Active harmonic limtau dhau los ua ib feem tseem ceeb ntawm cov khoom siv hluav taws xob zoo tsim tawm hauv cov chaw lag luam thiab kev lag luam.Lub zog muaj zoglimNws yog ib qho tseem ceeb los txo cov harmonics thiab tswj kev ua haujlwm ntawm cov tshuab hluav taws xob.Tshwj xeeb, peb-theem active harmonic lim tuaj yeem pab daws teeb meem hluav taws xob zoo hauv tsev kho mob.Cov tsev kho mob xav tau cov tshuab hluav taws xob zoo los txhawb cov cuab yeej kho mob thiab tswj kev ua haujlwm tseem ceeb hauv lub neej.Cov tshuab hluav taws xob hauv tsev kho mob tuaj yeem ntsib ntau yam kev cuam tshuam, suav nrog dips, swells, voltage transients, thiab electromagnetic cuam tshuam.Harmonics tsim los ntawm cov khoom siv hluav taws xob tuaj yeem cuam tshuam lub tsev kho mob lub zog tsis zoo thiab ua rau cov khoom puas tsuaj, ua rau lub cev tsis ua haujlwm thiab txo cov neeg mob.Active harmonic filters yog cov khoom tseem ceeb uas pab tswj lub zog zoo hauv tsev kho mob.Cov thev naus laus zis no tsis tu ncua saib xyuas kev sib haum xeeb sib txawv thiab lim tawm cov cim tsis xav tau ua ntej lawv tuaj yeem ua rau lub cev puas tsuaj.Active harmonic filters kho waveform distortion thiab muab lub zog zoo rau cov tsev kho mob cov chaw los ntawm kev sib txuas cov thev naus laus zis xws li capacitors, inductors, thiab cov khoom nquag.Active harmonic filters yog tsim los ua hauj lwm nyob rau hauv ib tug parallel configuration nrog lub mains Circuit Court thaum qhia ntxiv tam sim no rau lub system.Qhov tam sim no yuav pab tsim kom muaj kev sib haum xeeb uas sib npaug hauv amplitude tab sis rov qab nyob rau hauv theem rau cov uas tam sim no nyob rau hauv hluav taws xob system, li no ho txo cov harmonics.Lub active filtered tam sim no waveform yog superimposed ntawm unfiltered tam sim no waveform los ua ib tug waveform nrog qis tag nrho harmonic distortion.Ib qho kev tshawb fawb tsis ntev los no qhia tau hais tias cov lim dej sib haum xeeb tau ua tiav hauv tsev kho mob li cas.Ib lub tsev kho mob 300-txaj hauv Suav teb tau ntsib teeb meem tsis zoo ntawm lub zog vim muaj kev sib haum xeeb cuam tshuam los ntawm cov khoom siv hluav taws xob uas dav siv nyob rau hauv qhov chaw.Cov distortions no zoo heev tshaj qhov tau txais, ua rau cables thiab transformers overheat, shortening lub neej ntawm cov cuab yeej thiab ua rau nquag tu thiab hloov.Lub tsev kho mob tau teeb tsa 100APeb-theem active harmonic limlos daws cov teeb meem no.Cov cuab yeej txo qis tag nrho kev sib haum xeeb tsis sib haum (THD) los ntawm 16% mus rau tsawg dua 5%.Lub lim dej tseem ua kom lub zog muaj zog los ntawm ib puag ncig 0.86 kom ze rau 1, txo qis kev siv hluav taws xob hauv lub cev.Cov lim dej ua kom muaj kev sib haum xeeb ua rau muaj kev ua tau zoo ntawm cov tshuab hluav taws xob thiab ua kom lub cev muaj kev ntseeg siab los ntawm kev tiv thaiv cov khoom siv tsis ua haujlwm, txuag tsev kho mob lub sijhawm thiab nyiaj txiag tseem ceeb.Hauv cov ntsiab lus,active harmonic limmuab cov txiaj ntsig tseem ceeb hauv kev tswj xyuas hluav taws xob zoo hauv tsev kho mob.Cov khoom siv hluav taws xob ntau thiab ntau dua yog siv hauv tsev kho mob, thiab kev sib haum xeeb uas lawv tsim tuaj yeem ua rau muaj teeb meem loj heev.Active harmonic filters yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob zoo uas lim tawm qhov tsis xav tau kev cuam tshuam thiab muab lub zog zoo rau cov tsev kho mob.Cov lim dej ua kom muaj kev sib haum xeeb tuaj yeem txo qis kev siv hluav taws xob, txo kev siv zog ua haujlwm, thiab thaum kawg pab cov tsev kho mob muab kev saib xyuas cov neeg mob zoo.
