電(dian)(dian)網(wang)輸出的(de)功(gong)(gong)率(lv)包括兩部分(fen);一(yi)是(shi)(shi)有(you)功(gong)(gong)功(gong)(gong)率(lv);二是(shi)(shi)無(wu)(wu)功(gong)(gong)功(gong)(gong)率(lv).直接消(xiao)耗(hao)電(dian)(dian)能(neng)(neng)(neng)(neng)(neng),把(ba)電(dian)(dian)能(neng)(neng)(neng)(neng)(neng)轉變(bian)為(wei)機械(xie)能(neng)(neng)(neng)(neng)(neng),熱能(neng)(neng)(neng)(neng)(neng),化學能(neng)(neng)(neng)(neng)(neng)或聲能(neng)(neng)(neng)(neng)(neng),利用這些(xie)能(neng)(neng)(neng)(neng)(neng)作(zuo)功(gong)(gong),這部分(fen)功(gong)(gong)率(lv)稱為(wei)有(you)功(gong)(gong)功(gong)(gong)率(lv);不消(xiao)耗(hao)電(dian)(dian)能(neng)(neng)(neng)(neng)(neng);只是(shi)(shi)把(ba)電(dian)(dian)能(neng)(neng)(neng)(neng)(neng)轉換為(wei)另一(yi)種形式的(de)能(neng)(neng)(neng)(neng)(neng),這種能(neng)(neng)(neng)(neng)(neng)作(zuo)為(wei)電(dian)(dian)氣設備能(neng)(neng)(neng)(neng)(neng)夠作(zuo)功(gong)(gong)的(de)必備條件(jian),并且,這種能(neng)(neng)(neng)(neng)(neng)是(shi)(shi)在電(dian)(dian)網(wang)中與電(dian)(dian)能(neng)(neng)(neng)(neng)(neng)進(jin)行(xing)周(zhou)期性轉換,這部分(fen)功(gong)(gong)率(lv)稱為(wei)無(wu)(wu)功(gong)(gong)功(gong)(gong)率(lv),如電(dian)(dian)磁(ci)(ci)元(yuan)件(jian)建立磁(ci)(ci)場占(zhan)(zhan)用的(de)電(dian)(dian)能(neng)(neng)(neng)(neng)(neng),電(dian)(dian)容器建立電(dian)(dian)場所占(zhan)(zhan)的(de)電(dian)(dian)能(neng)(neng)(neng)(neng)(neng).

純電(dian)容低壓(ya)補償(chang)模組的(de)補償(chang)標(biao)準是(shi)什(shen)么(me)

在(zai)一定的(de)有功(gong)(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)(gong)率(lv)下，功(gong)(gong)(gong)(gong)(gong)率(lv)因數越(yue)(yue)小，所需(xu)的(de)無(wu)(wu)(wu)功(gong)(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)(gong)率(lv)越(yue)(yue)大。為(wei)滿足用(yong)(yong)電(dian)(dian)的(de)需(xu)求，供電(dian)(dian)線路(lu)和變壓器的(de)容量就需(xu)要增加(jia)(jia)，這樣不(bu)僅要增加(jia)(jia)供電(dian)(dian)投資(zi)、降低(di)設備利(li)用(yong)(yong)率(lv)，也將(jiang)增加(jia)(jia)線路(lu)損耗(hao)。為(wei)了提高電(dian)(dian)網(wang)的(de)經濟運行效率(lv)，根(gen)據電(dian)(dian)網(wang)中的(de)無(wu)(wu)(wu)功(gong)(gong)(gong)(gong)(gong)類型，人為(wei)的(de)補(bu)償(chang)容性(xing)無(wu)(wu)(wu)功(gong)(gong)(gong)(gong)(gong)或感性(xing)無(wu)(wu)(wu)功(gong)(gong)(gong)(gong)(gong)來(lai)抵消線路(lu)的(de)無(wu)(wu)(wu)功(gong)(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)(gong)率(lv)，這就是無(wu)(wu)(wu)功(gong)(gong)(gong)(gong)(gong)補(bu)償(chang)柜的(de)主要用(yong)(yong)途。

另一(yi)種是被動型諧波(bo)抑制方案，即諧波(bo)負載本(ben)身(shen)不(bu)加(jia)(jia)改變，而是在電(dian)力系統或諧波(bo)負載的交流側加(jia)(jia)裝無源濾(lv)波(bo)器(qi)(qi)、有(you)源電(dian)力濾(lv)波(bo)器(qi)(qi)等(deng)裝置，通過外加(jia)(jia)設備對電(dian)網實施諧波(bo)補(bu)償，但是無源濾(lv)波(bo)器(qi)(qi)濾(lv)除(chu)效果(guo)差，并(bing)且只能針(zhen)對單獨某一(yi)次進行濾(lv)除(chu)，所(suo)以行業內(nei)大多選用有(you)源電(dian)力濾(lv)波(bo)器(qi)(qi)進行諧波(bo)補(bu)償。
