變(bian)頻器表現出的(de)(de)各種諧(xie)波問題嗎，是可以想辦(ban)法治理(li)的(de)(de)，關鍵就(jiu)在于要抑制(zhi)(zhi)輻射(she)(she)干擾(rao)(rao)和供電(dian)系統的(de)(de)干擾(rao)(rao)。究竟哪些技術手段對變(bian)頻器諧(xie)波治理(li)會比較有效呢？不(bu)妨嘗試(shi)以下(xia)措施(shi)。比如(ru)說可以在變(bian)頻器輸(shu)(shu)入(ru)側與(yu)輸(shu)(shu)出側串接合適的(de)(de)電(dian)抗器，用以吸收(shou)諧(xie)波和增(zeng)大(da)電(dian)源或負載的(de)(de)阻抗，達到抑制(zhi)(zhi)諧(xie)波的(de)(de)目(mu)的(de)(de)，以減少(shao)傳輸(shu)(shu)過程中的(de)(de)電(dian)磁輻射(she)(she)。通(tong)過抑制(zhi)(zhi)諧(xie)波電(dian)流，使得變(bian)頻器的(de)(de)功率因數有所提(ti)高(gao)。

首次(ci)裝(zhuang)置補償模(mo)組(zu)的補償標(biao)準是什么(me)

而對重要變電(dian)(dian)(dian)(dian)站或實施無(wu)人(ren)值班變電(dian)(dian)(dian)(dian)站的公共配(pei)電(dian)(dian)(dian)(dian)點(dian)或重要電(dian)(dian)(dian)(dian)力(li)用(yong)戶的配(pei)電(dian)(dian)(dian)(dian)點(dian)可實行電(dian)(dian)(dian)(dian)能質(zhi)量在線連續監測。在線檢測主要適用(yong)于監測電(dian)(dian)(dian)(dian)網電(dian)(dian)(dian)(dian)壓(ya)質(zhi)量偏(pian)差(cha)、三相(xiang)電(dian)(dian)(dian)(dian)壓(ya)不平衡(heng)、電(dian)(dian)(dian)(dian)壓(ya)諧(xie)波等狀(zhuang)態，以及電(dian)(dian)(dian)(dian)力(li)用(yong)戶負荷(he)注入公用(yong)電(dian)(dian)(dian)(dian)網的諧(xie)波電(dian)(dian)(dian)(dian)流和負序電(dian)(dian)(dian)(dian)流等指(zhi)標。

這是一個功率(lv)因(yin)數很低且(qie)三(san)(san)相(xiang)嚴重不平(ping)衡(heng)的(de)例子，三(san)(san)相(xiang)的(de)功率(lv)因(yin)數均為(wei)0.707。C相(xiang)電(dian)流(liu)(liu)比(bi)A相(xiang)電(dian)流(liu)(liu)大(da)一倍。在這個例子里，由于(yu)負荷含有足夠多的(de)電(dian)感，因(yin)此只要(yao)恰當地投入電(dian)容(rong)器，就可以使三(san)(san)相(xiang)的(de)功率(lv)因(yin)數均為(wei)1，并(bing)且(qie)三(san)(san)相(xiang)電(dian)流(liu)(liu)平(ping)衡(heng)。
