PA的IEC諧波ZLG致遠(yuǎn)電子提供的PA系列功率分析儀全系支持IEC諧波測(cè)試功能，PA功率分析儀將原始采樣點(diǎn)進(jìn)行DFT處理，將信號(hào)分解成不同頻率的諧波進(jìn)行分析，根據(jù)IEC61000-4-7的規(guī)范計(jì)算出相應(yīng)結(jié)果并顯示數(shù)據(jù)，包括諧波/間諧波子組、功率譜、諧波/間諧波指標(biāo)。同時(shí)PA系列功率分析儀可以選擇顯示標(biāo)準(zhǔn)，實(shí)現(xiàn)IEC61000-3-2標(biāo)準(zhǔn)的顯示與對(duì)比，如下圖所示，用戶可以自己選擇A/B/C/D類別設(shè)備，選擇50Hz/60Hz頻率，選擇對(duì)應(yīng)標(biāo)準(zhǔn)和類別之后，PA功率分析儀會(huì)自動(dòng)顯示出諧波列表和對(duì)應(yīng)類別的限制。

但是VVVF缺點(diǎn)是輸入功率因數(shù)比較低，諧波電流大，直流電路需要大的儲(chǔ)能電容。變頻器的主回路構(gòu)成：電源輸入—整流橋—啟動(dòng)電阻—母線電容—制動(dòng)單元（制動(dòng)電阻）—逆變橋—電源輸出。主電路是給異步電動(dòng)機(jī)提供調(diào)壓調(diào)頻電源的電力變換部分，它由三部分構(gòu)成：整流電路：將工頻電源轉(zhuǎn)變?yōu)橹绷?；平波回路：吸收在變流器和逆變器產(chǎn)生的電壓脈動(dòng)；逆變電路：將直流轉(zhuǎn)變?yōu)轭l率可調(diào)的交流電。主要參數(shù)測(cè)量對(duì)與其工作系統(tǒng)主要是由變頻器和變頻電機(jī)兩部分組成。
