由(you)於(yu)所(suo)處(chu)立(li)場(chang)不(bu)同(tong)，關(guan)注(zhu)或(huo)表(biao)征(zheng)電(dian)能(neng)質(zhi)量(liang)的(di)角(jue)度(duo)不(bu)同(tong)，人(ren)們(men)對(dui)電(dian)能(neng)質(zhi)量(liang)的(di)定(ding)義(yi)還(huan)未(wei)能(neng)達(da)成(cheng)完(wan)全(quan)的(di)共(gong)識(zhi)，但(dan)是(shi)對(dui)其(qi)主(zhu)要(yao)技(ji)術(zhu)指(zhi)標(biao)都(du)有(you)較(jiao)為(wei)一(yi)致(zhi)的(di)認(ren)識(zhi)。
(1) 電(dian)壓(ya)偏(pian)差(chai)(voltage deviation)：是(shi)電(dian)壓(ya)下(xia)跌(die)(電(dian)壓(ya)跌(die)落(la))和(hu)電(dian)壓(ya)上(shang)升(sheng)(電(dian)壓(ya)隆(long)起(qi))的(di)總(zong)稱(chen)。
(2) 頻(pin)率(shuai)偏(pian)差(chai)(friquency deviation)：對(dui)頻(pin)率(shuai)質(zhi)量(liang)的(di)要(yao)求(qiu)全(quan)網(wang)相(xiang)同(tong)，不(bu)因(yin)用(yong)戶(hu)而(er)異(yi)，各(ge)國(guo)對(dui)於(yu)該(gai)項(xiang)偏(pian)差(chai)標(biao)準(zhun)都(du)有(you)相(xiang)關(guan)規(gui)定(ding)。
(3) 電(dian)壓(ya)三(san)相(xiang)不(bu)平(ping)衡(heng)(unbalance)：表(biao)現(xian)為(wei)電(dian)壓(ya)的(di)***大(dai)偏(pian)移(yi)與(yu)三(san)相(xiang)電(dian)壓(ya)的(di)平(ping)均(jun)值(zhi)超(chao)過(guo)規(gui)定(ding)的(di)標(biao)準(zhun)。
(4) 諧(xie)波(bo)和(hu)間(jian)諧(xie)波(bo)(harmonics & inter-hamonics)：含(han)有(you)基(ji)波(bo)整(zheng)數(shuo)倍(bei)頻(pin)率(shuai)的(di)正(zheng)弦(xian)電(dian)壓(ya)或(huo)電(dian)流(liu)稱(chen)為(wei)諧(xie)波(bo)。含(han)有(you)基(ji)波(bo)非(fei)整(zheng)數(shuo)倍(bei)頻(pin)率(shuai)的(di)正(zheng)弦(xian)電(dian)壓(ya)或(huo)電(dian)流(liu)稱(chen)為(wei)間(jian)諧(xie)波(bo)，小(xiao)於(yu)基(ji)波(bo)頻(pin)率(shuai)的(di)分(fen)數(shuo)次(ci)諧(xie)波(bo)也(ye)屬(zhu)於(yu)間(jian)諧(xie)波(bo)。
(5) 電(dian)壓(ya)波(bo)動(dong)和(hu)閃(shan)變(bian)(fluctuation & flicker)：電(dian)壓(ya)波(bo)動(dong)是(shi)指(zhi)在(zai)包(bao)絡(lao)線(xian)內(nei)的(di)電(dian)壓(ya)的(di)有(you)規(gui)則(ze)變(bian)動(dong)，或(huo)是(shi)幅(fu)值(zhi)通(tong)常(chang)不(bu)超(chao)出(chu)0.9～1.1倍(bei)電(dian)壓(ya)範(fan)圍(wei)的(di)一(yi)係(ji)列(lie)電(dian)壓(ya)隨(sui)機(ji)變(bian)化(hua)。閃(shan)變(bian)則(ze)是(shi)指(zhi)電(dian)壓(ya)波(bo)動(dong)對(dui)照(zhao)明(ming)燈(deng)的(di)視(shi)覺(jue)影(ying)響(xiang)。
