Isihluzo esisebenzayo seHarmonic (AHF)—Isigaba esinye
IsiShwankathelo seMveliso:
Izihluzi ezisebenzayo ze-harmonic (AHF) ziyimpendulo yokugqibela kwiingxaki zomgangatho wamandla obangelwa kukugqwethwa kwe-waveform, into encinci yamandla, ukwahluka kombane, ukuguquguquka kwamandla ombane kunye nokungalungelelani komthwalo kuluhlu olubanzi lwamacandelo kunye nezicelo.Ziyintsebenzo ephezulu, i-compact, i-flexible, i-modular kunye ne-cost-effective filters yamandla asebenzayo (APF) abonelela ngempendulo ekhawulezileyo nesebenzayo kwiingxaki zomgangatho wamandla kwiinkqubo zamandla ombane ombane ophantsi okanye ophezulu.Bavumela ubomi bezixhobo ezinde, ukuthembeka kwenkqubo ephezulu, ukuphuculwa komthamo wenkqubo yamandla kunye nokuzinza, kunye nokunciphisa ilahleko yamandla, ukuthobela eyona migangatho ifunwayo yomgangatho wamandla kunye neekhowudi zegridi.
Ii-AHFs zisusa ukugqwetheka kwe-waveform kwimithwalo efana ne-harmonics, i-harmonics kunye ne-notching, kunye ne-harmonic voltages ezibangelwa yimisinga ye-harmonic, ngokutofa ngexesha lokwenyani umsinga ogqwethekileyo wobukhulu obufanayo kodwa ngokuchaseneyo kwinqanaba lenkqubo yamandla ombane.Ukongeza, ii-AHFs zinokukhathalela ezinye iingxaki zomgangatho wamandla ngokudibanisa imisebenzi eyahlukeneyo kwisixhobo esinye.
UmGaqo wokuSebenza:
I-CT yangaphandle ibona umthwalo wangoku, i-DSP njenge-CPU ine-arithmetic yokulawula i-logic ephuculweyo, inokulandelela ngokukhawuleza umyalelo wangoku, ukwahlula umthwalo wangoku kumandla asebenzayo kunye namandla asebenzayo ngokusebenzisa i-FFT ehlakaniphile, kwaye ibala umxholo we-harmonic ngokukhawuleza nangokuchanekileyo.Emva koko ithumela umqondiso we-PWM kwibhodi yangaphakathi yomqhubi we-IGBT ukulawula i-IGBT ngokuvula kunye nokuvala kwi-20KHZ frequency.Ekugqibeleni ivelisa imbuyekezo yesigaba esichaseneyo ngoku kwi-inverter induction, kwangaxeshanye i-CT iphinda ibone imveliso yangoku kunye nengxelo engalunganga iya kwi-DSP.Emva koko i-DSP iqhubela phambili nolawulo olulandelayo olunengqiqo ukuphumeza inkqubo echaneke ngakumbi kwaye izinzile.
