電網(wang)(wang)無(wu)(wu)功(gong)補(bu)償(chang)是(shi)一(yi)項建設性的技術措施，對電網(wang)(wang)安全、優質、經濟(ji)運行(xing)有重要作用。電網(wang)(wang)和負載的特點選擇(ze)合(he)理(li)的補(bu)償(chang)方式是(shi)有效(xiao)(xiao)補(bu)償(chang)的關鍵。針對目前電網(wang)(wang)諧波污染嚴重的現狀(zhuang)，在做無(wu)(wu)功(gong)補(bu)償(chang)時一(yi)定(ding)要選擇(ze)合(he)適的裝置，避免(mian)諧振和諧波放大的現象,保(bao)證電容(rong)電抗的壽命和無(wu)(wu)功(gong)補(bu)償(chang)裝置的補(bu)償(chang)效(xiao)(xiao)果(guo)，為客戶創造(zao)價(jia)值。

目前，純居民生活用(yong)(yong)電的(de)農村綜合(he)變(bian)已經(jing)不存在(zai)了(le)，絕大多數農村綜合(he)變(bian)的(de)非(fei)普工業(ye)用(yong)(yong)電占到(dao)60％以上（小(xiao)集鎮公用(yong)(yong)變(bian)和(he)排(pai)灌變(bian)除外）。由(you)(you)于低壓(ya)動(dong)力客戶都沒(mei)有(you)進行(xing)無(wu)(wu)功(gong)就地(di)補(bu)償，網改(gai)時由(you)(you)于資金(jin)不足等原因(yin)也未(wei)考(kao)慮低壓(ya)無(wu)(wu)功(gong)補(bu)償問題(ti)，導致農村綜合(he)變(bian)的(de)功(gong)率(lv)因(yin)數很(hen)低，基本上在(zai)0.6～0.7之間(jian)，即無(wu)(wu)功(gong)功(gong)率(lv)在(zai)配(pei)電線路上引(yin)起(qi)的(de)有(you)功(gong)損耗實際(ji)上超過了(le)有(you)功(gong)功(gong)率(lv)在(zai)配(pei)電線路上引(yin)起(qi)的(de)有(you)功(gong)損耗。因(yin)此，從技術(shu)面分析，無(wu)(wu)功(gong)功(gong)率(lv)引(yin)起(qi)的(de)有(you)功(gong)損耗已經(jing)成為影響整個(ge)低壓(ya)配(pei)電系統線損率(lv) 主(zhu)要的(de)技術(shu)因(yin)素。
