)不(bu)宜(yi)單(dan)獨用(yong)電(dian)(dian)(dian)(dian)容(rong)器(qi)(qi)(qi)補(bu)償。如對這些(xie)用(yong)電(dian)(dian)(dian)(dian)設備(bei)(bei)需要采用(yong)電(dian)(dian)(dian)(dian)容(rong)器(qi)(qi)(qi)單(dan)獨補(bu)償，應(ying)為電(dian)(dian)(dian)(dian)容(rong)器(qi)(qi)(qi)單(dan)獨設置控制設備(bei)(bei)，操作時先停電(dian)(dian)(dian)(dian)再進(jin)(jin)行(xing)切換，避免產(chan)生(sheng)過電(dian)(dian)(dian)(dian)壓(ya)(ya)。

負荷功率(lv)(lv)(lv)因數低、線路壓降大(da)，需(xu)要(yao)(yao)進行無功功率(lv)(lv)(lv)補(bu)償的(de)場合、負載功率(lv)(lv)(lv)變(bian)(bian)化大(da)，變(bian)(bian)化速度快的(de)場合、有諧波源（如(ru)直流(liu)調(diao)速、變(bian)(bian)頻(pin)調(diao)速、變(bian)(bian)頻(pin)爐等(deng)）諧波污染嚴重需(xu)要(yao)(yao)抑制或治理諧波的(de)場合，負載三相不平衡的(de)場合，對(dui)電壓波動和(he)動態補(bu)償有較高要(yao)(yao)求(qiu)的(de)場合。
