Nrog rau cov kev xav tau ntawm kev tsim kho kev lag luam, txhawm rau txo cov load ntawm lub kaw lus thiab txuag hluav taws xob, muaj coob tushloov pauv zaus inverter yog siv nyob rau hauv industrial zaus.Kev siv ntawmzaus converter tuaj yeem ua tiav cov txiaj ntsig txuag hluav taws xob, tab sis nws kuj coj tau lwm yam teeb meem xws li kev sib haum xeeb.Peb tau ntsib ib qho chaw zoo heev uas muaj ntau lub zog hluav taws xob inverters tau siv los tswj cov twj tso kua dej.Kev ua haujlwm ntawm ntau cov khoom siv inverter ua rau muaj kev sib haum xeeb loj hauv lub cev, uas cuam tshuam rau kev nyab xeeb thiab ruaj khov ntawm lub kaw lus.
Los ntawm qhov kev xeem waveform, lub ntsiab harmonic distortion txiav txim yog 5, 7 harmonics.Ua ntej kev ua haujlwm ntawmAPF, tag nrho harmonic distortion tus nqi ntawm lub system tau mus txog 39.5%.Tom qab kev ua haujlwm ntawmactive harmonic lim, tag nrho cov harmonic distortion tus nqi ntawm lub system yog txo mus rau li 6%, lub waveform yog rov qab mus rau qhov qub, thiab cov harmonics ntawm txhua qhov kev txiav txim raug txo kom tsawg.Los ntawm daim duab 1 mus rau daim duab 4, peb tuaj yeem pom meej meej tias cov nyhuv ntawm kev sib haum xeeb tswj tom qab sivnquag limyog pom tseeb heev thiab siv tau.
Kev puas tsuaj ntawm harmonics yog qhov hnyav heev.Harmonics txo qhov kev ua tau zoo ntawm kev tsim khoom, kev sib kis thiab kev siv hluav taws xob, overheat cov khoom siv hluav taws xob, tsim kev co thiab suab nrov, thiab ua rau lub rwb thaiv tsev laus, ua rau lub neej luv luv, thiab txawm tias ua haujlwm tsis zoo lossis hlawv.Harmonics tuaj yeem ua rau lub cev sib luag hauv zos lossis cov resonance hauv lub zog, uas ua rau cov ntsiab lus sib haum xeeb thiab ua rau lub capacitor thiab lwm yam khoom siv hlawv.Harmonics kuj tuaj yeem ua rau kev ua haujlwm tsis zoo ntawm kev tiv thaiv relay thiab cov khoom siv tsis siv neeg, ua rau tsis meej pem hauv kev ntsuas hluav taws xob.Sab nraum lub zog hluav taws xob, kev sib haum xeeb tuaj yeem ua rau muaj kev cuam tshuam loj rau cov khoom siv sib txuas lus thiab cov khoom siv hluav taws xob.
Covactive zog limyog txuas nrog lub hwj chim system nyob rau hauv parallel, los ntawm sab nraud tam sim no transformer coj mus kuaj peb theem tam sim no.Lub chaw tswj hwm tseem ceeb suav cov nqi them tam sim no thiab xa cov lus txib mus rau IGBT, IGBT dynamically kho qhov zaus hloov mus rau qhov ua tau zoo thiabAHFkom offset harmonic tam sim no.
