Isihlungi Esisebenzayo Esivumelanayo (AHF)—Isigaba Esisodwa
Isifinyezo somkhiqizo:
Izihlungi ezisebenzayo ze-harmonic (AHF) ziyimpendulo yokugcina ezinkingeni zekhwalithi yamandla ezibangelwa ukuhlanekezelwa kwe-waveform, isici samandla aphansi, ukuhluka kwamandla kagesi, ukushintshashintsha kwamandla kagesi kanye nokungalingani komthwalo ezinhlobonhlobo zamasegimenti nezinhlelo zokusebenza.Ziwuhlobo olusebenza kahle kakhulu, oluhlangene, oluguquguqukayo, olumodulayo nolungabizi kakhulu lwezihlungi zamandla asebenzayo (APF) ezinikeza impendulo esheshayo nephumelelayo ezinkingeni zekhwalithi yamandla ezinhlelweni zamandla kagesi anamandla aphansi noma aphezulu.Anika amandla isikhathi eside sokuphila kwemishini, ukwethembeka okuphezulu kwenqubo, umthamo othuthukisiwe wesistimu yamandla nokuzinza, nokuncipha kokulahlekelwa kwamandla, okuhambisana nezindinganiso zekhwalithi zamandla ezifunwa kakhulu namakhodi egridi.
Ama-AHF asusa ukuhlanekezela kwe-waveform emithwalweni efana ne-harmonics, i-harmonics kanye ne-notching, kanye nama-voltage e-harmonic abangelwa ama-harmonic currents, ngokujova ngesikhathi sangempela amandla amanje ahlanekezelwe wobukhulu obufanayo kodwa okuphambene nesigaba sohlelo lwamandla kagesi.Ngaphezu kwalokho, ama-AHF angakwazi ukunakekela ezinye izinkinga ezimbalwa zekhwalithi yamandla ngokuhlanganisa imisebenzi ehlukene kudivayisi eyodwa.
Isimiso sokusebenza:
I-CT yangaphandle ithola umthwalo wamanje, i-DSP njenge-CPU inezibalo zokulawula ingqondo ezithuthukile, ingalandelela ngokushesha ukwaziswa kwamanje, ihlukanise umthwalo wamanje emandleni asebenzayo namandla asebenzayo ngokusebenzisa i-FFT ehlakaniphile, futhi ibala okuqukethwe kwe-harmonic ngokushesha nangokunembile.Bese ithumela isignali ye-PWM ebhodini langaphakathi labashayeli be-IGBT ukuze ilawule i-IGBT ivule futhi iyivale kumafrikhwensi angu-20KHZ.Ekugcineni ikhiqiza isinxephezelo sesigaba esiphambene ekufakweni kwe-inverter, ngesikhathi esifanayo i-CT iphinde ithole impendulo yamanje kanye nembi ephumayo iya ku-DSP.Bese i-DSP iqhubeka nokulawula okunengqondo okulandelayo ukuze kuzuzwe uhlelo olunembe kakhudlwana futhi oluzinzile.
